It might work better on AC - I don't care, it came with a DC power supply.
Lionel's job at this point is to fix it. I think I should send it to Lionel in the same packing container I sent PE loco number 1 to them in - that is of course, once I get loco number 1 back. I can start a collection of RA numbers to list on the box when I send them to NC
