I have a GG1 Pennsylvania Railroad DDC engine. It makes the sound with my analog controller, but makes no sound at all with the DDC unit I have. The headlights does not even work. Both the engine and the controller are Bachmann products. Why won't they work together? The DCC unit is an "E-Z Command Control Center" Item # 44901.

It is E-Z Command Control Unit, Item # 44901.

I might also add that I have a Bachmann HO GG1, Pennsylvania RR engine. It makes the engine sounds with my analog controller, but it does nothing but run around the track with the DDC unit. The lights don't even work. As you can see, I am not a happy camper with this unit. It's supposed to do more, but in reality it does FAR less.

Do any of these units well, or do you really need to buy something that is much more expensive?

I have a set of Bachmann Amtrack cars and a Bachmann DDC Amtrack engine. The couplers do not line up properly so that I can run it on Bachman E-Z Track around a Christmas tree. I have worked to get the track as flat as possible, yet I always have problems. Why can't the couplers match up on equipment that is made by the same manufacturer? It is really frustrating.

I own a Bachmann DDC transformer and I am very disappointed with it. I use it at Christmas and have owned it for going on three years. I have NEVER been able to switch a "DDC inside engine" from the #3 factory setting to any other number. A factory representative at one of the train store shows told me to use the "Function key," but it still does not work. I don't know what to do. Can someone give me step by step instructions?
