*** Youtube/Video thread ***

The Tim Traveller is, unsurprisingly, a person called Tim who travels to interesting places and makes videos of them. They have some pre-pandemic footage they're using at the moment. They're particularly interested in mountains and railways, so they weren't going to pass up the chance to make a video about this combination of the two, finishing with an underground railway station which is over 3500 metres above sea level. I wouldn't have thought there was such a thing, but they managed it by building it inside a mountain. Over 100 years ago. Impressive. Almost as impressive as the price of a ticket, which is priced at "Wahey! Tourists ahoy!" levels. Although to be fair maintainence costs must be very high.

That reminds me, I've been meaning to see if there is such a thing as virtual train journeys (I don't mean VR I mean actual filmed footage from the train in real-time).

I'd love to ride some of the world's great trains/lines, but travel is currently not possible (with or without Covid) so perhaps a film of the route would be the next best thing..

Tim's channel is awesome, been subscribed for a long time.
 
I'm watching this at the moment - a moderately detailed overview of the engineering involved in the SR-71 Blackbird. I think there's a lot of interesting stuff on the Real Engineering channel. Roughly, it's engineering explained for non-engineers.


Some stuff I didn't know and found interesting. For example, I didn't know that when fully loaded the SR-71 was mostly fuel. Literally so - 59% of the weight was fuel. It was first and foremost a propulsion system. Also some interesting details about how the engines changed on the fly to make such a wide range of speed possible with only one set of engines. I also didn't know that the engines could have produced enough thrust to make it fly even faster. Quite a lot faster. The limit on the top speed wasn't the power output of the engines.
It was the temperature caused by air friction
