I also love this visualization and remember being blown away when I first saw it!

Two notes: 1. These “stringlines” are also known as Time-Space Diagrams in the transit industry, and they’ve been around for a while. e.g. https://www.researchgate.net/figure/Time-space-diagrams-of-t...

In fact Vibien cites as inspiration the official NYCT stringline paper: https://www.worldtransitresearch.info/research/5936/

2. I’ve noticed that at least on the A, the viz is inaccurate? It’s missing a lot of trains.

Found a nice video digging into traffic time-space diagrams: https://youtu.be/E_tk6BGhYDE

There's a nice a-ha moment when he shows aerial photographs.

I knew he cited a NYCT paper on the page itself, but I've never seen the paper so I didn't know how similar they were. Regardless, making this available to the public is laudable in-of-itself. Thanks for the sources, will check out later!
