looks like extremely little service management is happening to control any of the resulting wait time impacts. 2091 just gets later and later...

A lot has happened to PATH in the past 25 years -- 9/11, major construction work, COVID, etc. But consistent across all of these events have been ensuing reductions in off-pk service levels: since 2005, the number of PATH trips crossing the Hudson on Saturdays has fallen by *50%*

Also potentially an opportunity to do some honest to god freight planning and reroute some traffic that currently uses CHI-STL either away from Chicago entirely or away from the pax line. Having the fmr. wabash in the picture helps!

Going to publish a much longer look at bus operations soon, but it is just _incredible_ how significant the trip-level effects on performance are, even on fairly frequent routes. Two examples from the MBTA's network:

Perhaps a NY-specific phenomenon, but you can find a lot of remarkably clear-eyed writing about the impact/risk of declining off peak ridership in contemporary reports on commuter rail viability:

It's a lost nuance in transit's financial history, but these observations on the relationship between off-peak demand and overall profitability remain extremely relevant to system design discussions today:

It def breaks down south of the Carolinas, but on the whole I think the mappings end up decent in the East, so long as you're willing to be a bit loose about which level of aggregation you're using. Maine doesn't need this level of subdivision, but the rest of the Mid-Atlantic + New Englnd is ~solid

imo we should embrace environmental-historic contingency and re-map the states based on watershed boundaries. for the most part, it works incredibly well.

In 2004, when Jersey City was ~20% smaller:
- PATH ran the normal weekday service pattern (at 15 min frequencies) on weekends, plus 10 min midday service on all lines.
- HBLR ran 15-minute headways middays & weekends (vs 20 now)
- PATH ran the normal weekday service pattern (at 15 min frequencies) on weekends, plus 10 min midday service on all lines.
- HBLR ran 15-minute headways middays & weekends (vs 20 now)

I am forever grateful for my family’s patience. I am reminded that I also dragged them to bombay beach that day

One map I have grown to hate: this one. Nostalgia for all the lost intercity trains often masks the fact that those services were dinosaurs. Some stats:
- In 1954, 70% of e/b trains on the PRR from PGH left PGH 10p-5a
- In 1960, 50% of the Santa Fe's Chicago-KC trains arrived in KC 10p-5a
- In 1954, 70% of e/b trains on the PRR from PGH left PGH 10p-5a
- In 1960, 50% of the Santa Fe's Chicago-KC trains arrived in KC 10p-5a
