Hi, i just bought my first DCC controller. The Bachmann EZ command controller. I programmed my two DCC locos to the controller but running my old DC locos are bothering me. So when i place the DC locos on the track they humm really loud and their lights turn on super bright~ should i be worried? Another thing, i have some Amtrac cars that have lighted interiors. Is it ok to run these light cars or should i open them up and disconnect the wiring to their lights?

- Here is a link to the Amtrak cars, hopefully thats enough info on the lighting

-here is my other DCC loco. (bought it used, has a dcc installed. Mines bigger than the one here though???) I'll open it and look around. I think its not Bachmann.
