Yes, I am running two powered F-7’s on the same train, one in forward and one in reverse. I took out the circuit boards on my F-7’s and installed bridge rectifiers(need something in there, a bridge rectifier or diode bridge, because Williams uses D.C. can motors), so they can start in the same position every time. Their pulling power is additive but not double a single engine because of friction. For my Williams train I am using a 275 watt post war transformer.
Brad : I agree. Just bought Williams Locomotives. I enjoy them more than my new Lionel Canadian Maple Leaf set. The Lionel lasted 2 weeks before the sound effects took a dump. Nothing but Williams for me now!
Thanks for letting me post. My new MRC 270 watt transformer will arrive today. Can’t wait to hook it up! I will be using it with my Williams and Lionel. Can I expect any glitchs ? Later COOL WALDO
I couldn’t agree with you more Williams/Williams by Bachmann are absolutely the best conventional trains there are. Indeed they are like patato chips and pistachio nuts you can’t just have one and especially when it cokes to cost, you can get two AA sets for the price of one set of Railkings that could stop running at the drop of a hat. I am addicted to their F-3’s, F-7’s, and the rest aren’t too shabby either. The only drawback is they won’t sell you parts when you need them.
I’d like to defer, the MTH Horn and bell conventional diesel engines have 2 RS385 flywheel can motors and weigh around the same as a conventional Williams, and Lionel’s Conventional Classics engines have more weight and power but not as smooth because of there original motors.
I have three Williams(before Bachmann) SD-45 diesels and run the three with one handle on my pw ZW, only drawback is that I have make sure I limit the number of freight cars(30 to 33 cars) on the train or it derails on the curves. Bought another set of Williams F-7 ABA units, they run good with the new motors by Bachmann installed, as I used their original motors for my other F-7’s(the Santa Fe set). The only complaint about Williams is the variety of their cabooses, only the N5C, regardless of what railroad.
I once pulled 9 passenger and 22 freight cars all at once… with only 1 Lionel engine… it was a GP7 with front truck drive ONLY… it had a vertical worm drive pullmor motor with 2 axle magne traction and 2 tires. ONLY 1 motor and it pulled 31 cars including passenger and postwar cars… I was impressed, I’m sure a quality 2 can motor Williams Diesel engine could pull that, but a 1can motor Williams, not a chance. I’m pretty sure Williams makes all there diesels with 2 motors, but a 1 motor Lionel Geep pulled a line of cars that was to heavy for a 2 motor K-line switcher to pull and those things are powerful. I pulled it on 0-60 curves, so there was no stringlining problem, I have an MTH engine that could out pull any Williams diesel ever made, the Premier SD90MAC, I know it can pull well over 100 cars on 0-72 curves. 2 RS-385 brass flywheel motors with 12 wheel drive and 4 tires… the engine weighs over 8lbs and is 20.5 inches long. it cost much more though than a williams. I know Williams have some really good pulling conventional engines for a low price, that’s the good thing about them but I’m a MTH/Lionel guy, so I don’t purchase there products.
