Initially, the MA 51 model trains, which had previously been used on Line 13 until it joined Line 14, circulated on the tracks of Line 10. These trains were first constructed with three cars on four

Route and stations

Line 10 measures across 23 stations and one ghost station, ''Croix-Rouge'', closed in 1939. The route is entirely underground. File:Paris Metro Ligne 10.svg, Geographically accurate path of Paris Métro Line 10


List of stations

Beginning at the western terminus of Line 10, the first train that leaves the station ''Porte d'Auteuil'' heads towards the terminus of ''gare d'Austerlitz''. At this time, passengers may ride on the turn-around track, which is closed to passengers for the rest of the day. SIEL, ''système d'information en ligne'', gives passengers on the platforms the time-to-arrival of the next two trains, and has been operational since 1 July 2008. At the terminus ''Boulogne – Pont de Saint-Cloud (Rhin et Danube)'', because of the proximity to the

, there are no tracks behind the station to allow the train to reverse directions. Instead, trains are received alternately on each side of the platform and leave directly in the opposite direction. Due to the narrowness of the ''rue du Château'', under which line 10 passes, the stations ''Boulogne – Pont de Saint-Cloud (Rhin et Danube)'' and ''Boulogne – Jean Jaurès'' have only one central platform used for both directions. After this last station, tracks run for to reconnect trains to ''Auteuil''. Tracks 1 (towards ''Austerlitz'') must successively pass under the

, followed by the platforms for the connections to ''Auteuil'' and ''Murat'' before ascending to service the station ''Michel – Ange – Molitor''. In order to achieve this, ramps reaching a descent of up to a 40‰ grade are used. Tracks 2 (towards Boulogne) are separated by the loop on the level of the avenue du Général-Sarrail with a bend and a slope of 40‰. The loop to ''Auteuil'' is situated in the neighborhood of Auteuil: tracks 1 and 3 of the loop border the central platform of ''Miche-Ange – Molitor''. Afterwards, they pass under the rails of line 9, until combining at the arrival to ''Chardon-Lagache'' with a unique platform. Finally, tracks 1 reach the station ''Mirabeau'' and then go towards ''Austerlitz''. Tracks 2, coming from ''Austerlitz'', follow a very peculiar profile and do not service the station ''Mirabeau'', instead crossing behind it with a sharp ramp due to the great depth of the line after traversing the Seine. Furthermore, in order to reach the station ''Église d'Auteuil'', the tracks must climb even higher very close to the station's foundation. Following this, tracks 2 of the line pass behind tracks of line 9 and arrive at the station ''Michel-Ange – Auteuil'', which has a central platform surrounded by tracks 2 and tracks H coming from a connection with line 9. Arriving at ''Porte d'Auteuil'', the tracks separate to form the complexity of tracks that head towards Boulougne, a maintenance station, ''Murat'', or towards ''Michel-Ange – Molitor''. After the station ''Mirabeau'', the line crosses the Seine via an underwater tunnel and reaches the station ''Javel – André Citroën'' by way of a 40‰ ramp after passing under tracks of line C of the RER. Following this, the line follows ''avenue Émile-Zola'' to arrive at the stations ''Charles Michels'' and ''Avenue Émile Zola'' before joining the ''rue du Commerce''. When the line reaches the station ''La Motte-Picquet – Grenelle'', the two tracks separate: tracks 1 are situated in a half-station with platform 1 of line 8 and tracks 2 service a half station but without tracks 2 of line 8 which are situated below. Before arriving at the station ''Ségur'', the line passes under the Rapp intake. It then services the stations ''Duroc'', ''Vaneau'' and ''Sèvres – Babylone''. The line continues eastward and passes through the vacant station ''Croix-Rouge'', which was closed on 2 September 1939. Finally, the line arrives at ''Mabillon''. Beginning at ''Odéon'' the route of line 10 becomes complixed as it must pass an intersection with line 4. The two tracks part in order to yield passage to the connection tracks that arrive in the middle of the circulation tracks and level off at the station ''Cluny – La Sorbonne''. The connection tracks rejoin the other tracks of line 10 before the station ''Maubert – Mutualité''. The same principle is in effect with the connection to line 7 but these double tracks pass under the tracks of line 10 before the station ''Cardinal Lemoine''. When the route reaches the station ''Jussieu'', lines 7 and 10 follow parallel routes which allows for the platforms of the two lines to be side by side. Finally, the line follows bends in both direction under the ''Jardin des plantes'' to arrive at the terminus, ''Gare d'Austerlitz''. The arrival is situated under the arrivals hall of the train station, and the turn-around loop is under the railroad tracks. This cul-de-sac is peculiar in the sense that it is configured to receive an underwater passing coming from the ''gare de Paris-Lyon''.

