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, i...

It is interesting / depressing (but kind of understandable) how anything that happens in a Boeing plane these days become newsworthy. At the same time, it is not surprising since the media is so crazy to make aviation catastrophe news where there are none. Like: A mother of two from Indiana , Stefan...

There was a classic runaway train Swiss cheese automation fueled derailment in CA. First, the dispatcher didn’t know what he was doing, fudged on car weights and maybe even sent the train without enough locomotives. The train had front and rear locomotives- not_electronically linked, but crews and ...

Here you have the new NASA / Boeing MD-C-152-737.

From YouTubez and rail perving, it’s been my observation that dynamic brakes aren’t half bad at slowing a train. Conversely it’s one unit working to stop 30 to 40 cars or more so it can’t be THAT effective…you got 6 axles of braking vs 160 axles of momentum. 16:1, roughly. What on Earth are you tal...

I spotted a guy wearing a " Boeing 737 MAX " shirt. Similar to this one , same color, but without the "-8", the text above the Relicliner and "Boeing" was preceded by its logo . I can only ASSume he was Verbie . Surprisingly the shirt appeared to be intact , but loose ...

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.

Yeah, it's called conservation of momentum.

Evan (yeah you are being somewhat bold). The grain train lost 28 mph in 38 seconds of emergency bake application. The crude oil train lost 1 MPH in 8 seconds of emergency brake application. THIS is bold. Brakemen used to run down gang planks turning brake wheels one car at a time. The Westinghouse ...

In any case, having a gazillion ton vehicle with a gazillion wheels and a gazillion brakes and have it slow down at 0.5 MPH per second at best is either stupid, or bad engineering, or there is something wrong with the condition of the brakes and people don't care. It is so ridiculous that it defeats...

I watched the video and was like yeah, kind of interesting.

Now the comments. LOLOLOLOLOLOL

So much creativity wasted

2) The significant weight of the train (about 286,000 lbs or 130,00 kg per car) represents a lot of momentum. It is also a lot of normal force, so the braking acceleration should not be affected... unless the weak link is not the friction between the wheels and the rails but between wheels and the ...

The Boeing Leadership was originally McDonnell's, and became a merger prize when M-D bought Boeing with Boeing's money in the late 90's and kept the Boeing name as a disguise .

Fixed?

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 whee...

The following video shows a derailment of one train while another is passing to give you an idea of how these types of circumstances unfold. A grain train was traveling west on double track when one of its car's axles failed causing it to derail onto the adjacent track moments before an eastward oi...

That plot is a lot more readable! Too bad it's missing the normal acceleration trace though, that one matters. It’s not missing. It’s right there in the blue section. I re-traced the plots and re-shuffled (including bringing up the wind plots that were in the next page) to have a longitudinal secti...
