Ballastless Track
A ballastless track or slab track is a type of railway track infrastructure in which the traditional elastic combination of ties/sleepers and ballast is replaced by a rigid construction of concrete or asphalt. Characteristics In ballastless tracks, the rails are rigidly fastened to special types of concrete ties/sleepers that are themselves set in concrete. Ballastless tracks therefore offer a high consistency in track geometry, the adjusting of which is not possible after the concreting of the superstructure. Therefore, ballastless tracks must be concreted within a tolerance of . The elasticity of the ballast in the traditional railway superstructure is replaced by flexibility between either the rails and the concrete ties/sleepers or the ties/sleepers and the concrete or asphalt slab as well inherent elasticity within the conglomerate of the tie/sleeper, whereas the concrete or asphalt slab is usually inelastic.

Track (rail Transport)
A railway track (British English and UIC terminology) or railroad track (American English), also known as permanent way or simply track, is the structure on a railway or railroad consisting of the rails, fasteners, railroad ties (sleepers, British English) and ballast (or slab track), plus the underlying subgrade. It enables trains to move by providing a dependable surface for their wheels to roll upon. Early tracks were constructed with wooden or cast iron rails, and wooden or stone sleepers; since the 1870s, rails have almost universally been made from steel. Historical development The first railway in Britain was the Wollaton Wagonway, built in 1603 between Wollaton and Strelley in Nottinghamshire. It used wooden rails and was the first of around 50 wooden-railed tramways built over the next 164 years. These early wooden tramways typically used rails of oak or beech, attached to wooden sleepers with iron or wooden nails. Gravel or small stones were packed around the s ...

Rolling Stock
The term rolling stock in the rail transport industry refers to railway vehicles, including both powered and unpowered vehicles: for example, locomotives, freight and passenger cars (or coaches), and non-revenue cars. Passenger vehicles can be un-powered, or self-propelled, single or multiple units. A connected series of railway vehicles is a train (this term applied to a locomotive is a common misnomer). In North America, Australia and other countries, the term consist ( ) is used to refer to the rolling stock in a train. In the United States, the term ''rolling stock'' has been expanded from the older broadly defined "trains" to include wheeled vehicles used by businesses on roadways. The word ''stock'' in the term is used in a sense of inventory. Rolling stock is considered to be a liquid asset, or close to it, since the value of the vehicle can be readily estimated and then shipped to the buyer without much cost or delay. The term contrasts with fixed stock (infrastru ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Rheda-Wiedenbrück Station
Rheda-Wiedenbrück station is a passenger station in the Westphalian town of Rheda-Wiedenbrück in the German state of North Rhine-Westphalia. It lies on the Hamm–Minden railway, one of the most heavily trafficked lines in Germany. The Warendorf Railway branches off to the west to Münster. The section of the Warendorf Railway running east to Lippstadt is now closed. The station is located north of central Rheda. History As part of the construction of its trunk line from Cologne via the Ruhr valley to Minden, the Cologne-Minden Railway Company (German, old spelling: ''Cöln-Mindener Eisenbahn-Gesellschaft'', CME) opened the Hamm–Minden line on 15 October 1847, including the Rheda-Wiedenbrück station, originally called ''Rheda in Westfalen''. After the nationalisation of the nominally private railway companies, the section from Warendorf via Rheda to Lippstadt of the Warendorf Railway was completed on 25 June 1887, originally crossing the railway station and the existing line ...

Rebar
Rebar (short for reinforcing bar), known when massed as reinforcing steel or reinforcement steel, is a steel bar used as a Tension (physics), tension device in reinforced concrete and reinforced masonry structures to strengthen and aid the concrete under tension. Concrete is strong under Compression (physics), compression, but has weak tensile strength. Rebar significantly increases the tensile strength of the structure. Rebar's surface features a continuous series of ribs, lugs or indentations to promote a better bond with the concrete and reduce the risk of slippage. The most common type of rebar is carbon steel, typically consisting of hot-rolled round bars with deformation patterns embossed into its surface. Steel and concrete have similar coefficient of thermal expansion, coefficients of thermal expansion, so a concrete structural member reinforced with steel will experience minimal differential stress (mechanics), stress as the temperature changes.

