John Armstrong commissioned layout design. Wait! Too much linguini. Oh well. Sorry John but I did explain this issue. Had to simplify but a more usable plan resulted. Early member of the LDSig. SP based layout in bespoke carpeted track lighted charcoal painted high ceiling room. Too many interests to ever finish the darn thing. 400' code 83 Shinohara spline mainline. SwitchMasters. CVP DCC. iTunes. Lightoliers. Kinda the usual.
