One with a motor.....
Two motors even better 
A dummy is essentially a very heavy car, you need pulling power.
(this is in the tinplate section, Williams made tin? Mistake I assume?)
What type of dummy? GG-1, A or B unit, calf, etc? I'd Match them right.
A hood unit MU? Go nuts.

there may be others, but Williams reproduced Lionel standard gauge 9E and 381E locomotives at least.
Thanks, just learned about those recently, then forgot already.
Searching quickly, I struck out yesterday, but remember now, that's where it began was 70's tin before O, and TCA had a page or two on those.
Its not exactly like pulling cast trucks that are still geared, but dead. But same principle, a heavy car. Assuming power isn't an issue, the one with the lowest mounted, shortest wheel to coupler mount & coupler length should pull smoother with less string-line side forces. Pilot and trailing wheels do the same, being light they sometimes need to be sprung/limited more against string-line ride up when double heading with a heavier dummy (in other gauges). A longer wheelbase usually helps limit heavy nosing up and down too.
I'd likely match any steeple or box cabs up..
Got a loooong tunnel? 
A bunch of short ones.
A steam, or even diesel dummy, for an electric to tow, would be a fun twist. All you really need to do is yank a dead motor out of something and maybe fab a coupler some.
No tunnel? "Clean air zone, 'cept the ozone" 
.
Most of what Williams sold had dummy frames to hold the wheels. Need more info from MADMAX before we can point him in the right direction. Is it tinplate, is O or Std, what engine number?

My Williams 408 has 2 Super Motors activated by a modern E unit. The installation was prior to my ownership. I think Hojack can enlighten you fully on Williams SG. I recall him telling me that Williams eventually offered their own can motors and chassis for their SG engines.
Here's the complete Williams State set, offered I think in 1978?
