Welded Rail

Is it possible to carry 80m of track (or welded rail) on say six flat cars, and the rail bend as the train proceeds through curves? if the answer is yes, some advice on how to achieve this would be appreciated. I am trying to build some rakes of waggons to carry either welded rail, or welded, assembled track.

Yes, welded rail will bend when transported. I have heard it comes in huge rolls also.

I have worked on a track gang for a local rail museum and I was told something that I never thought possible. The "track boss" said that when rail on curves is unspiked and lifted off the tie bed, it loses its curve in a few hours and becomes straight rail. I have also seen the rail flex and bend when jacked up from the ties. Rail is very flexible.

Another way long pieces of welded rail are transported is by dragging the rail behind the last car in a work train. Believe it or not, at slow speeds the rail dragging over the ties does no damage. Metro North does this on occasion when moving a long piece of rail.

One last tidbit about rail. If lightning strikes a rail, which happens a lot, the bolt of lightning can travel along the rail for more than a mile. Trespassers have been electrocuted and killed by coming into contact with a rail that was struck by lightning several miles down the track.
 
That would be pretty tricky. Each car would have to be attached to the rail product in order for the rail to stay tied to the car. Perhaps something along the lines of bendorsey's hicapcity car, which is put together in surveryor?

I think jmorty is trying to build wagons for Trainz, not for the real world ;)

Yes, I am familiar with all aspects of transporting welded rail, and fabricated track. I am trying to do this same exercise in Trainz, and quite frankly, don't know where to start.
I am looking for some guidance with this project

You can try that when you make the rail(s) out of invisible wagons of 1 a 2 m. long (no longer to get a good effect in de curves ), and place a visible wagon every x rail segments ; a wagon thats coupled only on one side ( thus with all the attachmentpoints close together ) . That wagon will break out far in the turnings, but you can see what length is possible.
thus : rrrrrrwrrrrrrwrrrrrrw.....

I was thinking about this last night. I'm not an expert at this nor am I a very good modeler. So here are my thoughts on this, and hopefully the "more informed" folks can then pipe in with there take on this.

1) You need to build the models with attachment points of some kind like the passenger cars have for people-models.

2) The product will have to be a meshed object of some kind, and not a spline I assume, and match up with some kind of attachment point on the cars.

3) When you set up the welded-rail train, this consist will actually be a single car with multiple swiveling bogies like Ben's high capacity car.

4) When the loads are placed on the car, or off the car, they will need some kind of line-side industry to hold them.

How to go about doing this? I couldn't tell ya, maybe the others can.

They're replacing the rail on a local line with welded rail so I got a picture of some that had been delivered.

It's a little hard to see, but it's the dark bar on top of the yellow carts. There seems to be one rail per string of carts, although I'm not sure why two wouldn't work as well, depending on the severity of the curves.
It would be nice if you could do a working rail car as a spline so it would flex on curves.:D

:cool: Claude

I kind of gathered that from the beginning. ;)

Anyway here's a nice collection of pictures of a welding train starting with the picture in the lower-right corner. These were taken on the Providence and Worcester.

It is possible if you use shorter wagons . I've used 6 m wagons ; you need 2 railsegments per wagon ( one has to be reversed ) .
The coupling is done between the railsegments , not between the wagons , so that when the train stops or start , the wagons move a bit, but you cant see that there are 2 segments coming together.
This is 3 x 130 m of welded rail :)

 
I am not sure on how to go about this! Does the track (load) bend when the train is negotiating a curve?

wow ive never heard of thaat
 
The picture is too small to see exactly how you have done this.
When the train goes through a number of curves, will the rail (load) bend, or does it pivot at each poin where the rail segments meet?

Thanks Moojgoo, now I can see it all.

markbin,
the picture looks great but I still have not worked out how to achieve what we see in the picture!
