Help! I'm a complete newbie, trying to rehab some HO trains I had as a kid. Just purchased a new Bachman locomotive thru the mail (DCC -- but supposedly compatible with old DC Atlas setups). It won't run. It's light flickers a bit and it makes a noise but it doesn't power up. Although the transformer is old, I know the track/electronics are okay, b/c I got one of my old Athearn locos to work fine. Is it possible the new loco needs more voltage than the 12 volts the transformer supplies? Or do I need to do a different wiring setup other than having just the two wires coming from the DC port? Or is it something else? I'd greatly appreciate any help ASAP as I'd love to have that new train work for my son under the tree tomorrow
