Can anyone tell me what decoder I should use to add sound to Bachmann Ma & PA #6 W/Steel Cab - Richmond Modern 4-4-0 - DCC.
Thanks

I'm fairly new to the hobby and after playing with analog Thomas the Train locos with my young son, we have moved on to DCC. I purchased an EZ Command DCC Controller a few months ago and all was working fine. We are using the Bachmann -Your First Railroad Track Pack. Then a few weeks ago we noticed that both the loco (Bachmann ATSF 2121) and Diesel ( Bachmann B&O Chessie System 3139) only run at one speed (full speed). In addition, I have noticed that when I do not insert the power cord from the wall unit all the way into the controller, it sometimes works as intended.

Can someone please direct me to what we are doing wrong or is it a fault of the controller?

Thank you for you help!!!
