I think this is how you want to do it. A simple solution would be to
go to Radio Shack, and buy a couple large ceramic resistors. (not
sure the values you'd want, but something low). Then, take a normal
9v wire, cut it, and insert the resistors in line. Functionally it
would be the same as inserting a second motor in line, but with no
moving parts.
I suspect it may get warm/hot, with continued use, but it's designed to do that.
Hope that helps

| Our club lets kids run the controller for one of the lines when we do certain events (like, right now, with Detroit Festival of Trees), but we could use a way to forcibly limit the speed on the line that they're allowed to run. One way that's really (...) (15 years ago, 23-Nov-09, to lugnet.trains, lugnet.robotics)
