NJT schedules are ridiculously complicated. On most lines, there's only about 2 trips for each distinct stopping pattern -- a level of rider-unfriendly complexity that sits atop the system's complete lack of consistent scheduling and infrequency.
For reference, the _most_ complicated NYCT service (the 5) has 10 trips per distinct stopping pattern -- and on NYCT, most of the stopping pattern variation is at the ends of the line vs through the heart of the route as on NJT.
(Inbound = southbound, outbound = northbound for the NYCT chart; both analyses of weekday schedules only)
Also, at the top of this thread, in what I now see is an ineloquent tweet, I meant to write “total lack of consistent arrival times” ie no clockface predictability in arrival times.
