And continuing the theme, our local transit authority has this: https://www.youtube.com/watch?v=DL6jKOCeVec

I've actually seen it (sitting, not in operation) a few times, though not recently.

Or how about... real afterburners? https://en.wikipedia.org/wiki/M-497_Black_Beetle

Oops!

I guess my point is that if it’s soooooooo important to electrify transportation, why is there sooooo little talk and effort on US freight rail? Here are my guesses, in no particular order: 1) No money. 2) Long distances to be covered, which often are distantly distant from sources of electric_powe...

What was the pilot thinking?

Words to the effect of "Hold my beer"?

Couple of things to mention. - To start to move form zero you have a quite a bit of static friction to overcome. It takes much more power / force to just barely start moving than it takes to keep moving and even accelerating at slow speed (as can be seen in these videos). - For traction you only ha...

The clincher for me is that I see almost no effort going into electric trains, which IMHAHOO is the PERFECT place. Half the wiring is in place, electric-motor locomotives are also SORT OF in place… AND WHEN IT COMES TIME FOR BRAKING, the dynamic brakes dump the electricity BACK INTO THE SUPPLY GRID...

Kidding aside, I remember in flight training more than once my instructor basically saying not to freak out if a door pops open... "An open door is not an emergency". Well, if you open it and tie it to the strut maybe...

That stuff always amazes me as my household power tools do not like being stationary with lots of electricity running through them…the magic smoke starts to leak out fairly quickly. Keep that in mind next time you hear an EV fanboi going on about how "DC motors have infinite torque at 0 RPM&qu...

Flange greasers??? https://media.tenor.com/nYk9NUeTXtUAAAAM/oh-my-george-takei.gif \ Okay yes I can understand the need for same, especially as a resident of an area with a subway system that has a lot of sharp curves. But if the grease migrates from the flange to the horizontal wheel surface... bad...

I wonder if this guy also has a solution for the shippie vs. bridgie issue.

Airbags for bridges?

I'd seen photos of that phenomenon before, but never a video.

I think a big part of the issue is economic, and that's a tough problem to solve. It doesn't appear that railroads (in general, in the USA) are exactly making money hand over fist, and requiring equipment and maintenance and procedures at the same level as airlines would make those profit numbers ne...

Seems like we need to apply more pier pressure on our elected officials.

Fotografia numero quatro: Indeed!. I see flyboy, Dummy and Bobbie.

My biggest takeaway from that one is they need to train some air traffic controllers, and fast!

Wow, talk about a not_stabilized approach!

Quote=Gabriel Train brakes suck. I blame: 1. Engineers 2. Economics 3. Greedy, profit-driven, Boeing executives 4. The squid 5. Donkeys (the original railroad locomotives) And horses! https://scontent-bos5-1.xx.fbcdn.net/v/t1.6435-9/118472415_10158962975278243_1328085136840817502_n.jpg?stp=dst-jpg_...

How come a sedan, a 18 fully loaded wheeler and a 747 can stop in about the same distance from say 50MPH?

Because they're not boats?

Yeah, Tampa in the 80's, just googled it.

Well I was figuring you could fit about 4 Corgis in a square meter. In practice, it depends on whether they are lying, sitting, standing, or running around.

Time for Captain Trimmer to write another book: "How to avoid hitting bridges with your huge ship"

Oops just realized we already have a thread about this.

I'm going to go out on a limb and suggest that procedures were not_followed.
