Let me begin by saying I know NOTHING about Williams stuff; but have been reading some of the recent threads with great interest. As you can see, it's sitting on an All Nation/General Models Pacific diagram, so it's indeed full size O. It has a 1/8"(?) plug coming out of the cab, on (2) wires; I guess this must be for the tender pick-up (?) I see a can motor inside...

Simplified valve gear, but over-all, a nice enough looking piece...I think. Is this suppose to be based on an ATSF engine? Anything else anyone can tell me about this?

I believe it was the 1982/1983 b&o pacific. The first brass loco from samhongsa imported by Williams. No flywheel motor and im not sure about a reverse or a seuth smoke unit. A basic brass steamer but a good start to upgrade and detail.

Thanks. Here are a few more pix:

Dunno if you can see it: this little "arm" is wired to one of the tender wires:

...and what is this black square thing for? It's wired to the  motor leads...

This has pick-up rollers for a center rail: is it supposed to run on AC or DC? Like I say, I know zero about Williams stuff...

This is the Williams B&O Pacific of 1984 as noted above.  I don't know much about the specifics of this model.  All my other Williams brass locomotives have a four wire harness that comes from the tender and plugs into the locomotive.  Two are AC for the center rail pickup and the neutral and two are DC for +/- poles for the lighting, Seuth smoke unit, and motor.  This one probably only has two wires as it did not have a reversing unit.  I'm not sure if it has a bridge rectifier in the tender or not?

I'd be curious to see more photos.  It has shown up on Ebay from time to time, but I'm not buying much 3 rail anymore.

Thanks. I picked this up sans tender, so I dunno about anything to do with that aspect of the model. I tested it on DC ( because I wasn't sure) and it "runs", although not very well. I got this strictly as a project, so it's gonna need some help, for sure! Seems to be fairly well constructed; heavy, solid frame.

I will be happy to take more pictures if it'll help...

Thanks to everyone so far. 

The only markings are:

"Williams    4-6-2    Made in Korea"

Re: the bridge rectifier. So I guess this has been modified to run on DC, even though it's set up for 3 rail...?

It appears that the front set of drivers had, at one time, traction tires, as they (the wheels) are grooved. The rear set still has 'em, as you can tell by the photos. Any chance of finding replacements, you reckon?

I don't think it's been disassembled for a LONG time, as I can't loosen the screws on the bottom plate to get to the axle bearings to lube. Suggestions?

As others have stated, this is the very first Pacific Williams ever made. The engine does not follow a specific prototype, but rather incorporates features from several different roads. The engine came with a lead weight you could insert into the boiler for added traction. Seuthe smoke unit. It was designed as a 3 rail AC engine, but likely built by a company that had 2 rail experience. No flywheel, so it stops on a dime when the power is cut. The original reverse unit (E-unit) was inadequate for the engine, as the motor draw (amps) was too high. So many of these have the E-unit removed and a hefty full wave rectifier installed. It will run, but forward only. (You have the rectifier.)

I have an engine and tender available for a reasonable amount. Contact me if interested (Email in profile). Note I am on the east coast, so plan accordingly for shipping.



"The engine does not follow a specific prototype, but rather incorporates features from several different roads."

If memory serves...actually it has a B&O prototype, and is not a bad model of it, if  not encrusted with details. I forget the exact B&O class or loco it follows. The basic mechanicals were used under their very early - non-Samhongsa - Wms J3 NYC Hudsons. All of these locos are rather delicate, but can be interesting projects, if their mechanical and detailing are acknowledged. They are handsome. I have never equipped one with an ERR Cruise Commander, for example, but I imagine that their running characteristics would improve.

I have one of these B&O's, but I can't lay my hands on it.

Update. I figured out the drive gear access; a generous application of clean grease really helped.

Questions: here is a shot of the air pumps:

air pumps you can see, they're mounted in opposite directions. Is this normal? Also...

Here is the lead truck: (get a load of the size of those flanges...! )

pilot truck

...the "arm" that connects it to the frame is attached solidly to the truck frame; there is no "secondary" pivot point. I don't think I've ever seen a pilot truck set up like this weird, or is it just me?

Tons of fun...
