I have looked at alot im just limited on space, 43x54 inches so kinda limits me but i go with what i got then later turn my shed 8 ft x 12 ft into train shed and go all out on it this will be a good learning project . thinking of n scale next in my computer room but that will be down the road.
i would not use plaster of paris for that. instead several matches/square dowels adjusted to support but not lift the hanging track more. then fill them with the tiny foam chippings of which i think you have a garbage bag full and/or joint compound/ drywall mud(the dowels become your guides for the perfect level) - much easier to sand.
plaster of paris will be hard as rock. and noisier. and more expensive actually
also before you do that , verify your trains pass over this hill without scraping their plows on the bottom or cars uncoupling on the crest
oohh!!! also don't forget to plan for expansion. it seems like you might have some room on the right (i'd put a turnout leading outside instead of that tunnel)
yea it plows or scrapes im thinking of taking incline out or buying a kit to do one just caint get the foam like i want it and im thinking or a cork road bed i like the look of having a road bed. who knows where it will go im still playing with it.
it is generally not recomended to do grades in such small room. but if you have to have it, go ahead. i oculdn't have lived with flat layout. from my limited experience grades are about gradually increasing and decreasing and on your picture they do seem a bit abrupt. i wouldn't go for kit. fine tune your slopes with various temporary risers - toothpicks, match sticks, dowels etc.
roadbed is going to help the smoothness, i really like mine. but make sure your slopes work first.
took the slope out added another mountain in that corner . I also but down roadbed today i went with the foam kinda was told will make it quiet and a little easier to work with, time will tell how it works out . I figured it try since it is my first layout and next time i wil know more .[URL="
had a problem on one of the turn outs,should have been a right hand turn out i used a left the S shaped curve keeps derailing my cars. The loco will go around this but my cars wont.I went to local hobby store they are out of right hand turn outs so guess I'll have to wait to get one.Well I'm hoping it fixes my problem.got some painting done and added a little lake .[URL="