Renamed stations

Five stations on line 10 have changed names of the course of the years: *''La Motte-Picquet'' became ''La Motte-Picquet – Grenelle'' in November 1913; *''Wilhem'' became ''Église d'Auteuil'' on 15 May 1921; *''Beaugrenelle'' became ''Charles Michels'' on 14 July 1945; *''Gare d'Orléans – Austerlitz'' became ''Gare d'Austerlitz'' in 1979; *''Cluny'' became ''Cluny – La Sorbonne'' on 17 February 1988.


Themed and otherwise unique stations

Some stations on the line are decorated with a particular cultural theme in mind: The station ''Javel – André Citroën'' presents the life and enterprise of
André Citroën André-Gustave Citroën (; 5 February 1878 – 3 July 1935) was a French industrialist and the founder of French automaker Citroën. He is also remembered for his application of double helical gears. Life and career Born in Paris in 1878, A ...

These decorations, however, were removed during the 2000s in light the renovation project "Renouveau du Métro". The halls used for connections in the station ''La Motte-Picquet – Grenelle'' are decorated with various coats of arms of the Toussaint-Guillaume Picquet de la Motte family (blue with three golden chevrons, accompanied by three silver arrowheads). A fresco represents the ''barrière de la Cunette'', one of the doors of the

Junctions

The line contains six junctions with other lines of the network: *with line 9 via ''Voie Murat'' and the depots located to the southwest of the station ''Porte d'Auteuil'' on the tracks of the old entrance that are no longer used in commercial service; *with line 9 at the entrance to the station ''Michel-Ange – Auteuil'', on the tracks in the direction of ''Boulogne''; this intersection runs alongside the platform of the station ''Michel-Ange – Auteuil'', the edge of the platform being protected by fencing, and then intersects at the terminus. *with line 8 at the entrance to the station ''La Motte-Picquet – Grenelle'', on the tracks heading towards ''Boulogne''; *a tunnel without an intersection exists towards line 13, between the stations of ''Duroc'' and ''Vaneau''; it dates back to the old route of line 10 towards ''Invalides''; *with line 4 via a dead end in the east of the station ''Odéon'', but intersecting in actuality at the east of the station ''Cluny – La Sorbonne'' after having traveled to the center of the station without bordering a platform; the intersection occurs between the two tracks of line 10 at the station ''Cluny – La Sorbonne'' where three tracks form but are then combined into the two of line 10; *with line 7 at the exit of the station ''Maubert – Mutualité'' in the direction of ''Gare d'Austerlitz''; this two-track connection, used commercially between 1930 and 1931, is separated from line 10 by a strong slope between the two rails.


Depots

Trains on line 10 are serviced by the depots at Auteuil, which are connected to the tracks of the terminus ''Porte d'Auteuil''. These depots are entirely underground; other than tunnels, an escalator located on the sidewalk of the ''avenue du Géneral-Sarrail'' provides access. The depots are connected to line 9 as well; however, line 9 has not used these depots since the opening of those at ''Boulogne'' connected to ''Pont de Sèvres''. Both heavy and regular (batteries, tune-ups, and repainting) maintenance of the trains of line 10, as with all other trains on the rail network, takes place at the depot at ''Choisy''. Opened in 1931, it is situated in the 8th arrondissement of Paris, close to the

