Ok will do later today

rrinker I still say it's a track issue. Finer models can be a bit more picky, but if they loco runs both ways with no problem through a 26" radius curve then 28" should be no problem. That loco should run at speed through 20" or less radius, actually. I suspect such things as the joiners not holding the rails in exact alightment, so there is a lip on the inside running surface in the middle of the curve, or there is a kink at the joint, or there is a hump or dip in the track through the problem curve. --Randy

tstageI think Gary answered the question:
I did not see that post. But it's still broke.

Well, I thought it was fixed. Runs around curves up reverse (cab forwrd) which is the way i ran it after I thought it was all fixed. I did run it both ways in the tighter curve 26”. When I run it forwards (hood first) on teh 28” radius track it derails about 1/2 way through the curve. Again no other loco had any issue on either curve.
GOT to be something with the trucks. Guess I neeed to take the shell off and look arround.
Henry,
I think Gary answered the question: The front truck wheels were slightly too close together and the rails weren't level.

It's not the track radius. Did you check if the wheels are in gauge?
Well that worked!
Front truck wheels were just slightly too close and the track was not level across the rails. Off level about an 1/8th of an inch. Now it flys through and crawls too.
Thans to all.
Ok one at a time I’ll Check each of the recommended actions. It will take me a while but I’ll get back with the results.
Thanks for the posts.
Nice Christmas present! I'm agreeing with what Tom told you, checking the wheels on the loco.
I found the best way to diagnose derailments is get my eyeballs right down on track, and slowly move the loco, or the car, over a trouble spot and see just what is happening. I've even used my optivisor to get a close look. Of course, this only works if it's on a section of track you CAN get that close to, without scenery, etc., being in the way.

If the track is fine, check for a binding in how freely the truck turns. Sometimes the wires lay under the shell in a way that shortens the slack needed to allow the truck to turn.
But if it derails on a turn, there is probably a dip in the outer rail compared to the inner rail. A stiff truck will find that dip easier.

When i have that happen i find a wire or something not letting the truck rock and track propperly. Run it without the shell and watch. Slow speed and push it through that area. Could also be something like the axles arent tracking because of flashing. I will have to try mine when i get home. Had them for a while. Just have not gotten them through the paint shop

Gary,
Check the gauge of the drive wheels of your RS1. Also check to see if the track dips in that spot of the curve. Could be more than one thing going on.
Just got an atlas Gold series RS1 for christmas and tried to run it arround the layout and it derails on a 28” Curve at the same spot in the reverse direction only. No other locomotive, steam, diesel or freight car or passenger car, 4 or 6 axle derails there. No Steam 060 or 282 or 464 derails. The NMRA Gauge shows the rails are the correct distance apart.
Any ideas?