LGV Méditerranée
The LGV Méditerranée (French: ''Ligne à Grande Vitesse''; English: Mediterranean high-speed line) is a French high-speed rail line running between Saint-Marcel-lès-Valence, Drôme and Marseille, Bouches-du-Rhône, also featuring a connection to Nîmes, Gard (west of the line). It connects the regions of Provence-Alpes-Côte d'Azur and Occitanie to the LGV Rhône-Alpes, and from there to Lyon and the north of France. Construction costs rose to €3.8 billion; the line entered service in June 2001 following an inauguration by President Jacques Chirac. The commencement of service on this line has led to a reversal of the respective airplane and train markets: by making Marseille reachable in three hours from Paris—a distance of over —the train now handles two-thirds of all journeys on that route. LGVs Méditerranée, Rhône-Alpes and Sud-Est, when completed, also received their official nickname, the ''City To Coast (C2C) Highway'' ("Ville à la Mer").

Bözberg Rail Tunnel
The Bözberg Rail Tunnel is a railway tunnel in the Swiss canton of Aargau. It takes the Bözberg railway line of the Swiss Federal Railways under the Bözberg Pass between Effingen and Schinznach-Dorf. The original tunnel was opened during 1875; it is set to be closed to rail traffic during 2020-2021 following the commissioning of its replacement, after which it shall be converted and retained for service and rescue purposes in respect to its successor. During March 2016, construction commenced on the new Bözberg Tunnel, which runs roughly parallel to its predecessor. It is a considerably wider and longer tunnel, being able to accommodate trains up to a height of . The reason for its construction is to better accommodate larger and heavier freight trains. The second Bözberg Rail Tunnel is scheduled to be opened during 2020. 1875 tunnel The tunnel forms a key element of the Bözberg railway line, carrying a pair of standard gauge () tracks underground along a distance of .

Rapid Transit
Rapid transit or mass rapid transit (MRT), also known as heavy rail or metro, is a type of high-capacity public transport generally found in urban areas. A rapid transit system that primarily or traditionally runs below the surface may be called a subway, tube, or underground. Unlike buses or trams, rapid transit systems are railways (usually electric railway, electric) that operate on an exclusive right-of-way (transportation), right-of-way, which cannot be accessed by pedestrians or other vehicles, and which is often grade-separated in tunnels or on elevated railways. Modern services on rapid transit systems are provided on designated lines between rapid transit station, stations typically using electric multiple units on rail tracks, although some systems use guided rubber tires, magnetic levitation (''maglev''), or monorail. The stations typically have high platforms, without steps inside the trains, requiring custom-made trains in order to minimize gaps between train a ...

Tram
A tram (called a streetcar or trolley in North America) is a rail vehicle that travels on tramway tracks on public urban streets; some include segments on segregated right-of-way. The tramlines or networks operated as public transport are called tramways or simply trams/streetcars. Many recently built tramways use the contemporary term light rail. The vehicles are called streetcars or trolleys (not to be confused with trolleybus) in North America and trams or tramcars elsewhere. The first two terms are often used interchangeably in the United States, with ''trolley'' being the preferred term in the eastern US and ''streetcar'' in the western US. ''Streetcar'' or ''tramway'' are preferred in Canada. In parts of the United States, internally powered buses made to resemble a streetcar are often referred to as "trolleys". To avoid further confusion with trolley buses, the American Public Transportation Association (APTA) refers to them as "trolley-replica buses". In the Unit ...

Light Railway
A light railway is a railway built at lower costs and to lower standards than typical "heavy rail": it uses lighter-weight track, and may have more steep gradients and tight curves to reduce civil engineering costs. These lighter standards allow lower costs of operation, at the price of lower vehicle capacity. Narrow gauge thumb , right , 250px , Restored Molli railway at Kühlungsborn, Mecklenburg">Kühlungsborn.html" ;"title="Molli railway at Kühlungsborn">Molli railway at Kühlungsborn, Mecklenburg, Germany () In countries where a single standard gauge is dominant, the term light railway does not imply a narrow gauge railway. Most narrow gauge railways operate as light railways, but not all light railways need be narrow gauge. After Spooner's development of steam haulage for narrow gauge railways, the prevailing view was that the gauge should be tailored according to the traffic: "''The nearer the machine is apportioned to the work it has to do the cheaper will th ...

Life-cycle Cost
Whole-life cost is the total cost of ownership over the life of an asset. The concept is also known as life-cycle cost (LCC) or lifetime cost, and is commonly referred to as "cradle to grave" or "womb to tomb" costs. Costs considered include the financial cost which is relatively simple to calculate and also the environmental and social costs which are more difficult to quantify and assign numerical values. Typical areas of expenditure which are included in calculating the whole-life cost include planning, design, construction and acquisition, operations, maintenance, renewal and rehabilitation, depreciation and cost of finance and replacement or disposal. Financial Whole-life cost analysis is often used for option evaluation when procuring new Asset, assets and for decision-making to minimize whole-life costs throughout the life of an asset. It is also applied to comparisons of actual costs for similar asset types and as feedback into future design and acquisition decisions. Th ...