Usage


Service

In 2008, one complete trip across the line took twenty-eight minutes in the west–east direction and twenty-nine minutes in the opposite direction. As with all lines of the Paris métro (with the exception of the ''bis'' lines), the first departure of the day leaves the station at 5:30 am. A train leaves from ''Boulogne – Pont de Saint-Cloud'' at 5:35 am, preceded by the first departure on the line from ''Porte d'Auteuil'' at 5:30 am, which is also the only train that will take passengers on the turn-around loop at ''Auteuil''. The last train leaves ''Boulogne – Pont de Saint Cloud'' at 12:47 am destined for ''Gare d'Austerlitz''. From ''Gare d'Austerlitz'', the last train leaves at 12:35 am for ''Boulogne – Pont de Saint-Cloud'' and another for ''Porte d'Auteuil'' at 12:51 am. From Friday night to Sunday and during holidays, the last departure from ''Boulogne – Pont de Saint-Cloud'' leaves at 1:47 am for ''Gare d'Austerlitz''. From this terminus, the last departure takes place at 1:35 am for ''Boulogne – Pont de Saint-Cloud'' and at 1:46 am for ''Porte d'Auteuil''. Trains on line 10 are less frequent than those on other lines: the average time between trains is between three and five minutes during the day and between eight and nine minutes late night. On Sunday mornings, the time between trains is between six and seven minutes, and about ten minutes Friday night, and all of Saturday, Sunday, and holidays after 12:30 am (after 1:15 am on Friday and Saturday nights).


Train sets

Line 10 has always been unique with respect to its train sets. Before World War II, it was unusual in that it was circulated by Sprague model trains with two cars circulating alone as passenger traffic was very light. Until 1976, old Spragues circulated the line with four cars each (two motor cars with four motors). Line 13 transformed in the middle of the 1970s as a result of its junction with the old line 14, and a more modern and better performing train set, MF 67, was put in service. Beginning 28 April 1975, the old MA 51 train sets of line 13, numbering 52 in total, were progressively transferred to line 10 and drastically modernized. The cars were repainted, their outer bodies and seats replaced, and modern fluorescent lighting installed. They circulated in permanent sets of six. By June 1976, all of the trains had been transferred to line 10 and put into service, where they eventually ended their career. In order to reform the old Sprague models and because of an insufficient number of trainsets, some MF 67 train sets of the A/D model were placed on line 10 as well. The MA 1951 model was introduced between 1988 and 1994, and afterwards were replaced by MF 67 series E models coming from line 7bis, which itself got the

trains that also had an unusual wheel arrangement (in that case, single axle bogies). The MF 67 will be replaced by MF 19 train sets in 2025..


Operational personnel

Employees of the métro can be divided into two categories: station agents and conductors. Station agents are responsible for ticket sales, verifying passenger tickets, general management of the station, as well as other tasks as the needs of the service dictate. The conductors assure the functioning of the trains. Service is divided into three shifts: day, mixed, and night.


Fares and financing

Fares on line 10 are identical to those on the rest of the transport network and are accessible via the same tickets. A ''ticket t+'' allows for a single one-way trip with one or more connections with other lines of the metro as well as inner-city RER lines. The financing of the functioning of the line, maintenance, cars, and employees is handled by the RATP; however, fares are dictated legislatively and income from ticket sales do not completely cover the network's entire costs. This difference is made up by funding from the ''Syndicat des transports d'Île-de-France (STIF)'' (''Île-de-France Transportation Union''), which has been presided over since 2005 by the president of the ''Conseil régional d'Île-de-France'', composed of locally elected persons. This group defines the general conditions of use as well as the duration and frequency of services. Financing is assured by a 3.5 billion euro subsidy made possible through transportation deposits paid by corporations and contributions from public community groups.


Traffic

Line 10 is a secondary line on the Parisian network, and the number of total passengers amounts to only a little more than a quarter of the total passengers of line 1. Line 10 is the least-traveled line on the network, with the exception of the short 3bis and 7bis lines. Between 1992 and 2004, traffic has grown a total of 4.7%, which puts the line in 8th place in terms of growth (behind line 14). The most frequented station of the line, in annual traffic with all lines considered, is ''Gare d'Austerlitz'' with 8.73 million passengers. In 1998, daily traffic on line 10 averaged 148,613 passengers for each day the line was open, with 104,041 on Saturdays and 53,051 on Sundays.


