Can anyone help? I am fairly new to DCC. I have recently bought a Bachmann dynamis controller and having some trouble with getting Bachmann loco with Bachmann decoders to programme onto the rosta. My Hornby Loco with Hornby decoders work just fine. When I try to programme a Bachmann loco it does the little shuffle when programming but then nothing when you select the loco to move. My locos have all worked fine when using a Bachmann ez controller. Hopefully someone out there might be able to shed some light on my situation. Thanks in advance
