So... through NELUG, I have been involved in the Millyard project in the
SEE Science Center in Manchester, NH. The other day, we took one of the
engines off the track, and removed it's dead motor. The motor had died
because the springs had failed (no real surprise there). The motor was
the leading motor on a 4 car train, and the springs on one side of the
motor had failed. The trailing motor on the engine was fine.
Since I had this one data point (springs on one side of leading motor
failed before the springs on the trailing motor failed) I began to
speculate wildly, as any good scientist would... right? Here are the
questions...
Do leading motors on two motor engines fail more quickly than trailing
motors? (The folks at the science center had no information about which
motors were failing.)
If they do, would we be better off putting an unpowered truck in the
lead, follow that with a powered trailing truck, and a powered tender?

| (...) Chris- I've been thinking about finding replacements for the wheel contacts in LEGO train motors. At our May SCLTC event, I spoke with a visitor about the problem. The guys is a mechanical engineer and familiar with motor contacts and (...) (18 years ago, 20-Jun-06, to lugnet.trains, FTX)
