My diesel locomotive stops periodically on the track.  If I turn their speed control of all the way it takes off very fast.  Why does it stop sometimes on different parts of the track.

There are three PCB's for the HO GP40.  What are the reasons for this?

PCB (HO GP40)
board #H601x-PCB01
Model: 6031-PCB01 REV-B

PCB (Old Model) (HO GP40)
Model: 63521-PCB01 REV-A

PCB03 (HO GP30/GP35/GP38-2/GP40/GP50/ Universal)
Model: H601X-PCB03

P.S.  I tried to upload pictures but it said the upload area was full.

What is the reason for the GP40 motors that have resisters and those that do not.

A use posted that

"...If they are DCC and used, the prior owners may have programmed different performance variables (CVs) into them. If that is the situation, and I must admit that I suspect that is the case, start by returning all of the locos to their default CV values. Then you can make minor adjustments to obtain consistent performance characteristics."

Do I still need to be concerned about CV value if I'm only running them on DC?  If so how do I reset the CV to factory default?

Biggest difference I see is between DC vs DCC.  The last locomotive I bought was new DCC, I only have DC track, and it ran a lot slower even after break-in.  I replaced the circuit board with a non-DCC one and it works fine now.

Good idea about breaking in two locomotives coupled together to help them run at the same speed.

I would like the sound to come from different areas of the track: depot, construction, power generator, etc.  These sounds would be activated by a push buttion switch on my console so they would not all be on at the same time.  They have to be loud enough to be heard over the train and I would like the sound to come from that area of the layout: depot, switching yard, etc.

Will let you know what I come up with.

I want to record and playback various train sounds: whistles, crossings, conductor, etc.  On my control board I want to have different buttons to activate these sounds so if the train is in the station the conductor would talk.  Train at a crossing then you would hear bells.

I thought I found a good solution using a battery sound recorder device then mounting these near the point I want the playback.  Problem was that these devices are not loud enough and get drowned out by train.

Does anyone have advice?  I don't think a CD or USB player would work because I want short clips controlled by buttons and mounted in different places.

Thanks

All are DC new Bachmann locamotives

I've bought three Bachmann HO Locamotives, GP-40.  They all run at different speeds and some a lot different.  Is this normal?  I would think the same manufacture and model would run pretty close to each other.

Thanks, Pat

I need to replace the motor in my GP40 locamotive.  I was on Micro-Mark's site to by a truck tuner when I saw their motore.  Can this go in my GP40?

Also Mico-Mark gives details demensions and Bachmann doesn't for lots of their products.  I wish they did.

Thanks, Pat

Thanks for all the good advise.  I'm going to buy a HO Truck Tuner from Micro Mark.  I was able to very lightly grind the tips down and they work much better than the plastic ones.

Thanks, Pat

I want to replace the plastic wheels on some of my cars with metal ones.  I bought 33" wheels from Bachmann and the are too long even for Bachmann's cars.  The axles are longer and more pointed.  What do these fit?  Can I modify them to fit my cars?

Thanks, Pat

I need to order more couplers.  I want the standard ones that come on 40 ' stock with the springs.

What part # do I order?

I"m looking for a dummy engine to match the GP40 BNSF one I have but can't seem to find one.  I've searched the internet and can find other dummy engines but not this one.  Any ideas?  Could I get the BNSF shell and mount it on a matching length rolling stock car?

My wife got me a Bachmann starter set for Christmas and I'm hooked.  Great hobby.
