IMG_4704IMG_4705IMG_4706Figured some of you might enjoy coming on this journey with me…

I was at the club Friday night and a fellow member was selling some stuff. He had a Williams (pre-B) U33C I was interested in… we were discussing price and I was looking the engine over when I discovered that the front truck appeared to have a stripped gear. A quick truck removal exposed an apple-cored main drive gear. We came to an agreement that he would include an early Williams Train Master “for parts”.

So I now have two “new” engines! Of course the trucks from the TM won’t fit the U33C… I’m thinking that the truck from the Bmann parts site should work for the U boat, so that’s not a big deal. It runs great otherwise…

So then I have the Train Master. That one has issues. It’s missing all of its handrails, and it has some scratches on the roof. It also seems to have a bad motor… I didn’t really test it until Saturday morning, when I did I found that it was very lumpy/jumpy at low speeds and only went forward. I read somewhere that the very early Williams stuff didn’t have e-units so I figured that was the case with this one (it’s not).

I opened it up and found an (obviously original) e-unit dated 9/84 with 4 melted transistors and its wires cut off and a bridge rectifier wired in its place. So there’s my forward-only, and a clue…

If I remove one motor from its truck it runs smooth. With the other motor removed it runs a little lumpy, and with both motors in it runs very lumpy (like two locos with very different gear ratios fighting each other). The bridge rectifier gets pretty warm with just the bad motor, gets hot with both motors, and stays cool with just the “good” motor. Both trucks roll smoothly with motors out, and both motor shafts are not bent. So it appears that the one motor can’t run smoothly/pulls a lot of juice under a load.

I’m not sure how far I want to go with the TM, it’s a cool engine but it has a very cheap plastic feel to it and it doesn’t really impress me much. I currently have the “bad” motor out of it so it’s one-truck drive, and I’m thinking about trying to replace the transistors on the e-unit and running it as a single-motor locomotive… like I said, I’m not too excited about it. I’m guessing I won’t be able to find motors that will drop in, so re-motoring will probably require replacing both trucks and motor mounts and motors. $$. Meh…

Jon I've made other posts that sometimes a radical motor-ectomy is required to achieve the smoothest operation.  The notable exceptions are Lionels with back-drivable gears, where the motors can actually help each other.

My experience with Williams diesels is that they are powerful pullers.  As long as the @#$%^& rubber tires are present and in good shape, either of those locos should pull a respectable train with just one functioning motor.  If you're determined to restore them to dual-motor operation, wiring the motors in series instead of parallel will get you better slow-speed control and a wider usable throttle range, at the expense of top speed.

To the best of my knowledge, both of these units use the same truck block. You should be able to swap them between each unit with out any issues. It is the #322 truck. I am fairly certain Williams/Bachmann only used three different truck casting for all of their locos. That makes it easier to find parts and repair them.

The trucks, reverse boards and motors are available on the Bachmann web-site. Note that the truck is listed at $43 under the Universal and Trainmaster categories for the one with the coupler and $33 for the one without the coupler. They only list the one without the coupler for the U33 in the U33 category. You will have to look under the Universal or Trainmaster listings if you want one with the coupler, which I recommend since you get a complete coupler assy for only $10 more as opposed to $15 for the coupler by itself.

The older, non-flywheel motors are not as efficient as the newer flywheel equipped motors and will draw more current. If you replace one of them with a newer flywheel equipped motor you should replace both.

Having just experienced lumpy performance with a dual motored rdc, the problem turned out to be a bad gear.  That brass gear eventually split and seized the motor.  My solution was to swap out a truck from a dummy unit and run it with a single motor.  I just recently replaced the bad power truck with a replacement from williams. 

I definitely appreciate the replies. Thank you all!

I think the Train Master will probably stay single motored for a while, maybe indefinitely. I am going to try throwing some transistors in the e-unit so that it has reverse, and I will at some point try to find a set of hand rails for it. Quick question, are these close enough to the Lionel TMs that their handrails will fit? That would broaden my search if they’d fit…

As for the U boat… it’s quite a bit heavier than the TM, and it will make me feel all warm and fuzzy inside if it had both motors working, especially since they’re the smaller motors… so I’m going to get a new truck for it…

Update: I messed around with the “bad” motor from the Train Master and confirmed that it’s bad. It’s lumpy (hits a slow spot once every revolution) by itself/no load running on an MRC dc transformer. I think it has a shorted winding. The commutator is clean and there’s no carbon in the gaps…

I went down to the electronics store (yes there’s actually an old school electronics store still open!!) and picked up $10 worth of transistors and after some very careful and tedious soldering I have a working e-unit!

I should be able to order the truck for the U boat on Friday…

So I might have made this confusing by talking about 2 different engines in the same thread… (they were bought as a pair, I wanted the U boat and the seller threw in the Train Master for free).

The U boat has a stripped main drive gear on the front truck. Otherwise it’s fine. I’m going to replace the truck and then probably repaint it to Conrail…

The Train Master has a bad motor and had a bad e-unit (fixed the e-unit). I’m not as excited about this engine, so I’ll probably just run it as a single motor unit for the foreseeable future…

Here you go:

This is what I used for paint.

Since the frame is metal I used some gel-type paint stripper, sandpaper and elbow grease to remove the paint. I then used a bunch of light coats of the blue, added the white handrails with some testors paint and a small brush, and sealed it with the satin clear.

As for the shell, I took a gamble and just wet-sanded the lettering and numbers off and sprayed the blue right over the factory finish. I figured worst-case if it reacted I would just strip it all off. It turned out perfect.

The decals were straight forward. Dip in water, slide into place, let dry, add setting solution…

I ran into some trouble with the clear. I probably should have left that step for when I was a little less tired… I think I put it on just a little too heavy and it wrinkled in a few spots. It’s not horrible, and you don’t even notice it when it’s in motion… I do have enough decals and paint to do it over, but I might decide that it’s good enough and just leave it as-is… pretty frustrating to get that far with no issues and see it wrinkle after the last step…

So I’m calling the U Boat done! I ran it at the club Friday night, and Saturday afternoon at the open house for several hours with no issues. I am pretty well convinced that I can live with the slight defects in the clear coat, I don’t really notice them when the engine is running around the layout…

I guess that means I have to give the Train Master some attention. I’ve got the shell soaking in isopropyl alcohol to strip the paint. I’m not a fan of the Southern Pacific (except, of course, the daylight scheme, which is one of the most beautiful paint schemes in all of railroading) so it’s gotta change its clothes if it’s going to stick around…

I think I’m going to try to make my own handrails because I think I would enjoy the process, and I might look into a pair of new motors eventually.

I’m open to suggestions on the paint scheme with the following thoughts: must be “different” (not Lackawanna or Virginian), must be simple (I don’t want to mess with complicated masking and paint bleed issues), does not have to be prototypically accurate but should be at least relatively plausible, readily available decals would be nice… I have a few ideas but I’d like to see what others come up with, might be something cool out there that I haven’t thought of…

Thanks again to everyone that has contributed to this thread/project!!!

Since your U-boat is Conrail, why not paint the TrainMaster for the Reading?  Dark green similar to Pennsy's, and gold lettering.  Lionel decorated one this way in the late '80s or early '90s, if you need a visual.  The best part, they were used in passenger or freight.  Great effort on your part, thanks for sharing!
