It looks like Bachmann needs to update their "Parts, Service & Information" web page. There is a link for "Soundtraxx Decoder CVs", but it goes to a dead page on the soundtraxx website (

To remove the shell, simply spread the sides of the shell apart at the fuel tank and lift. Getting the pilot coupler through the pilot on an "A" unit takes a bit of twisting and finagling, but it can be done relatively easily.

Yes, the top piece slides up and out. Perhaps this will help -

Says the GP40 w/ sound is "shipping now" but I haven't seen any show up on etailer sites yet.

The motor lives inside the tender and there's supposed to be a plastic driveshaft connecting the motor to the worm gears inside the engine. Sounds like yours is missing its driveshaft. Depending on which version of the 4-4-0 you have, it would look like one of these -

Haven't tried it myself, but I think MTL 1128 is the one you want for that.

Have you tried contacting the Bachmann parts department directly? They sometimes wind up with oddball stuff that doesn't make it into the parts listings on the website (like from when people return defective locos).

Try a decoder reset (write 8 to CV8) if you haven't already. Same as rebooting a computer, it's always the first thing to try.

I agree with James, I don't think the shell would cause a short-circuit in and of itself (it being entirely plastic), but putting it on may be causing problems with the motor wires. How snug is the decoder installation? I could see the shell pushing down on the motor wires and maybe causing the decoder to move around and lose contact with the chassis if it's not tightly engaged in the chassis slots. Or maybe the shell is causing one or more of the wires to lose contact with the decoder. Are they soldered to the decoder or just pressed into it?

OK now I hope this doesn't open a heated discussion, but what do you recommend I use to "clean everything"?

I'm thinking Isopropal alcohol?

Isopropal does the job for me.

Mark, Have you ever tried some of those conductivity-enhancing coatings on those surfaces.  Some, like "Never-stall" are greasy, and might catch dust and still allow a stall.  But there is also "Neolube",which produces a dry graphite surface that conducts.  But, does that wear off?

I sometimes use conductalube for moving parts (like axle-ends). I've never tried Neolube, though.

Contamination happens sooner or later with every loco. Weather changes can accelerate the process (like if you live in an area where the humidity rises along with the spring temps).

Clean the track, clean the wheels, clean axle wiper dimples where the tender truck axle ends insert, clean the drawbar contacts where they rub up against the chassis post on the engine, clean the tips of the tender truck contacts and clean the contact strips inside the tender that said tips brush up against. In short, clean everything that transfers current  Grin

All of Bachmann's "DCC On Board" (non-sound) decoders have the same functionality. They have very limited features as far as speed matching goes -

I'd be surprised if you could get it to run even with a new motor. The nylon gears in those old J's are notoriously prone to shrinking and cracking over time.
