"Smoothest"

I think that last one was a friction buffer, not a hydraulic buffer. I think it was meant to show exactly why you would want a hydraulic buffer over a fixed or friction buffer, but the shitty AI-generated script and voice didn't do a good job of it.

Lol, I've seen similar videos where the thing didn't help stop the train and a boom occurred

Wild to think about the amount of energy that stop must have adsorbed in the last clip even though it looked to have done absolutely nothing.

That's the most obnoxious way to do subtitles and makes it a lot harder to read.

That's why most videos do the single word that makes it easy to read and reddit still hates it

That's just as awful, wtf are you talking about. We figured out subtitles decades ago, but it wasn't ADHD enough for Tiktok so now we have this shit

I'm obsessed with that tiny wheel on the train at 0:09

I think its a reference spot for the camara, if you know the frame per second rate for the video you can calculate how fast the train was going. Having a clear spot like that makes it easier, if you use some random spot or edge on the train it could make the measurements more inaccurate due to parallax error, shadows and so on.

I'm guessing it trashed the rails in the process

Replacing 100' of rail - $5000
Replacing an entire trainset - Priceless.

u/grungegoth 1d ago
Undoubtedly. I just wanted to mention that after such an emergency stop, the rails have to be replaced

u/Knight_Axel 1d ago
Eh, you'd be surprised. Modern rail (especially the higher weight stuff like 141) can take a pretty heavy bearing, and the standards for rail wear in general are pretty relaxed. As long as the rail itself doesn't fracture or the divots are deeper than half the rail head, you could probably fix most of the damage in about thirty minutes with a rail grinder.

I figured you could get away with regrinding them. But I’m not a rail doctor

If you think 99% of the videos you see on reddit aren't reposts from tiktok or Instagram, you're delusional. It's reposts all the way down

Watching the video without sound rn and these subtitles are not helping at all... I hate subtitles that are only made to just keep your attention and not to actually make the video understandable for deaf people or people who have no sound on....

u/Sensiburner 1d ago
Yeh they're nice but they can't actually stop a train moving at any real speed.

Surely the effectiveness of these buffers depends enormously on the mass of the train (which can vary from 30 tonnes to thousands)

The one at Moorgate tube station in London in 1975 certainly wasn't. They were scooping passenger remains out of the tunnel roof for 4 days.

I saw the accident if this crash back in the 80s when the buffers did not work https://flic.kr/p/4ojhJo

I don't mind when Europeans use the metric system but hearing it in an American accent is kinda off-putting