Tourism

By way of its route, line 10 is limited to the south of the capital and, passing by few centers of activities, is rarely travelled by Parisians. With the exception of the oriental section ''Gare d'Austerlitz – Duroc'', traffic is very light. On the other hand, the line is especially trafficked by students, as it links multiple important university centers such as the ''campus de Jussieu'',
la Sorbonne The University of Paris (), known Metonymy, metonymically as the Sorbonne (), was the leading university in Paris, France, from 1150 to 1970, except for 1793–1806 during the French Revolution. Emerging around 1150 as a corporation associated wit ...

Service to Auteuil

Métro line 10 resulted from the connection of two sections, east and west, which created a set of distinct lines. The west section, from ''La Motte-Picquet'' to ''Grenelle à Porte d'Auteuil'' was initially part of line 8. Line 8 was the last line adopted for the agreement of 30 March 1898, and consisted of a route between Opéra and Porte d'Auteuil via Grenelle. In March 1910, it was decided that the line would have a branch, a concept that had just been inaugurated with line 7. Trains would branch at ''Grenelle'' station and run to the Porte de Sèvres (now ''Balard''). The trains would run along the two branches alternately. Work on the line began in April 1908 with an underwater construction site in the Seine between the stations of ''

A final caisson was buried in an excavation made under the tracks, but the lack of height required scaffolding to be used and the casing was gradually extended as the caisson was installed. Work began in August 1907 but was not finished until 1913, also delayed by the 1910 Great Flood of Paris. on two levels, which allowed for the simultaneous departure of trains towards Auteuil from a single platform and the planned branch towards the ''Porte of Sèvres'' on one level, as well as the arrival of trains in the opposite direction from both branches at an island platform on another level. While work at Pont Mirabeau was ongoing, the line was opened to the public on 13 July 1913 between ''Beaugrenelle'' and ''Opéra'' stations and was extended on 30 September 1913 to ''Porte d'Auteuil''.Tricoire 1999b, p. 250. In 1914, line 8 contained fifteen stations between ''Porte d'Auteuil'' and ''Opéra''.


The start of line 10

The principle of a circular line, conceived at the start of the 1900s, led to the creation of a line called ''Ceinture intérieure des Invalids aux Invalides'' ("inner belt from Invalides to Invalides"). This concept was designated as line 10 in 1907.Tricoire 1999b, p. 280. On the right bank, the line had to use the platforms of line 8, and as such a set of complex connections were created under the esplanade of Invalides with the creation of a large loop. However, in October 1912, the principle of an inner belt was abandoned and line 10 was left to connect Invalides to

began in 1913 and ended on 18 March 1920. However, the prospect of low revenues that would certainly result from such a small section serving only neighborhoods of little activity caused the Compagnie du chemin de fer métropolitain de Paris (CMP) to delay the construction and postpone the opening and what would surely be a resulting deficit as far back as possible. Finally, after being required by the city to do so, the company opened the line for use on 30 December 1923. The new line 10 consisted of six stations, each of which with a vaulted ceiling. The line ran under the ''Rue de Four'', the ''Rue de Sèvres'', and the ''Boulevard des Invalides'' with a very pronounced bend at Duroc. The line quickly became a financial disaster for the CMP, with an average of at most 1,000 passengers per day and per station. The terminus of ''Croix-Rouge'' received only four hundred daily passengers, and ''Varenne'' station , the least frequented station of the entire métro network, saw only three hundred passengers per day. As a result, only ten trains of six cars serviced the line, two motor cars serving as first class cars, which saw so little traffic that they were replaced with simple motors equipped only with two conductor cars.


Extensions to the east

Extension on the line followed in 1923 between ''Croix-Rouge'' and ''Odéon'', creating a section long connecting two additional stations. This tiny extension brought an increase of traffic due to its connection with line 4. It began serving ''Mabillon'' on 10 March 1925 and ''Odéon'' on 14 February 1926.Robert 1983, p. 112. The City of Paris decided in 1925 to connect three lines to line 10. To this end, many possibilities were examined. It was first envisioned to extend the line to ''Bastille'' via ''Place Jussieu'', to complement the creation of a circular line. However, the abandonment of the circular line project made this extension of little use and it would have required an underwater section very close to one already planned for line 7 toward ''Pont de Sully''. Eventually, the city chose to end the line at '' Jussieu'' on the left bank, which would create a connection with line 7. Because of the difficulties the construction of an underwater section would present, and the time it would require, it was planned in 1927 to link line 10 to an extension of line 7 between ''Jussieu'' and ''Porte de Choisy'' that was already underway. With this in mind, it was decided to create a connection with two platforms between the stations of ''Maubert'' of line 10 and ''Place Monge'' of the future line 7 so that line 10 would temporarily use this section of line 7 while the underwater tunnel that connected the northern and southern sections of the line was constructed. The tunnel between the

and Porte de Choisy was delivered by the city to the CMP in November 1929. In less than three months, the platform was completed, the lighting was installed, and access was made possible. Line 10 arrived at ''

