Transformer to run conventional Williams?

Your xformers will do just fine but to run Williams locos at slower speed you must change the wiring to the dual can motors from parallel to series which is easily done.

Yes, agree with Wild Mary. Your issue has less to do with the transformer model/type, and more to do with the  fact that Williams locos run like jack rabbits with the dual motors. They're great trains but they do scoot.

 

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

TCA, LCCA

I have used all types of transformers with these engines and have had no problems. If the track is level, they will run reasonably slow, but not at a snails pace like Lionel & MTH with cruise control. Great engine, my scale GG1 pulls about 30 cars without a problem.

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.

Also, the Williams Tru-Blast sounds will not activate/operate properly under about 6 volts.

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?

I use the diode method,described here

Another fine product of the Cleveland Public School system.

A nice site to visit is J&C Studios.

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.
