Anthony-
I’ve reported on this same subject before. The fundamental problem, viewed
from the top level, is that LEGO train motor assemblies are not reliable and
behavior can deteriorate rapidly and randomly according to usage, load, and
luck.
The good news, from characterizing and disassembling many LEGO train motor
assemblies, is that the problem is almost never the motor itself. The
problems come from bad electrical connections from broken/worn/bent wheel
pickups and from failure of the thermal protection disk. Since we do a lot of
DCC, we automatically remove the thermal disks when we take motor assemblies
apart to wire in the encoders. That leaves only problems with bad motors, and
we have only ever found 1 actually bad performer (dead, actually, until we
pushed in the shaft, and then intermittent). Believe it or not, I have better
success converting seemingly dead motor assemblies to DCC than brand new ones
out of the box!
(And, in any event, you can just send your bad performers back to TLC for
replacement at no charge.)

Forgive my ignorance, what is DCC?
I do plan on sending in my bad motor. I went back to my Santa Fe rolling stock
and found all of my observation car-style cars have horrible friction damage to
the upside down studs between the wheels, as has been reported by other people.
The damage on some of the studs is so bad that 1/4 of the plastic is missing off
one side of the stud. No wonder the motor died.
I’ve replaced all of those plates with tiles, so hopefully I won’t have to worry
about that problem anymore.
