As I stated above I know how to use a bridge-cap and that to install one is a P.I.A.---however I did find 2 ways to do this

What I really wanted was a way to do this on the board (like cut out-add to-or change something)
since a bridge-cap is my only way at this time---I'll live with it
Thanks to all of you

Have you looked in the how to section on here? Look under Williams Trains, there is a diagram showing how to lock a Williams circuit board in forward or whatever.
Another way is to remove the circuit board and install a bridge rectifier and wire it to the motors in place of the circuit board.
Never run track power directly to a can motor (can motors are DC and track power is AC)as it will fry the motor.

I am well aware of all of the above however it seems that I'm the only one that has ever taken a Williams Peter Witt  trolley apart.
The circut board is a one piece intergraded everything ---installing a bridge-cap. in the unit is a P.I.A also to do this just
remove motor wires from circut connect  bridge to motor  and to pick up---The way the unit is constructed there isn't any room
Any way Thanks

I still just want to know how--- I know about switches etc--I want to know if there is a way to do this
Just what  would one have to do without an electrical engineering degree to do this
thanks for any help

Lee:
Yep--I don't know where "DEWITT" came from. Maybe it's the age thing.
Thanks

IS THERE A WAY TO LOCK THE TROLLEYS IN FORWARD ONLY
THANK YOU
