Just wondering, if I was to assemble a 6020, 6051 and the appropriate feedback module would that enable me to run an automated shuttle service (like my old 6600 but digital)? I already have contact tracks on the line to sense trains and I can source an old laptop to control it.

I realise this would only support Motorola 1, but all I'd want on a shuttle service is directional headlights so that would be fine.

Thanks Fred - I guessed that it could do more but just wanted to check that it would cope with this.

6020 was the original digital central unit before 6021. It didn't have a control unit built in as you used either 6035 or the later 6036 for that, or alternatively use a 6051 and a PC.

Yep - only thing is I want to keep the 6022 for a main layout as it has the point control buttons. I often see cheap 6020/6035 pairings on ebay so if I bought one of those lots I'd end up with a spare 6020, which could then be combined with a 6051.
