Thanks everyone for the info and the pdf.  Both units are brand new and would have thought they would run the same LOL.  I will give it a go and see what happens.  I looked and didn't really see a drop in decoder for these.  Digitrax wants me to solder in a decoder and I haven't had the best of luck on trying to convert some old DC locos to DCC.  So now I just buy them with it already installed.

thank Kewatin

What CV number is the starting voltage etc as well as the others.   I realize that it is basic but if i can get them the same it would be easier to do a consist function

Hey
Mister Bach Man, I have your F7A and B units in N Scale and one moves faster than the other when set to the same speed.  I wan't to change them so that they both run the same at the same speed settings.  Right now they don't and it makes running them difficult.

Thanks for the help.

I have to agree.  I got an old steam loco that was passed down when my dad died last year and I couldn't get it to run.  Sent it in for repairs and because they don't make that model anymore they are sending me a new loco for the $25 repair fee.  You can't beat that with a 10ft pole.  Thanks again Bachmann

I just looked up the spare parts and noticed that the motor for this is different.  Is that why it runs slower?

Hi I just bought a new S4 diesel loco w/dcc switcher item #63154, and after I programmed the road number in it, I put it on the track where i had to apply darn near full power to get it to move and it was moving really slow unlike the other bachmann locos I have.  Is this normal for this switcher or is there something wrong with it.  If there is please let me know so I can send it in to get fixed.  Thanks

Yes it can be done and there are plenty of you tube videos that show pretty much how to put a decoder in anything.  Dremel tool is your friend as it makes grinding off enough of the metal to get a TCS Z2 or any other small decoder in.  The split frame locos are actually pretty easy to do once you watch the video as I have converted about 6 of my DC locos to DCC now.  Oh you have to have good soldering skills as well because the decoder wires are like 30 gauge wire (really tiny)  The hardest part about converting to DCC is figuring out where you are going to mount the decoder plain and simple.  Some are easy others not so much.  good luck
