It is advertised as the A and B unit are both supposed to be powered. I have it printed out. When you order a product, I see no reason to have to take it apart, fix it, oil it, or whatever. This to me is a reflection on the company that makes the product, what is a consumer paying for?
Here is your new TV set, oh by the way, you may have to take off the back and change a wire or two if you need it to work. What???
Collectables Today are not disputing the fact that the B Unit Engine are supposed to be powered. The second B Unit is not free wheeling, I have cleaned the wheels, cleaned the track, my other train runs fine, the Bachmann product does not. I am just frustrated, a person pays good money expecting a quality product. I probably will take it to a hobby shop and see whats wrong.
One other note, I have a dummy unit on another train, the B Unit Engine for the Bachmann is equally as heavy as the locomotive, I don't believe dummy units are weighted this heavy. But thanks for the input people, I do appreciate it, and will appreciate more input if anyone has any. Thanks

I purchase an HO scale NFL Express from Collectables Today and have received everything needed to run the train. First dillema, Unit B was not working at all, so Engine A could barely pull it, and cannot pull the additional passenger car. Collectables Today mailed me a brand new B Engine. Dillema 2, that engine does not work either. Not even a hum from B Units. A Unit can barely pull B Unit again. Comparing the F7 A from Bachmann and an F7A I have from Athearn, I have no problem pulling 7 passenger cars with the Athearn. The Bachmann F7A  will not pull more than 3 cars and throttle has to be wide open. I am very disappointed in this train set because the Shells are painted great! But not impressed at all with Bachmann engines. The F7A Unit sounds like its scraping as it goes down the tracks.
Anybody else have similar problems with the sets made by Bachmann? It was a beautiful collector set, but I am afraid I will have to send it back and have them refund my money.

It is HO scale, I tried to spread the sides a bit, but the shell won't slip off. I hate to monkey with it too much, it is under warranty still.

I have an NFL Express Set made by Bachmann, sold by Collectables Today. The set comes with an F7A and B unit. I believe the "B" unit is supposed to be powered, it is very heavy in weight (same as A unit), but the wheels are free wheeling, unlike the A unit. The A unit barely has enough power to pull the B unit along with one passenger car. Does anyone have any suggestions as to know if the "B" unit is supposed to be powered? I can't seem to get this question answered from Collectables Today, but they are sending me a new "B" Engine. I have a feeling I will receive the new engine but have the same problem. Can you tell me anything about these train sets by Bachmann?
