Re: Railroad Thread

There also could be an "optics" issue with that. "The train operator saw the bus full of nuns over a mile away, but didn't hit the brakes until the last second." would cause quite the media frenzy. Unrelated but possibly interesting: I wonder if I went out on the highway, got my ...

Re: Math….

Ass-uming constant deceleration, what is the deceleration rate of a train that takes a mile to go 60 to zero. Don’t tell me, I’m going to get a pen and paper, and do some ciphering. I'll take a crack at doing this in my head... 0.5 MPH/second? I'm thinking if a train decelerates linearly (an ASSump...

Re: Railroad Thread

I... don't recall there ever being an inspection! Though I only worked there for about a year and a half. The unit wasn't in any packaging... but I think it was in the bottom of a file cabinet covered in dust. I will say I've owned cars in this state for over 40 years and never had that test perform...

Something I thought of re braking... take a look at this (what I think is typical for the USA) attachment of a railroad rail to a tie: https://upload.wikimedia.org/wikipedia/commons/0/07/Dogspike-on-wooden.jpg The rail is restrained vertically by lying on the tie (downward) and the spike (upward, in...

Re: Railroad Thread

To be fair, a lot of people have experimented with alternate means of stopping trains, like putting buses or tractor-trailers in front of them, and it never seems to work very well. :roll:

Re: "This is your captain. Brace for impact"

It's a bunch of people who have convinced themselves that all politicians are s**theads, and somehow think that electing the worst s**thead they can find to office will somehow improve things.

Hard to say who would want to buy it. It isn't really near anything, other than a muddy bend in the Missouri River.
In fairness, isn't that true of all of St Louis?
They do have this cool arch that according to at least one person, could be used as a runway if laid on its side.

Re: Railroad Thread

Not a train expert, but I read that trains have brakes on all wheels which are spring loaded in the "max braking" position and the spring is resisted by air pressure. So for normal braking you release part of the pressure and then re-pressurize the lines to release the brakes (there are b...

I saw something last night that reminded me that, in spite of lousy customer service, relentless pushing, not_doors sometimes falling off aeroplanies, and squid-related conspiracies, flying can sometimes be enjoyable.

Re: Railroad Thread

Good point! According to the intarwebz, COF is around 0.5 for a dry rail, 0.3 for wet, and a bit less if frost is present. I know leaves can also have an effect but couldn't find a number for that condition, probably because it's so variable. Dumb question but, do trains have brakes on all the wheel...
