my locos wont go

[rickyd]

I have a Bachmann dcc ex command train set with 2 locos. I was in r/c for over 50 years, but injuries have forced me into a more passive hobby and I chose trains. Totally new to me. This past Tuesday everything was running like a swiss watch making 44 foot laps around the layout. Today, I power everything up, I can hear the motor starting up. NOTHING. No movement whatsoever from either loco. They are both factory stock, the set is new from just past Christmas (a gift to myself), but now I am facing a conundrum. Hopefully one of you experienced guys would be so kind as to tap into your memory banks and give me a clue. Thanks, Ricj.

Check the wheels on the locos; they dirty?
