Having had, at one time in my very UN-illustrious motorcycling days a woods bike with a Villiers 8E engine, I can only say how did such an underpowered POS drag a railcar around--and how long did it last screaming along wide open all the time?

Another POS manky-motor for Hot Rod Herbies unique analysis !

- - - - - - -

The McKeen motor car’s 6-cylinder overhead-valve gasoline engine was a source of constant irritation to the V&T’s motormen and mechanics.
It was hard to start and so rough-running that it required a massive flywheel at the end of the crankshaft to keep it from stalling.
In order to reverse the direction the car moved in the engine first had to be shut down, after which the tall lever protruding from the upper center of the engine — connected to two sliding camshafts on either side of the engine, each with two sets of cams — had to be moved.
This changed the valve timing, so that when restarted the engine would then rotate in the opposite direction.

- - - - - - -

Herb, sounds like a 'ton-up' wasn't possible in a McKeen either.

For RC users, you could probably use an airplane controller, for prototype operation.
Just STOP, shut everything down & change all the wiring around before reversing !!

:f:

Wonder how they got propulsion power to the track with the car in post #18? Couldn't rely on the rubber tires rubbing on the rail, so were the tiny wheels just for guidance, and the road wheels ran on the ties? Not a rough ride if you get going fast enough on a motorcycle, I know from experience, but LOOK OUT for the switches!!

Hi Herb,
Not sure - I didn't get a chance to get a photo of the back of it but I suspect a shaft rubbing on the back set of road wheels transferring power to the back set of wheels either directly or through some type of a mechanical gearbox/transfer case or by hydraulics but only when the rail wheels are hydraulically lowered and locked. When the rail wheels are up this shaft is moved clear of the rubber road wheels and no power is able to transferred to the rail wheels in the "up" position.

Si

BTW There is a bit on the McKeen engine somewhere in the dark dank basement of FreeRails, but possibly not any more onfo than what you have already provided, Si. The flywheel on the McKeen isn't overlarge--The flywheel on the Brill engine of the EBT's M1 (ca 1910-1920 design) is more massive, and also had the generator armature for more WRsq. That engine is smaller--1980/CID. Did a lot of work on it in years gone by.

One of the many McKeen faults was that in had the patented (I think) McKeen ''Octroon" clutch-- which had very limited amount of ''slippage'', making a smooth start a real challenge.

Hi Hot Rod Herbie :)

I have been looking into motors & drive-train bits of late.
Possibly for a totally INSANE :Crazy: railbus/truck or crispy critter experiment !

Thanks for the tip-off on the McKeen patent.
Sound like it would be useful ripped up in the outhouse !

:f:

I did for a few milliseconds consider getting into building gyroscopic-monorails. :shocked:

But in the end common sense prevailed...
...& a cheap Chinese motor in an ol' clapped out kit, seemed a safer bet !!

:moose:

Si.

OK, here's another bit of craziness/oddness/etc...

This job flew off the "high line" after just a few trips and lost several vital pieces in the tall grass at the bottom of the "canyon".

Easy come, easy...aww, forget it.