'' on 7 March of the same year, using the platforms of the future line 7. Before its reconstruction, the line served nineteen stations. The route of this new section runs parallel to those of above-ground transport services that were especially crowded. As a result, line 10 saw a rapid increase in use; however, its route on the left bank did not serve the needs of passengers well and therefore many used line 10 as a way to make connections to other lines, particularly line 5 at ''Place d'Italie'' and line 12 at ''Sèvres-Babylone'' to continue on to destinations on the right bank. The western section between Sèvres and Invalides remained lightly used.


Modification of lines during the 1930s

At the same time that the underwater crossing of line 7 was completed, line 10's tunnel from ''Maubert'' to ''Jussieu'' was also completed. The line crossed the line towards Place Monge by a

. On 21 April 1931, the underwater tunnel of line 7 was completed as far as Jussieu.Tricoire 1999b, p. 281. The completion of this station necessitated a considerable amount of work with regards to its location under the Halle-aux-Vins, upon which the Faculté des sciences de Jussieu is located. Here, the track structure is built on concrete beams supported on both sides. The platforms of lines 7 and 10 are next to each other. On 21 April 1931, the operation of the two lines was modified. Line 7 was extended from ''Sully-Morland'' on the right bank to ''Porte d'Ivry'' and the trains of line 10 stopped using the middle section of line 7 and instead began the use of the new tracks to ''Jussieu''. At the same time, '' Cardinal Lemoine station'' was opened. Traffic on line 10 diminished significantly but also became more evenly distributed across its sections. The line saw its largest modification on its western section in 1937, which impacted several lines. At the time, the route of line 10 did not attract a large number of passengers; however, the development of a section between ''La Motte-Picquet'' and ''Balard'' had already been agreed upon, so the creation of line 14, ''Porte de Vanves – Bienvenüe'' (today a part of line 13), stayed in the plans. These considerations led the ''Conseil municipal de Paris'' (Municipal Council of Paris) to decide to have multiple extensions added and to carry out a partial restructuring of the lines. Line 8 was given a new terminus at ''Balard'' and the old section of line 8 between ''La Motte-Picquet'' and ''Porte d'Auteuil'' was incorporated into line 10. Meanwhile, the section of Line 10 between ''Duroc'' and ''Invalides'' was transferred to line 14. Work began at the end of 1934. A new section was constructed linking the station ''La Motte-Picquet'' in the west to ''Duroc'' in the east with a new intermediate station, ''Ségur''. The reconfiguration of the three lines' routes was planned so to minimize interruption while construction took place. The lines were shut down during a single night, between 26 and 27 July 1937. During this night, teams removed the rails on line 10 on the bend by ''Duroc'', while at the same time others modified the rails by ''La Motte-Picquet''. Still other teams changed the advisory signs of all involved stations, as well as the line maps in the stations and on the trains. On the morning of 27 July, line 10 was cut in two: from ''Jussieu'' to ''Duroc'' on one part, and from ''La Motte-Picquet'' to ''Porte d'Auteuil'' on the other. On 29 July, service began from ''Porte d'Auteuil'' to ''Jussieu''. Line 10 was now gradually approaching its current configuration. The objective was to link ''Porte d'Auteuil'' to ''Gare d'Austerlitz'' to form a more coherent east–west route. The extension from Jussieu to ''Gare d'Austerlitz'' is 1,027 metres long. Construction began in 1934; however, it ran into a number of difficulties resulting from its proximity to the Seine and the railway tracks of the ''Austerlitz-Gare d'Orsay'' line, which part of the line had to tunnel under. Construction of the infrastructure was completed on 14 September 1938, and the extension was opened to the public on 12 July 1939. In September 1939, World War II broke out and the stations of ''Croix-Rouge'' and ''Cluny-La Sorbonne'', considered too close to other stations, were closed. After these closures, the line encompassed 20 stations all together. On 3 June 1940, the bombing of

factories damaged the tunnel of line 10 between ''Chardon-Lagache'' and ''Mirabeau''. As a result, service was restricted to the section of ''Gare d'Austerlitz-Beaugrenelle'', which became ''Charles-Michels''. Three days later, a shuttle was put into service between ''Beaugrenelle'' and ''Porte d'Auteuil'', running on one track. Normal service was re-established on 8 June.


