I have a question abuot DCC. I was first exposed to DCC at our last LUG meeting
where some of the motors had been modified. They were running 2 motors on the
track on different channels. Then we placed the two motors on the same channel
and placed them on my train (which requires 2 motors). The results were
nice...for a while. It ran quite nicely for maybe 10 minutes, but then it
started slowing in the corners...especially in two corners that were diagonal of
each other on the oval. It continued to go slower and slower until it came to a
stop in these corners and simply was acting like it had no power. Has anyone
else had this problem and what is the cause? Over heating?

| Were you running any cars with gray wheelsets behind your locomotive? The gray wheelsets have a few known problems, and can make a train come to a halt after a few runs around a track. It normally takes a few hours, but the heavier the cars, the (...) (21 years ago, 13-Aug-03, to lugnet.trains)

| Perhaps the speed of the two motors was mismatched for one reason or another. This would cause the two motors to generate more heat (because they're pushing or pulling against one another) and lead to a possible overheating situation. I've read (...) (21 years ago, 13-Aug-03, to lugnet.trains)

| I wonder if this is a caused by low track voltage? The DCC decoder does not put a steady voltage to the motor but rather pulses the motor with the duration of the pulses increasing for increasing speed. Although the motors are no doubt vulnerable to (...) (21 years ago, 25-Aug-03, to lugnet.trains)
