Madison, I have the following NWSL parts new (never run but test fitted): #250-6, 25 to 1 Idler Gearbox, 3/16" axle #251-6, 25 to 1 Gearbox, 3/16" axle plus a few odd parts from a #495-6 universal coupler set You can have it all for $10 plus $3.00 postage. I'll be going into the hospital Monday 8/26 for a few days, and won't be able to respond after 12 P.M., but its not going anywhere. Let me know one way or the other. jackson

I would like to know, out of curiosity, what an idler gearbox means. And I like the Idea, although I will have to make it a 90 degrees to the truck, but otherwise, that is what I had as an idea from the beginning. Thanks.

For the car that this is going into, I certainly can, and it's a pretty common practice for trolley freight motors where the motor won't be seen and it also lets you put a decent sized motor and flywheel in...

With the Bowser street car truck, and a whole lot of diesel trucks, street car trucks, etc., available, I would think, in a DIY project, that powering the rear truck/finding a power truck, if you have the front one free-rolling, is gonna be a whole lot easier than powering the unusual front one, compounded by the constraint of a sharp radius.

I don't always want to run a second car behind, and the only trailer I would use for that, is a trailer that I already bought the trucks for. I was looking at a k-line locomotive I have, and I noticed the worm gear has the same gear spacing as Lionel, so I think I will purchase a k-line replacement worm gear, and mount the motor vertically. I would have enough room for the motor inside the hole in the floor. I would have to then make an arm attachment from the top of the truck around the...

Yes, three immediately come to mind: 1) The tolerances between a vertical pinion gear and a horizontal ring gear are quite critical; do you have the tools to properly align these and are you familiar with the use of Prussian Blue and lapping compound? 2) The vertical play becomes more important with a leading truck opposed to a trailing one in the prevention of derailments, are you planning on building in a means of adjustment to get the amount of play exact? 3) The entire motor/drive/truck...

I do have the tools that can allow me to create a strong metal arm to hold, and adjust the position of the motor. This arm is only attached to the truck, and will move freely up to down and side to side. I don't want to compromise the back truck because the motor in the front allows for a partly lit interior, and the fan and smoke unit could be moved to the baggage section. I pushed the motor car around curves and on a 036 curve, it works fine. I will have to add a little weigh for added...

Madison, did you follow mwbs suggestion of looking up nwsl.com under drive units/carpet drive yet?..the flees aren't ready for release and haven't been for a while{darn it}. You will note that the carpet drive is really 2 rail friendly, but that hardly limits it to 3 rail useage by using another truck as pick up leads for powering it. You could get lucky and mesh the gears correctly as you last mentioned, but you could easily not get it right and toss you time and investments away in a few...

I have bought Lionel trains from the EBay guy before, but I don't want to have to cut a truck in half, rather then just buy a gear box, like Burlington Route added a link to. I think however, I would not have enough room for the gearbox the B.R. told me about, because it would have to turn it 90 degrees. I think that that would be my best bet, but a little modifications.

Well, to answer B.R.'s question, the spacing is to scale, and the axles, center to center is right at 1 3/4", and the front on is 2 and 11/16". The smaller wheels are 33" in real life, and the larger front wheel is 42". The only way I could use a powered truck for the back would mean I would have to cut a hole in the back or I find a motor truck that is skinny enough to fit the motor and the gearbox. I would have to have the truck about and inch or less in height, no more. And one more...

Madison, you can raise the truck bolster higher in the frame to account for any given drive truck you might find if that's an issue for use of it. Width of any power truck is something to consider too. That auction you were shown- the power truck in question is the same as the one I have here; axle spacing at 2 1/4"...close! The motor though sits out nearly a 1/4" from the outside of the wheel due to the nature of its design. I'd truely suggest the gear drives I showed you...I doubt highly...

You'd need a drum nearly as large as the large drive wheel and a front to back running shaft to drive it off of- a slightly...

Getting/fabicating the correct front truck has to be one of the peaks to be surmounted with these cars..great that you have done that. Maybe a Marx mechanism that, as in their cabbed diesels, turns with the front truck is workable, after engineering a gearing to drive the front axle. Or possibly powering the rear truck, where complete mechanisms, with truck frames that can be modified, can be used.

Re: Powering a McKeen Car

I meant to add...since you have the difficult to form body and unusual front truck fabricated, you are over the big humps. I hope others on here with more experience powering creations, can offer mechanical suggestions. An old choice for rear truck power was that chain driven truck offered by Walthers for their gas electric kits. There must be something more modern than that, and applicable to three rail, out there.

I had an idea by the cylinder drive. I would have a small pipe that is above the front axle, and would be powered by a motor width wise in the engine. By doing that, the rubber band would always say vertical. Although it would take some time to build, I think that is the best bet. I have pulled apart both a VCR and a R.C.

Very nice job. If it were me i'd let the front truck be the dummy and consider powering the rear one which from the photos i've seen appears to be of a more traditional configuration with equal diameter wheels. Depending on the wheelbase needed i'd consider the power trucks used by Lionel on their RS-3's or the ones used by KLine on their S-2's. If either of those were of the correct wheelbase you could simply grind or sand the side existing plastic side frames flat, and then using scraps of...

Because the real McKeen Cars almost never hauled more than one trailer, ever. So I don't need any more then the power to get it up a fair grade. Also, it would be a lot harder to power the back truck rather then the front. I have a exhaust pipe which was such a tight fit in between the wheels, that to make the 036 curve, I had to pinch the pipe in able to make the turn. I don't think I can power the back wheels.

Re: Powering a McKeen Car

In the photos i've seen the only part of the exhaust pipe that's visible is from the rear. Sometimes in modeling we have to make compromises and eliminating an almost never seen piece of underbody detail in favor of a simplified reliable power unit is common sense to me. Those HO power units will NOT work. If i can find the one with NWSL gears, etc. in my junk box i''l sell it to you for $10 so you can see for yourself! jackson
