You might consider joining the Bachmann forums that specialize in Bachmann products. There are childrent there also. You need to add more information, do you have a DCC ready, DCC onboard, DCC with sound? Some Bachmann members run Bachmann DCC control systems.

The General Discussion or HO forum would be ok to post the questions for DCC.
