Williams 5200 0-6-0, all brass loco. Any experiences?

I have on in 2 rail.    So I can't answer you curve questions.   In 2 rail my smallest curve is 48 inch radius and it does not hesitate on it.    The Weaver 0-8-0 would slow down or stall on that.

There is a chinese brand can motor, not a pittman.   It is mounted with a closed gear box with gear reduction to allow the motor to use a better torque range which improves slow speed operation.

Mine will easily pull 15 or more cars on level track.   My cars are free rolling mostly Atlas which are not lightweight

The detail is a little basic in terms of brass but very well made and as good as any diecast I have seen.

The B6sb represent the latest ones Pennsy built that came with power reverse and hense the smaller cab.

Traction tires are key with Williams brass locos. I have several of them, including the one you are considering, and none of them will pull much if tires are missing. O31 should be no problem for the B6.

I bought one new. Sold it and decided to focus on the NYC. From what I remember it was a good runner. Very well built. Can’t comment on 031 curves. But it should be fine. The one glitch it had. The roller mounted on the tender had an issue at times backing up. The arm would come in contact with the front trucks rear axle and trip the breaker. A couple of notches cut into the pickups arms solved the issue.

Here's the story on the Williams B6sb (#5200).  I love it.  Great runner.  Mine's been converted to TMCC.  It's rated for O42 curves.  The only reason is that the front coupler swing can't handle O31.  You can push (uncoupled) cars around O31 curves or you can run the engine coupled in reverse around O31 curves no problem.

Thanks for that info Bob.

Thankfully, I never push or tow cars with the front coupler.

Interesting, that all of the box ends I have seen say it is rated for 031 curves.

2-railer here - I have three, and think they are a "best buy" in O Scale.  Mine towers over a scale box car, and is larger than my CLW H10 Consolidation, but I am really happy.  I dare not say they are 17/64 scale, since that seems to make folks unhappy.  I converted one to the 701-style cab.  Two were converted to 2-rail; the third came from the factory that way.
