How many carriages are there in a train?

Answer 1

(English)There are eight carriages in a train.

(Mother Tongue)MRT train 里面有八个车厢。

It's highly variable, from country to country, operator to operator, service to service and rolling-stock design.

In the UK the maximum length for a locomotive-hauled passenger train is generally 12 coaches but many services operate with 2, 3 or 5-car electric or diesel multiple-unit (MU) trains. The HST is a high-speed express version of the MU, for long-distance journeys with line speeds up to 125mph.

An MU is a train in which the engine or traction-motors are under the floors of the coaches, which have an integral driver's cab at one end, and when coupled as three or more in the set, they are arranged as two or more powered coaches with intervening non-powered "trailer" coaches.

At one time UK branch-lines even used single-vehicle "railcars" - a powered coach with driver's cab at each end.

Answer 2

Transport 2010, the 10 year plan, published in July 2000, cites 10,400 passenger rolling stock "units". However, the source does not make it clear how many carriages there are in a "unit". For example, is a 4-car "multiple unit" counted as one unit or four?

That docucment provides no data on the number of freight waggons, which would also be of interest.

For interest:

Typically one carriage costs circa £1 million and costs at least £100K per year to run. If it last 30 years and if interest on the £million is at the Treasury Discount rato fo 3.5% then the annual payment to repay capital and interest would be£54K. If interest is set to 6% the annual payment woudl be £72K

Answer 3

well take the population of Britain and it would probably be about 1/2 of that
