Dear Brian , It feels very much like you are going thru a personal journey to find the joy and satisfaction you felt when you were a young modeller , and life was much simpler , instead your projects are turning out just as complicated as your museum quality , super accurate works of art you are so respected for . I think we are all with you on your journey , keep going please , you are the modeller who inspires me most , whatever you do ! PS. I think Kato will be the way to go for most of your projects , they always repay time spent on them over and over , I love the high quality crisp moulding of the ABS plastic and the quality engineering , and the newer finer handrails ( SD 38- 2 ) are straight ! 😁🙏🏻 I will always watch whatever you put out , with pleasure and great respect 👍
I will keep my fingers x'ed that the solution is as easy as 'back EMF', and tell you that you are not alone in bumping into such disappointments/frustrations ;) Further.. I've really enjoyed seeing someone do 'covered wagons', and Alcos (I also have always had an itch to 'upgrade' one of those weird-looking switchers (415 I think it is) and I'm rooting for these 'brick walled' projects .. fwiw.
I just realized something. That locomotive has the wrong truck sideframes. The EMD models that used the Blomberg style of trucks with the combination of square and angled journal box covers were the FT and F2. All subsequent models used the more modern style with roller bearings on all axles as shown as 9:00 into the video.
Brian. With ESU Loksound, make sure you release the "Independent Brake" (Shift F10). ESU programming has several brake CV settings (very comprehensive). With some ESU DCC files the Independent brake is on by default. The train will barley move until you release it. It sounds like a Back EMF issue. The motor should be fine. My GP40-2 is programmed this way. Try setting the throttle at Notch 5 or 6, then press Shift-F10 a couple of times (to cycle the "independent" brake ), to release the brake. This happened to me until I figured it out, I hope that helps. Cheers.
I'm 99 percent sure there is not a motor problem. You can check it by putting weight on the others models and see that it does not matter. Check old grease in the gears, possible it too rigid.
Didn't that motor come with that engine? You know? I had a flywheel slip on me once with your results. I put two new flywheels in and it's going now. Something to check. Good luck.
Late to the party! Those "last production" Atlas FP7's always had an underpowered motor. The same motor was used in Roco/Atlas S-2/S-4 models, and even those die an early death if they were run for a while at full load - aka, not just switching. They are overworked and generate heat. The heat weakens the magnets, making them weaker and hence hotter. It's a death spiral.
its not the weight of the model, is the plastic bushing spinning in the fly wheel if so a little acc should fix that or it the plastic drive shaft on the truck
I would almost agree with you IF the flywheel was actually spinning. It was not and when it did spin, it was very little and the model moved with it. Not very much, but it moved and then the flywheel would stop. The bushing is in solid. So much so that on the second motor, I broke one of the arms.
Your gears on the wheels have split and need to be replaced. They slip when you put weight on the wheels. Run fine when there isn't any weight on then.m.
Yes sir . I d put my money on that too.OR it can be dryed up grease in the trucks, that turn to glue. Either way, strip those trucks down. THERE IS NOTHING WRONG WITH THE MOTOR.

Thank you. This is a very kind and heart felt message. Thanks!!
Well said.

That's why I don't do DCC. Cheers from eastern TN

Thanks. I will give that a try.

No, you are correct. It was not a motor problem. It was a motor cradle problem and I have fixed it.
Hi Brian
Maybe the magnets need to be recharged
Ps. The model in the back is one of the SD45 demostrator units?
Brian, have you checked the momentum that may be built into the decoder? You may have to turn that off.
Didn't that motor come with that engine? You know? I had a flywheel slip on me once with your results. I put two new flywheels in and it's going now. Something to check. Good luck.
The flywheels are fine. Unconnected to the drive line the motor spins up just fine. Once connected to the trucks and in the frame, no movement.

i sold locos like those when i worked at a hobby shop for over 20 years, they where very good runners new

@@6axlepwr i believe the brass is glued to the armature shaft, the the plastic is pressed into the flywheel, again, i am recalling from memory
@@mikeslater75 you are correct.
I don't see how it would be the weight. The motor must be garbage.
Your gears on the wheels have split and need to be replaced. They slip when you put weight on the wheels. Run fine when there isn't any weight on then.m.
