@a320lga I read a NYT's piece back in '18, this is (obv) much more thorough, so thanks!

Just to further your point on the human element, Paris RER line C's central section is mostly 60kph. It used to have _one_ very small 40kph section (at a junction west of the Eiffel tower). To avoid triggering the ATC (KVB), operators had gradually adopted a 40kph speed throughout the whole core section, just "to be safe".

The junction was redesigned to allow 60kph throughout, which helped the line's OTP.

Ever wondered why the New York City Subway ended up with so many speed restrictions, operational variability, and service problems? A long post on the history of a signaling crisis:

The PVL' s frequency is hamstrung by its passing sidings along it (see: https://homesignalblog.wordpress.com/2022/11/26/stringlines/) but is nevertheless a corridor with immense potential to develop ridership & relieve the PABT. Good to see steps, even if small, towards realizing the corridor's promise.

holiday train fun (feat. mostly trains that aren't the holiday train)
RTD is moving away from its past practice of splitting 15 minute light rail frequencies over its two downtown termini, in a move seemingly tied to the agency’s persistent COVID-era staffing and schedule resiliency problems. Having these more regular and consistent service patterns is good stuff, though it does mean that the agency will have to work hard to make transfers reliable on the shared trunk section.
There just was an hour long gap in northbound A service from Ozone Park. The crew shortage is likely the proximate cause here, but that the A’s timetable has such long branch headways, whose execution relies on a bunch of complex/fragile train/crew manipulations to work is what makes this all so fragile. More so than any other line in the system the A needs a full timetable rewrite.

Ever wanted to make your own stringlines? This blog post will show you how -- and explain some of the things you can learn from them.
