Thanks for the info, Mark.
The train I am running is one of the Large Locomotives (Item#: KT105). I have 5
passenger cars (Item#: 10015), and 1 caboose (Item#: 10014). Total of 1 motor.
I was thinking that maybe I had too many cars on it, but it runs fast when it is
on the same side of the track as the regulator. I want to try the idea of just
stringing another power cord from the regulator to the other side of the track.
It seems like the most elegant solution I have heard so far. I just have not had
the time to rig up the cord yet.
Thanks,
Mark
