I just installed a Williams True Blast 2 sound unit in my Williams 44 tonner, and I was very disappointed in the tinny sound of the prime mover. It might be that the 44 tonners really sounded like that, but I don't know for sure.. I'm considering getting either the GP30 or the GP38 sound units, and I was wondering if the sound quality of these units is any better.

That's a big difference from the $219.95 list price in the Bachmann catalog! I'll look into it. Maybe they have a reverse board as well. Bachmann is sold out of them.

Wow! Thanks! That's a good deal!

Yes indeed my EP-5 and my FP 45 both have flywheel motors. My only concern is the sound system. They both have a full sound system with locomotive sounds, etc. But there's little else in the dummy unit, so there's probably enough room for everything. Thanks for the heads up!

Thanks, Len!

I have a Williams MW EP-5 and a CP FP45 that I bought about 20 years ago, They both came with a dummy unit that had a sound board. I thought it would be neat if I powered them up with the Williams power upgrade kit, and it looks like it's easy to install. I'm looking at the image in the catalog, and it looks like the kit comes with only one power unit. Is that correct? That's not much power for an engine that size. Has anyone out there have any experience doing this conversion?

Thanks, 671! I'll look into that unit at train world. That's $20 less than list price, which would pay for shipping.
I noticed on the Bachmann Williams parts page (I felt like a kid in a candy store there) they also a reversing unit for older Williams locomotives at a lower price.
I have no idea what the difference is between wiring the motors in series rather than parallel, but I'll look into it.

Thanks again!

I have a Williams GG1 that I bought way back in 1981. They didn't have electronic reverse units way back then, so I had an E-unit hooked up, connected to a bridge rectifier. I'd like to buy a Williams reverse board with lockout (item 00249) for this engine. Will this reverse board work on a Williams engine this old? Will I still need a bridge rectifier?