Westward expansion

There was a period of forty years between expansion projects. Finally, in 1977 a new expansion project began with the objective of improving the service to the municipality of

apart from Paris and its area is relatively large. The expansion work, with consisted of of track and two new stations, began in February 1977 and took place mostly in open cuts. The two stations contain island platforms due to the narrowness of the rail network, spanning only twelve metres. This constraint required a specific type of construction to assure the structural stability of the adjacent buildings during the settling of the ground. The stable layer of chalk under the ground allowed for the creation of grooves to support a temporary roof structure. Excavation began in a trench covered by the temporary roof slab. The double-track tunnel connects to the ''Auteuil'' loop via two single-track tunnels. For the first time on the Parisian network, the terminus did not contain a turn-back system behind the station due to lack of space, so the turn-back system is built in front of the station. The opening of this section, which is entirely underground, took place in two phases: the first expansion to ''Boulogne-Jean Jaurès'' was inaugurated on 3 October 1980, and the second section to ''Boulogne-Pont de Saint-Cloud'' was opened on 2 October 1981. Boulougne at first was served by only every other train, with the second train returning eastward via the loop at ''Auteuil''. After 6:40 pm, all trains served the entire line.Tricoire 1999b, p. 250., Following the opening of the '' Saint-Michel–Notre-Dame station'' on line B of the RER in February 1988, the station ''Cluny-La Sorbonne'', closed in 1939, was reopened to provide a connection with lines B and C of the RER.

Expansion projects

No expansion project has been officially scheduled for line 10 through the year 2030 in the schéma directeur de la région île-de-France (SDRIF). Nevertheless, many projects have been proposed over the years.


Westward

One proposal consists of expanding line 10 from ''Boulogne – Pont de Saint-Cloud'' to the train station ''gare de Saint-Cloud'', via an intermediate station at ''Parc de Saint-Cloud''. Such an expansion would total about in total. Line 10 would then have a connection with the tramway T2 at ''Parc de Saint-Cloud'' and with the Transilien network of ''Paris-St-Lazare'' at the train station ''gare de Saint-Cloud''. This westward expansion was not included in the SDRIF that was adopted in 2008, possibly due to the plan to create a southwestern branch of the Arc Express.


Eastward

A recurring request of passengers has been to extend line 10 eastward, traversing the Seine between ''gare d'Austerlitz'' and ''gare de Lyon'' to provide service to the latter as these two neighboring train stations are not linked to each other by any métro or RER line. The current configuration of the line and the substrate in the area of the proposed line would make such an extension difficult and therefore improbable. The extension most likely to be realized is along the RER C route (most likely under the ''rue du Chevaleret'' towards the 13th arrondissement, a neighborhood still poorly serviced despite the opening of line 14 to the station ''Olympiades'' and in consideration of the construction of a university in the Paris Rive Gauche neighborhood). In 2007, the ''Conseil de Paris'' deliberated on the importance of expanding line 10 to ''Ivry-sur-Seine''. The SDRIF adopted in 2008 does not include this proposal. However, it does state that ''optimization studies of service to Seine-Amont suggest that changes and/or expansions to lines 7, 10, and 14 may be necessary." In October 2008, one of the ''sociétés d'économie mixte de Paris'' (SEMAPA) requested a feasibility study to be conducted on an expansion from place Gambetta to Ivry-sur-Seine. An independent study was done by the ''syndicat des transports d'île-de-France'' (STIF), in which the stations ''Chevaleret'', ''Bibliothèque François Mitterrand'', ''Bruneseau'', ''Ivry – Nelson-Mandela'', and ''Ivry-Place Gambetta'' were included.
