ROFL, there\'s still people wearing masks here. I went to hospital
with a suspected broken thumb and everyone had a mask on. They glared
at me sternly when I refused.
It is mandatory here in hospitals.

Pretty much the same here.

Not for me.

I was discharged from hospital 2 days ago, my 4th visit in the past 2
years and I, as a patient, was also required to wear a mask as were
*all* staff and visitors.

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.

> If you refuse, you get offered the door.

Didnt happen to me.

And it is to protect other patients from YOU.

Most assuredly. I wear the mask out of consideration for others.

I dont bother because no one seems to care.

Should be used on all tracks, then perhaps trains could stop in the

Do the math.

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

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.

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

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.


> cannot, it\'s not fit for purpose. If something unexpected happens, it

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.

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.

All that need is train wheels made of rubber as hard as steel.

(Something to with the friction between similar metals I think.)

There\'s fuck all friction, which is why they want the cars to wait
for the train at a level crossing, and not the other way round.  And
why the new tunnel the Germans are building couldn\'t go right
underground and had to be installed on the bottom of the ocean,
because the pathetic toy trains couldn\'t handle the incline.  This is
the 21st century, we have cars.  Public transport is for chavs.

If there were no friction between train wheels and track acceleration
and braking wouldn\'t happen.

The small contact area and the great mass of a train is what does the
trick.

The reason railway tracks are so level is so that the engines can have
the minimum power to pull the train. Very steep inclines would require
extra locomotives to be put on to get up the hills.

Which they add to get the trains over mountain passes.

If you do that, then those wheels will be very low friction and braking

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

heavy braking and for steep hills. But generally, steel wheels work well
enough.

The f\'ing steel wheels wear very significantly.
