I will visit Sofia next Weekend and i am wondering how often and what lines are the unmodernized 81 71 trains driving?.Otherwise If the unmodernized 81 71 trains get retired will there be an heritage train preserved for heritage rides in future like in prague and warszawa?.

Since the Blue Line runs 24 hours on Saturdays, I took the opportunity to snap this photo while waiting for the train at Tucuruvi station last Saturday.

The only station on the line with side platforms

Was transferring from the Amtrak station in Alexandria to the metro. Lots of construction work any improvements on a future better transfer than what there is now?

I've been building an app called Belowtown that shows the whole NYC subway in 3D, sitting under a photorealistic version of the city. You can fly down through the streets and see how the lines stack on top of each other at junctions, how deep the newer tunnels go, and where lines climb up onto the else in the outer boroughs. Trains move live off the MTA's realtime feed.

Depth is stretched 3x by default so you can actually see the layers (you can turn it down).

It's in beta right now and I'd love people from this sub to try it, especially if you know other systems well. Tell me what looks wrong, what feels off, or what's missing compared to the metro you ride. I don't live in NYC, so outside eyes really help. If this comes to fruition, i would love to expand it to other cities.

Anyone who sends feedback gets 3 months of Plus free when it launches. Happy to answer questions about how the track depths were figured out! Make sure to check junk folder for the invite link in your email if you sign up to test the beta.

Kyiv’s metro is way more than just a daily ride — it’s a total engineering marvel. You’ve got crazy deep Cold War stations doubling as shelters, a cool mix of retro and modern trains, and awesome bridges going right over the Dnipro River.

For the transit geeks here: what blows your mind more — super deep subterranean engineering or dramatic open-air river crossings?
