Thanks Larry. I have tried the 9v adapter. Regarding tampering with the RCX
etc I would definitely be out of my depth and wouldn't want to risk damaging
them.

Thanks again. You understood me correctly and "we" have posted in the same

propellors. I was hoping to be able to control the power input to the RCX by
using the dial on the regulator - clearly that would be way too simple. :)

I appreciate your help! I will do some searching. It is about time I got into
LEGO trains so hopefully this is just the beginning.
