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.)
