I hope this is allowed. I just recently got a Bachmann 4-4-0 Maryland and Pennsylvania loco and tender with DCC and sound. I also got an NCE cab. It is a great runner with great sound, I think. I can't get over the great control of speed at the low end. I couldn't find a video of this before I bought it so I thought I would share in case anyone has been wondering about this particular loco. I said 4-6-0 but it is a 4-4-0.
