Keeping the world's longest railroad tunnel safe

The Gotthard Base Tunnel in Switzerland is 57km long: and I think its greatest piece of safety equipment is nowhere near the tunnel itself.

Update, August 2023: despite all these precautions, a freight train did derail in the tunnel, after passing all the safety checks. No injuries, no fire, but a lot of infrastructure damage, and one tube of the tunnel will be closed for months. The investigation board will try to work out what happened: news.sbb.ch/medien/artikel/124073/reparatur-von-gotthard-basistunnel-wird-mehrere-monate-dauern

[@julianegner5997]

Germanys rail system used to be as good as switzerlands up to the 80s. But then the "privatisation" was started and the Deutsche Bundesbahn became just the Deutsche Bahn - and since then, too many "saving money" occured and now the system is nowhere near as good as it was, regular delays, broken tech...

[@rustysworldofentertainment850]

@@SwoleakhulTheBlind That depends on your definition of high speed. Here in Australia, with journeys that could be thousands of kilometres long, your train might reach 160kmh for a little while until buckled rails, level crossings, freight trains and twisting sections of track slow it down (and sometimes make your train stop). 900km Melbourne to Sydney takes 10 3/4 hours. You should appreciate what you've got, and having come out of the GBT at 250kmh I can assure you Swiss trains are plenty fast enough.

[@kennichdendenn]

@@SwoleakhulTheBlind Japan has a lot of hills, I'll give them that. But I'd argue Switzerlands geography is even more challenging, making high speed even less viable. Also Switzerland is a lot smaller.

One of the tunnels in the Kurobe rail system in Japan is so close to lava pockets that it has to be water cooled, and petrol-driven vehicles are banned in there. When built, the rock surfaces were hotter than 100 °C. You can apply for a yearly lottery where the winners get to ride a train through that tunnel. The Kurobe network was built to allow the construction of several hydroelectric plants in the 60s. It has many interesting quirks and solutions to local problems. In the summertime, tourist trains run from Unazuki Onsen up the Kurobe Gorge to the top station, but the rest of the network is closed to the public. Well worth a visit.

"The firefighters need to be able to reach any point in the tunnel within 45min". Dame that's a really long time, I honestly expected much less. A lot can happen within 45min

This was SUPER interesting. I would really appreciate a much longer, documentary level presentation on the same subject.. Thanks!

An incident happened today in this tunnel nice timing. A train got stuck for 6 hours inside.

Every time I see a new video from Tom, I share it and tell all my friends. Thank you, Tom.

Thank you once again Tom. I have watched a lot of your videos and I know I will always be able to dip in and find something interesting and well presented.

I rode through the tunnel twice (once each direction) and this video reinforces what an engineering marvel it is.
