I'm relatively new to all this so please bear with me.
How do I build a bridge on a bend? Do I have to build from scratch or
are there any kits (or even readymade)? I can find lots of straight
bridge kits but nothing on a curve. Oh, and I want a bridge, not a
trestle. I think I'd like a large radius if that has any relevance.
Well it depends on the type of bridge. Girder bridges cannot be built
'bent' so they go round corners in a series of straight lines. They have to
be wider than straight bridges because the track will be curved on the deck.
Stone, brick, and concrete bridges can be built curved and there are plenty
examples around. I'm afraid you are not going to find any kits, so
scratchbuilding is your only course. I have a large curved viaduct (the
famous one at Calvine on the old HR, done from the original drawings) on my
layout . This was made in 4mm ply with the internal abutments made as solid
wood and the deck also 4mm ply, with 1/16" ply on the insides of the
arches. The external abutments (fake Scottish castellated towers) were added
after assembly and were made by turning them on a wood lathe and sawing them
in half. The ply was then covered in Plasticard stonework from Wills with
hand laid up stones on the towers. If you would like to see pictures email
