Lovely layout, getting the trains running well, and the bridges for a clearance is the backbone of a good layout, once that is all sweet, and you like how it plays,then it is safe to do the scenic area, I like when people choose a specific geographic and era, I run loads of different. But prefer them to run in smaller matching sets, but use the fact my main station is in real life a preservation station allowing me to break all those rules

. lovely layout will look out for this as it progresses.
