Hi Don, I agree to what everyone is saying the rock moulds are pure awesome, going to be great when finished, I like the green steamy.
I am modelling the Tehachapi loop on my HO scale layout which is a garden railway set up.
The only scenery I will be having is the Tehachapi loop and working the tunnel 9 module. Where I am working on now is the bottom track that leads into tunnel 9, have the other cutting to do also, will leave that to a later date want the trains running first.
I will up date my post once I finish that section, which is in the OO,HO scale garden railway topic, under Tony M.
