Hello folks, been away for awhile.

Does anyone here own one of the new 89' Colorado Rail full domes? Was wondering about it being able to negotiate smaller than 22R curves. Bachmann recommends a 22R minimum, but wondering if that could be pushed to 18R?

And just curious, does it use the same coupler mechanism as the old full dome, that turned with the trucks?

Thanks in advance 

I have a new Bachmann DD40AX "DCC on board" on its way, and wondering if I can put it on my DC layout immediately or if it requires making an adjustment to the decoder?
It is advertised as dual mode, but not being DCC-savvy not sure what is entailed.
Thanks
