The 2-Bil is nearly done - here's a photo of the very rudimentary interior, which uses Preiser figures and the original Kirk seats (one of which is wonky and has since been stuck back in properly!).

I've also wired it up. I fitted Steam Era's wheels (as used in their Black Beetle) to the trailing bogies. These are only insulated on one side, so each trailing bogie picks up current from two of it's wheels. By soldering wires to each bogie frame and interconnecting the two coaches using a connector sold by Comet for loco to tender connections I now have pick up from both coaches. How well it will work in practise remains to be seen but hopefully the unit will never stall on points or dirty track..
