Why do circuit breakers go up for on and down for off?

Stick train wheels on your car, run it on rails, learn the difference. Rolling resistance is what you need to note here.

BTW, we in the land down under are one step ahead of you. Where we need to run a road vehicle on rails, boy, do we have it covered!

Nah, there'd be the smell of woodsmoke and the fire brigade would be called.

Ever heard of *friction*? Possibly a new concept for you?

You think a lot of things, most of them quite fanciful.

Stairs? There's no stairs! Those pesky passengers on top have to climb up to their seats. That's why there's always a big rush at the doors - first in, best dressed on the lower seats.

Not for me.

I got a completely different result with a day surgery.

I didnt bother with a mask because none of the reception staff did, even tho all of those in the waiting room did with the initial consult. No one said anything to me and didnt with the actual day surgery either.

Didnt happen to me.

I dont bother because no one seems to care.

Take it up with

On some lines, you don't want the really big engine, you want the really slow engine :-)

Yeah, tell that moron who turned his car into a tin can because he cut off a fully loaded tractor-trailer (80,000 pounds) that "it stops in a safe distance". Even with NHSTA requiring e-stop in 250 feet ... well, that's 250 feet after the e-stop is hit. General recommendations for safety are to give trucks AT LEAST 500' stopping distance.

Good thing that train is confined to that 56.5" little "rail way" thing then innit? Really easy to not get clobbered by one -- just stay off the tracks!

As an aside, 30 cars is pretty short. Probably a local run for businesses directly served by the railroad. Your standard inter-city run is going to be more like 90-100 cars (possibly a bit longer), and weighing in somewhere around 350-400 times a tractor-trailer.

I dunno about you, but I'm certainly happy to "only" see two of those a day (plus probably 2 more at night, but never went to check them out), instead of the 1400-1600 trucks that'd otherwise be required.

Interesting, snopes has a similar dismissive article for the one-finger salute.

Fark. Hard to see how they got the rails like that.

If you do that, then those wheels will be very low friction and braking will be as bad as with steel wheels.

You need something that is soft to increase the contact surface and grip. You have to choose, one thing or the other. Can't have both.

Well you could have a train having steel wheels, but with rubber tyred wheels that could be dropped onto the track during heavy acceleration, heavy braking and for steep hills. But generally, steel wheels work well enough.

If you had tyres, you could get rid of the rails. Do you think it'll catch on?

Doesn't the Paris Metro have tyred plate-ways?

Yes - at least one line did in the 70s.

"Manners" in this context is just a way to bully people. Some "manners" may be devised just for this purpose.

There are things making a fuss about, and there are face masks. I am not convinced they have or had any efficacy whatsoever.

But I carried a few around to slap on for appearances sake

Google says it is the Radisson Metro Station in Montréal, Canada.

Looking at the photos, you can see the rails are special.

I have not found photos of the car wheels. Ah, here:

If they need extra traction they drop sand on the tracks.
