Not a chance given how much heavier any train is, let alone freight trains.

[rbowman]

Do the math. A fully laden coal car weighs about 140 tons. I've never been
bored enough to count cars when I stopped at a crossing but there are a
lot of them. Let's say 30 for the sake of argument, 4200 tons plus the
weight of the engines. Let's say 4 at 200 tons each. So, roughly 5000 tons
traveling at 50 mph. That's quite a bit of kinetic energy to dump in 300'.
I can hear snapping axles and see flying wheels.

[Dean Hoffman]

[😎 Mighty Wannabe ✅]

The wheels and the rails are steel. A train can never have enough
friction to stop at a short distance. The brakes can lock all the wheels
but the train will still move forward due to inertia.

You don't have 4 for a 30 coal car train.

And you can't do 4 loco engines on a cogwheel train.

It would just rip the teeth off the cogwheet drive.

[Rod Speed]

The PHucker/Kinsey was talking about a COG WHEEL system.

[rbowman]

The reference was to the Mt. Washington Cog Railway. The wheels are for
guidance but the motive power is a rack and pinion.

https://en.wikipedia.org/wiki/Rack_railway

At least on Mt Washington it's only the engine and a small passenger car
operating at less than 10 mph. They're not feasible for general use.

If I did the maths I'd get a more complete answer.

But there are many wheels.

A fully laden truck/lorry/whatever you call them over there can't stop as quick as a car, but it can stop in a safe distance. A train cannot, it's not fit for purpose. If something unexpected happens, it just ploughs through it. Trains are outdated technology and it's high time we got rid of them. Maybe a maglev can stop quicker?

[Commander Kinsey]

Then the wheels should be rubber like every other vehicle. Try driving your car without tyres.

[Commander Kinsey]

Surely cogs can go over 10mph. Your car gearbox is full of them turning at very high speed.

[John Larkin]

Trains are about 5x as efficient as trucks for moving stuff.

Has maglev ever really worked? Most maglev systems came and went.

More to the point, railway tracks are normally fenced off and it is
illegal for the public to access them except at level crossings - which
have lights/barriers to exclude the public when a train is approaching
or require those crossing to check that it is safe to do so (visually
for pedestrians or by phoning the signal box for vehicles). Unlike
roads, no one without specific authorisation should be on the tracks at
all, so trains should not need to stop suddenly.

RPI had a mostly working model maglev train and were trying to build a
full scale demo with about a mile of track in Rensselaer, NY. That was c.
1968. I don't think they even got the demo working.

China and Japan at least have working systems but a cost/benefit analysis
has never been friendly to the technology.

But they do anyway. In India they do it even at railway stations
and live on the rail lines too.

But trivial to walk around the barriers

Have fun doing that here.

Our rural level crossings dont have barriers.

Depends which statistic you believe. And trains can only go where there are tracks, so much loading and unloading and messing about at both ends.

I thought all Japanese trains were maglev. You get a refund if you're more than 10 seconds late.

Until they cross a road, then for some reason cars have to stop for them.
