and is mainly concerned with the overhaul and daily servicing of their fleet of High Speed Trains and also the DMUs used on local services. The depot code "LA" is used to identify rolling stock based there. After sixty years as a steam depot, servicing locomotives used on the Exeter to Plymouth line that runs past the shed as well as local lines, diesels started to arrive in 1958. A diesel depot opened in 1962 and was expanded in 1981 to accommodate the High Speed Trains.


History


Steam shed

Laira was the location of the temporary terminus of the South Devon Railway from 5 May 1848 when a small engine shed would have been provided. With the completion of the line to Plymouth Millbay railway station on 2 April 1849 a new shed was provided there and the facilities at Laira dismantled, although it remained a junction for the branch line to Sutton Harbour which was

in the middle. 28 lines radiated from the turntable for stabling locomotives and it was fitted with a 20-ton hoist for lifting locomotives (a 35-ton one was added later). A small railway station known as Laira Halt was opened on the adjacent main line on 1 June 1904 but closed again on 7 July 1930. The shed at Millbay closed in 1925 and in 1931 a new 210 by 67 feet (64 by 20-metre) four track shed at Laira was brought into use just south of the original roundhouse, funded by a government loan under the

locomotives started to appear in 1958 and were at first accommodated in the New Shed alongside steam locomotives until the diesel maintenance depot had been finished. The Laira marshalling yard alongside Embankment Road was closed in 1958 to make room for carriage sidings and a new diesel shed, which was fully opened on 13 March 1962, although parts had been in use since 1960. Laira was designed for the servicing and heavy maintenance of the diesel-hydraulic locomotives favoured by the

(the depot became well known as the final home of the 'Western' Class). It also handled the local diesel electric shunter and DMU fleets, although servicing of the latter was done initially at Belmont sidings at Millbay. The diesel shed was in reinforced concrete and comprised three adjoining buildings.

changes. The central building was the Heavy Maintenance Shed; engines can be removed and repainting undertaken on the two roads, numbers 5 and 6. The final three roads were in the servicing shed on the eastern side of the site, where locomotives could be inspected and refuelled. There were covered fuelling points outside in the yard, supplied by a 45,000 gallon fuel tank. A small group of buildings house stores and a workshop for shed equipment and is situated between the main shed and the curve of the Sutton Harbour branch (now realigned to the west of the shed and known locally as the "Speedway"). Carriage washing takes place south of the shed at Mount Gould, alongside the line to Plymouth Friary. On 30 September 1981 a new shed, long was built on the site of the old servicing shed that can accommodate the eight coaches and two power cars of a High Speed Train set. Following the withdrawal of steam from the area in 1964, the roundhouse was closed on 13 June 1965 and the area used for additional siding space. This area was later modernised and fenced off in readiness for servicing the Nightstar

never materialised. After the replacement of High Speed Trains on London services, one road in the shed was leased to Hitachi to maintain the and 'InterCity Express Trains' (IETs) that replaced them. A number of Class 43s are still based at Laira to operate four-coach services to and . In Edinburgh, the depot at Craigentinny was no longer able to maintain CrossCountry's Class 43s as the space was needed by Hitachi for IETs so the 12 power cars and 5 sets of coaches were transferred to Laira.


Historic allocation

Up to the 1960s Laira had an allocation that consisted of a wide variety of Great Western Railway motive power, including 4073 'Castle' Class and 6000 'King' Class express passenger locomotives. The following lists give summaries for various years. During the 1960s and 1970s it was well known for its fleet of 'Western' Class diesel-hydraulics. The last of these were withdrawn in 1977, by which time
