@wmeehan @ndhapple I think the real dark horse candidates for messiness are:
- Stillwell (low capacity/holdouts)
- Nostrand (peak service levels here are lower than you think)
- Forest Hills (usually congests back to ~63rd drive at peak; all day 20tph into here will need some serious ops reform)
- 145/BPB (both north ends of the B are single pocket terminals, one of which backs onto a major junction. Not a recipe for fun)

@wmeehan @ndhapple Yeah Dekalb peaks at 20 today but it’s definitely not sustainable as an all day service level.

@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.

@jackharman yeah it’s honestly wild — a just incredibly blatant case of institutional coordination/oversight failures

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.
Stringlines!
