Williams Electric Trains

Thank you, Wayne. I'm surprised that only one axle per truck is powered. It's hard to see, but it looks like there should be room for another worm and gear set, on the motor's other end.

The pickup roller takes up the space where a gear would go and the roller can't go between the axles because the motor is there.

Thanks. Drive has similarities to a Q-car drive for trolleys. Adapting these drives might be possible for other uses.

I was thinking the same thing Its nearly impossible to buy any parts from Bachmann If you look at their parts order system most engines only have 8 parts available One of them is the powered chassis that sells for more than the engine sells for and none are available Simple things like truck side frames arent available now for nearly two years The 70 tonner isnt even listed for parts sales

Unfortunate. I could use a body and maybe sideframe, but rest would be only useful for a different project. Have to put this down low on the "to do" list.

These are the two I had painted Reversed the leads on one to travel reverse to the other

Very nice, I love the 1988 paint scheme.

If you can get it in your railroad's livery I think the Williams by Bachmann paint jobs are pretty good.
The 50's happens to by my preferred SP era. The Tiger Stripe theme on SP switchers was used from 1947 to 1958.
Could it get any better? I'll find out when I test it (it hasn't been run yet.)



Maybe I should blow the packing material dust off of it.

What did you have in mind?

Body looked decent enough to bash into a traction switcher engine; converting the drive is probably more than I want to bother getting involved with, but I could be wrong.

[The WBB 70 tonner is] not a very good puller.

I wouldn't have expected this, from Bachmann. Crappy pull, from an engine with die-cast trucks and frame?

Maybe they can get Mr. Dyson to come up with a neodymium magnet based motor that could be truck mounted and still pull stumps. Main problem is the motor will probably cost more than an entire Vision Line train set.

Last I heard, the Chinese are developing their rare earth resources, and have the market effectively cornered. I don't know if anyone is even looking for them, in the U.S.

But, I don't think a super motor is necessary, in this case. The WBB 70 tonner appears to have a bad drive design.

They have for a long time and our mines have effectively been closed or inactive for years.

Maybe not if it gets used as a switcher and only pulls 3-4 cars max; folks might stop expecting every engine to pull 25-50 cars up a 3% grade.

That might be OK for a cheap, used, plastic-bodied, bakelite-motored Scout engine. Wayne laid out three hundred and fifty dollars for a brand-new locomotive. I think he has a right to expect better performance.

A transverse motor with spur gears to drive the wheels, aka like a real diesel electric. You could even have one motor driving both axles. Lionel tried/still uses this but the motor was/is pretty low end. Not much low end torque.

I prefer that sort of arrangement, because it's backdrivable. Of course, you can increase the torque, by changing the gear ratio. Such a switcher doesn't need to run 100 scale mph.

Since it's a hood diesel, you could mount a narrow can motor vertically, on the truck swivel axis. There are a lot of drive design options.

Isn't 3-4 cars for a 70 tonner about right?

Maybe double that, but it seems that expectations are overriding reality.
