They work pretty well. I run my 12v "Grasshopper" Atlantic on 9v layouts. I have
to keep it at a kind of high speed, or the motor jerks and sticks (but that may
just be mine).
I use the quick-and-dirty method to make it go. It's powered from the top by a
wire that leads from a 9v tender behind it [1]. The contacts on the 12v motor
are taped down with blue masking tape.

Hope that helps!

[1] The wire has a 12v plug at one end, and a 9v plug at the other. It is not
necessary to destroy any 12v wires for this, since they simply unscrew from the
plug. Just unhook the 12v plug and screw it onto the end of a 9v wire that
you've cut in half.
