The trouble with having a DCC test track in the office is it's started to grow already. If I prop the hi-fi and phone up on books I can get a nine foot run on top of the bookcases. The Rocoline pointwork I use for testing purposes has built in DCC point motors and all of the frog polarity issues are dealt with out of the box. It really is 2 wire stuff and before long a complete 3D layout plan has appeared out of nowhere.
The Bachmann Rats pictured have already had P4 wheels fitted and then removed again. I'm now thinking of popping them back in and throwing together an electric ironing board to run them on. Get a grip Jones!
