Do the make bridges for curves. I want to do a tunnel under a high point and it is on a corner. LMK Joseph
I do believe there are some kits out there that can form a curved bridge…check the walther’s catalog…there is also a Kalmbach publication called "Bridges and Trestles which has an article in it to show you how to build curved bridges from nothing more than some plastruct beams, evergreen styrene strips, and N scale girders…I built one for my HO layout using the N scale deck girders and it came out pretty nice…Chuck [:D]
One of the European manufacturers makes a curved girder bridge but I do not recall the radius. US practice in nearly every case is to make the bridge elements straight and curve the track on top of them so if you used a series of straight lines to make a curved section and then drew a curved line on top the curved line would represent the track but the straight lines would represent the bridge.
Thanks for the info Joseph
Microengineering steel viaduct would work, a little kitbashing and/or girders. You may want to look into Central Valley and possible use of their tie/ track system.
