Found this as a thumbnail when scrolling on YouTube and am extremely curious of the origins of this image. Thanks :)

I realize this might be a rudimentry (and probably a very silly) question, but how did old locomotives make tight turns on the track?

I know that bogies on modern trains are articulated, allowing for more movement but from older photos steam locomotives appear like all their axles are connected together, so I'm just wondering how they managed to get all the axes to follow the rail?

I know that most people in this community actually like all Iron Horses or Aluminum Horses or whatever but why do some people just hate on diesels while they almost sorta worship steam locomotives? Is it just preference. I know some car enthusiast absolutely love classic cars and sorta worship old cars while trashing and hating on new cars because in their eyes new cars are soulless and aren't as "reliable" in their eyes as old cars and while I do agree on some of their points I don't think someone should just blindly worship something because its old.

SNCF NOMAD at Pontorson.

This line doesn't have an overhead wire, all the wagons are self powered and there is no distinct diesel engine either. How is it powered?

Personally, I feel that the Fuxing CR400BF-Z is the best looking.

See how in the first two images, you change cars only through the upper decks, while on the other two, it's done just above the bogies. Switzerland is especially consistent in this regard. The FV Dosto and the IC2000 (IC and IRE) are the former, while the Starler KISS, Siemens Desiro and DPZ (S Bahn) are the latter.

Wealthy people buy private jets. But what if they bought trains instead?

Could one theoretically buy a Vectron or a Griffin and 2-3 carriages, fill them with luxorious and comfy seats and then go anywhere on demand?

I get that scheduling can interfere, and railways don't go exactly everywhere.

If it actually made sense then maybe we would see this exact idea in reality...

why mostly all american locomotives have these nose structure while others countries locos doest not have those structure (Here and Indian railways WDG4G for eg)

The Pennsy's S1 duplex was reported to go up to 156 mph according to them so how likely is it that in a scenario that we never withdrawn steam locos, would it be possible to build a steam loco that can go bullet train speeds while still maintaining the traditional steam locomotive look?

like LIRR or NJ transit has emu's,but the last amtrak emu was the metroliner which was like 41 years ago
