All sorted. Looks like seller converted to DCC!

Thanks.

If that is the case I can run it DCC on a separate track for now. I will try later. Thanks.

I started On30 three years ago but my locos have been in storage since. Today I set up a test track and ran my two Shays  (non DCC). The Colorado model was fine but the Pocahontas won't move. The light blinks. Nothing happens.

Any ideas? I bought from eBay I think and have no records.

All I can say is that the Pocahontas has more chips in the rear compartment that than the Colorado so is it possible that it has been upgraded to DCC?

Thanks
