Is it Possible...

Depends on how large, or strong the industry is. Ask yourself..... If you were them, Would this bridge be worth the money spent? and will we make back a profit?

hope that helped,

Well, the Railway makes good Money. And this is only One of the Many Bridges on the Line.
 
Looks fine to me! Look at what the Denver & Rio Grande Western or the Rio Grande Southern lines had to put up with. I think your route would be very good in a 3ft narrow gauge.

well, if time era is your concern...... I would say employ one of the meathods of the time....... created man-made piles of sediment to build up to your needed truss height
 
I'm not sure when the first all "Concrete" railroad bridge was built. I do know that from the beginning railroads were using both wood and stone to make some very large bridges and trestles. So if you were concerned with the bridge looking too "modern", you might want to try a stone one.

I wouldn't think any shortline would make a 2-track bridge anywhere other then perhaps a short one over a creek in a yard throat. Shortlines aren't supposed to generate sufficient traffic to justify a large 2-track bridge.

As for a trestle - give me the dimensions length -height, etc and I'll make one for you.

But how do you hide the track, rails, ties, handrailings, safety platforms, etc that might be part of the trestles on the bottom?

Ben
 
You don't have to. If a trestle is that big, they are going to need access scafolds, to repair the bridge timber, and you can make the track look lik metal support bands......
 
Interesting - I hadn't thought of that. I may have to run a small experiment.

Does this mean I don't have to make any more trestles, lol?

Ben
 
Ah yes, the Huey P Long, 10 miles up river from New Orleans. I've crossed that bridge approximately 20,400 times in my life.

It would really make a great model in its own right. It has rail yards on either side.
It's undergoing a major road traffic upgrade at the moment which will take the fun out of the terrifying drive across the narrow cantilevered road that currently crosses it. The railroad will remain the same except for some tweaking of the approaches.

Ben, if you're looking for a project, that could be it.

Some good comments here. You don't say what era that you're trying to model. This type of bridge wouldn't appear until the latter half of the 20th Century. It would probably be built in pre-cast sections which would then be moved into place and then post-tensioned. Forming an arch that extensive and pouring in place would probably be cost prohibitive. I'm not sure that a short line would go to the expense of such a design, but you're the chairman of the board and have controlling interest, so do what suits your fancy.
I'll be interested in seeing the finished product. I really love mountain roads.
