I'm using code 70 rail for the main line and code 55 for the sidings. It will be DCC operated (NCE) and portable, though I'm not planning to move it far. If I surprise myself and finish this, I will complete a loop and a fiddle yard to operate the station prototypically.
The current state is this:
The rail has been laid with PCB ties used to maintain the gauge and the 6-foot. Points have been built, with the exception of the switch-blades. Platform is under construction, and the station building (from a kit - can't remember whose) and the signal box (SJM) have been painted in the stone scheme. I've laid cork road bed and the next step is to detail the rail, paint and glue down to the sleepers. These have been stained with dilute grey raven oil. A very effective weathered silvery/grey finish results.
More to report soon.
