I did run it on DC. After so much throttle the B unit will start the sound. Then with more power the B unit will start moving. The A unit however runs at a faster rate than the B unit, and slips it's wheels more so at slow to medium throttle.

Will the A unit run at a closer rate to the B unit with DCC. Is that a common thing with these or adjustable?

Thanks

Hi I just bought this Locomotive and was looking for information on it.  It is a Bachmann F7 A-B 


The B unit has a DCC board AE32034 looks to be from 2012. The A unit has K110526 on it.  


First thing I should say is I don't know much about DCC. Is this Locomotive just DCC sound and moves with  a dc transformer or does it move with a dcc controller?


Can you run it on just DC? 

Where I bought it said the bell and horn need programed. Could you explain that process?  


Being that the A unit has a motor itself not being connected to the B unit dcc boad makes me think it's just a DC Locomotive. 


Thanks for the help.
