Mr. Bach-man,

How many road #'s are available for the BN SD40-2 series locos?  I have 7845 and 7849 currently and am looking at getting a couple more.

Thanks

Thank you for the all the info.  I guess I am used to having to have things perfectly matched for my job that it has carried on to railroading.  I will try to play with CVs to try and tweak the locos. 

Bach-man,

Both locos were purchased in the last 6 months.  Also, the native DCC loco is quite a bit louder than the loco that was DCC upgraded.  Is it possible that I have a drive train issue on the upgraded loco?

I have two Bachmann DCC locos: 1 purchased w/ DCC and the other I upgraded to DCC.  They are both SD40-2s.  Is it common for the 2 locomotives to run at two different speeds even though the controller is indicating they are both running at the same speed?  I have them both set up for 128 speed steps.  I am using a MRC  Prodigy Express DCC controller.  One loco can be set to 50 (native DCC loco) and the other (upgraded DCC loco) to 50 and the native DCC loco will catch up to the upgraded engine in about 10 laps around the track.  Any suggestions?

Also, where can I find a list of all the Bachmann supported DCC CV#s and what each one of them do?

Thanks
