Really nice work Ken.
BTW, pertaining to off level benchwork:
I had contemplated putting a section or two of benchwork at an angle and placing the track base on short risers set to hold level track as is done sometimes in the smaller indoor scales. Then perhaps with short shelf like runners to hold major scenery elements from sliding have a “track built into the side of a slope look”. I think concrete would work to hold scenery in place and with a bit of retaining wall/cribbing and maybe a short section of bridge or trestle across a gully or two it’d make a neat scenic attraction for a raised railroad.
Just an idea I never got around to trying like having trains fording beneath a real water stream as happened on a couple of actual logging lines. Very possible now with battery power although maybe a bit unnerving for those not used to operating in a bit of rain.
Anyway enough digressing. Heehee! Great job you’re doing Ken and I really enjoy the pix.
