| 词条 | Slip coach |
| 释义 |
A slip coach or slip carriage is a British and Irish railway term for passenger rolling stock that is uncoupled from an express train while the train is in motion, then slowed by a guard in the coach using the brakes, bringing it to a stop at the next station. The coach was thus said to be slipped from its train. This allowed passengers to alight at an intermediate station without the main train having to stop, thus improving the journey time of the main train. In an era when the railway companies were highly competitive, they strove to keep journey times as short as possible, avoiding intermediate stops wherever possible. {{TOC right}}OperationIf the express was on the centre track the coach was stopped short of the station and a shunter would move it to the right platform.[1] Some trains would carry a number of these coaches to be slipped at different stations, and sometimes more than one coach would be slipped at one particular station. In some cases the coach would, after stopping at the intermediate station, then be attached to a branch line train to proceed to the terminus of the branch, so passengers from the express train for stations on the branch did not have to change. Special coaches were built for slipping, usually composite, containing accommodation of all classes, and would also contain a small brake section where a guard would operate the brakes and where parcels could be stored. To reverse the journey, the passengers would board the slip coach at the intermediate station, which would then form part of a local train to the next station on the line where the express was scheduled to stop, and coupled to the express train there to be taken to its destination. HistoryThe first certain example of this practice being carried out was at Haywards Heath on the London, Brighton and South Coast Railway in February 1858. In 1914, almost 100 cars were slipped daily and there was a peak of 200 working slip cars.[2] Improvements in the acceleration of trains, the introduction of fixed multiple unit trains, and the high cost per passenger of operating slip coaches, meant that the operation had mostly died out by the mid-20th century. The Southern Railway abolished the practice in April 1932 with the electrification of the Brighton Main Line.[3] The last two slip coach operations on the London and North Eastern Railway were out of London Liverpool Street in 1936. These were the 6 p.m. which slipped coaches for Waltham Cross using old GER 6 wheeled slip coaches and the 4.57 express to Clacton on Sea which slipped a couple of coaches at Marks Tey for Bury St Edmunds using a bogie corridor slip coach of modern design, with a corridor "trailer". The very last slip of all was on the Western Region of British Railways at Bicester North on 10 September 1960. Slip coach has widely been replaced by dividing trains where for example an 8-coach train would split in 2 portions e.g. a portion to serve a main line and the other to serve a branch line spurring off the main line in question. Dividing trains are common in Southern England where there are many commuter lines. In fictionIn the 18th season of Thomas & Friends, three slip coaches from the Great Western Railway are introduced, and belong to Duck. In Chapter 15 of A Coffin for Dimitrios by Eric Ambler, the protagonist mentions having booked a seat on the Athens slip coach of the Orient Express. See also{{portal|Trains}}
