I need advice on bridges for my layout. It's 12' x 21' I'm using a 6" by 1/2" ribbon plywood base. with corkroadbed on 2" centers. I've used typical L-girder construction for the benchwork. Now it's time to place the bridges. I'm anticipating 9-12 bridges. ranging from 8" to 18" in length ( ALL DOUBLE TRACK ! ) 1 18" straight 1 18" curved 20*/22* radius 7-10 8"-12" straight The pike is Pen. Circa 1875-1920 so I can use a variety of styles. Any sugestions for sources for double track bridges? Where should I make the cuts in the plywood to allow just the right space for the bridges? should I place the track down first or place the bridges first? I will probably build all the bridges first. Then cut the plywood to match each bridge. Place the retaining walls, place the bridge then lay the track. Or should I get the track running properly 1st then then cut the plywood and drop in the bridges? HELP!!![?]
