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.

Well, for anyone who's ever (almost) had their Harley get the better of 'em, this thing is the hallmark of stability.

Hi Herb
that double-decker tramcar would probably weigh in at about 10 tons empty and probably less than 15 tons with every seat full and crammed to capacity with standing adults- Remember then you used to get more adults/ton than you do these days :P

All braking would have been done by the tram motor (dummy), with probably only a lever parking brake on the double-decker trailer car.

So who needs full-sized knuckle couplers for such a "tiny" load - A flat drawbar and some decent pins and some safety chains as backup will do the job ;)
