Group,
I have 2 AZL GP38-2's, new, test run only.
I'm trying to run these together but, one locomotives couplers are lower than the others (front & back) and cannot mate.
How do I adjust these truck mounted couplers so are both at same height ?
Thank You,
Mr. Barlow

Is there anyway to take a photo? The couplers are truck mounted so both should align without issue. The only thing I can think is that maybe one coupler is loose in the coupler box which is causing it to drop. To check, pop the truck out of the chassis, and make sure the coupler box plate that holds the coupler in place is securely in place.

Check the bottom plate of the truck. It can pop off the little tab and let the coupler box droop down. It's pretty easy to snap them back in place.

As modelwarships was saying you can snap it into place ... I have a video showing how to snap it into place ...

Hi All,
I checked the couplers and tried snapping into place but, they seem snug.
I still have droopy coupler syndrome (DCS).
I took side by side photos comparing each locomotives coupler height.
Rob, can I text or email to you?
This particular locomotive (ATSF War bonnet freight scheme) looks like it was from an earlier run of the GP 38-2's.
I bought from Norms Train World, NE. about 3 years ago.
When I compare it to my other GP 38-2 (MoPac), the frame, motor and circuit board look different.
Both locomotives run faster (straight DC) in reverse then forward. I'm not interested in running DCC.
Sometimes, once warmed up, both locomotives seem to kick into another gear and go faster.
WHY the inconsistent performance ?
I've been modeling for 20+ years. Why can Atlas / KATO make N scale locomotives with uniform, right out of the box performance but this happens with AZL ?
Did I get 2 lemons ?
I have 5 MTL Z Scale GP 35's and they all run smooth.
I would appreciate some feedback and solutions to above issues.
Thank You
Mr Barlow

Mr Barlow, yes you can email me at rob@ztrack.com.
What controller are you using to run your GP38s? The controller maybe the reason you are seeing a stair step in performance.
Not lemons at all. The tolerances in Z scale are very fine. You will see quite a few discussions on this forum about locos running different speeds. This is all typical and expected. Things such as lubricate, frame tensions, contacts, truck gearing, etc all can come into play. What I can tell you is the more you run them, the better. They only way you will truly to do speed matching is DCC.

Hello Rob,
One of my locomotives, ATSF #2380 is eligible for the recently announced chassis swap for $40.
Can I also forward MoPac GP38-2 loco to you and get it "tuned up" ?
Thank You,
MB

MB please email me rob@ztrack.com. We don't have the availability to work on locomotives. But I still want to know more about your controllers and setup as well as see a photo of the coupler.

Rob, Track being used is a loop of MTL with Rail Power 1300 power pack (calibrated for Z scale Op's). Also have run these on a loop of Rohuhan track with matched Rokuhan power pack. RESERVE one (1) ATSF chassis with silver trucks please. I'll forward photos tonight. Thank You |
