Around the room elevation changes

Elevation changes allow for tunnels and bridges. Decent, non-troublesome, grades usually require at least 10 to 12 ft of run to get 5" to 6" inches of rise/fall.

even that is >4% grade.  if you can afford the space 2% (1" rise for every 4' of track) would be my suggestion.  of course if you merely want some interesting elevation change without necessarily crossing over the same line, slight grades would be easier to incorporate.

you can have 2 types of elevation changes, one being the track descends and rises.

the other the land goes below grade.

one other thing to consider is the upper track crossing a lower track this also breaks up the 3 loop running.

best advice go out and find train tracks follow them via roadway you will see the tracks go up and down sometimes but more so the land is rising and lowering this might give you some ideas.

Yes, the grades pictured are 3.8%.    Stretch the run to 20' to 24' or cut the rise.  6" to 7" rise worked for the tunnel.

Bridges and tunnels, IMO, Great parts of a layout   Mike CT.

dobermann.....just to give you a heads up, I sent you an email today regarding your benchwork.      

                       thanks, luvtrains (Fred)

Joe, I just replied to your response. Don't know why my email didn't go through.

                   Thanks!

Got it. You have my comments. Hope it helps you.
