The Lionel TPC is the perfect controller for Williams trains. You can start out at 30% power and multiple units will start up synchronized with each other.

 

Any transformer/controller that starts around zero to three volts will do the job just fine without rewiring the motors, but may not start multiple unit diesels in sync.

 

In my opinion, it's about getting a good controller, not modifying the locos, and that is the opposite opinion of some others.

I run my Williams GP-9's with an MTH Z-1000 and have no problem.

Also run my Williams SD-45's with a post war ZW and have no problems.

With my Williams F-7 set I had to add another powered unit to pull a full set of six passenger cars.

My two cents on rewiring, if I rewired the F-7's to run in series a snail would have gone faster than my Williams engines. Maybe my power company has a lower voltage rating or cycle frequency that I am not aware of, so to rewire a Williams for series just won't work for me.

 

This thing about rewiring a set of motors is something I have stayed away from, and with the brand new WBB you kill the warrenty instantly if you rewire the motors or anything else.

 

FYI, I have not used a CW-80 with any of my Williams engines. Maybe that transformer puts out a higher voltage or something when used with a Williams engine, so a rewire might be a consideration with that transformer?

There have been several threads here in the past about re-wiring them.

I use the diode method,described here

I would try the diode method going to track power(inserting into the track between the transformer and lock-on power terminal first to see if you like that effect) rather than rewiring the motors in series, as you may not like the super slow effect.

 

One thing that happened by accident; I started a Williams GP-9 at wide open throttle with a ZW by mistake, and it sure took off, right off the track!! A few scratches on the side of my GP-9, but no real damage; nothing broke off and it still runs well today.

Was working on another engine and forgot to turn the power off before putting the plug back into the wall outlet.
