Are trains built on the track or built and then placed?

Question

When a train is buit, do they build it on the track or do they build them somewhere else and then move them to a track?

Answer 1

well they build them somewhere else like every cart is build separately then they put it on the tracks and connect them

hope that answers ur question ;)

Answer 2

They are assembled on top of a track once the wheels are attatched.

Answer 3

Trains are built in train yard, according to where the cars will be set off, First car/s are set off closest destination, and so on. Or another way to put it is classified in the yard.

Answer 4

They are built in pieces, then brought together onto an assembly track and built.

Answer 5

Both. First the trucks are placed on the rails, and then the car is lowered onto them.

Answer 6

Nope, they build different parts of it all over the place.    The basic structure of the carbody is built away from the rails.  The parts of the wheelsets are built away from the rails.  

Then the wheelsets are assembled on the rails,  pushed to a place where the carbody can be set on top of them, and the carbody is dropped onto the wheelsets with a lift or crane of some kind.

Then the carbody, on wheels, is pushed on rails somewhere else to have finishing work done.  At the very least brakes are added, and on a passenger coach this is probably when windows, interior trim and seats go in.

Often they will put the car on temporary "shop trucks", which are wheelsets that are cheap and not the proper thing for the car.  That's just for handling it around the shop, later on they'll jack the car up, roll out the shop trucks and roll in the proper trucks.

Wheelsets are called trucks in the USA, bogeys in the UK, and some French word in France.

Answer 7

They are built in pieces, then assembled together in a special workshops - at least they were, when we were still building them in Britain!

The tracks run inside these works -which have names for the different stages involved, like 'the erecting shop', 'paintshop', etc etc. As someone mentioned above, bodies and parts are lifted onto the wheelsets (bogies) by internal cranes, which run along rails fixed high up in the building and are strong enough to move complete trains in one go.

So yes, probably 'both' is the answer -the final stages are certainly on-track.

Answer 8

no in the yard and then movd to the track.

long time way to do this
