I know right they are just trains to provide services for us so it really doesn't matter which type train to use or ride. All train models experience some kind of delays just like cars on the street. All of the train cars actually are good otherwise they would not be using in the subways for us to ride.
NYC including All Five Boroughs would be a complete disaster we would depend on Local and Express Buses, Taxi, Cab and Van service, and use the Metro North and Long Island Trains.
Weekdays normal service SB going Express in Manhattan could use the merge crossovers south of 57 St-7Av and NB merge to Local tracks instead of in-between 34 St and 42 St. The and could handle 49 St without .
So riders have to wait at least every 30min for a train to show that is unbelievable. And then on Weekends they always have trains sharing the same tracks which make it worse. Instead they should consider cutting one of them or do a short turn.
Traveling from Bronx to Far Rockaway or Five Towns is a long hard travel either way and there is no market for a one seat ride because not everyone are traveling like that.
How about 207 St and Far Rockaway, 207 St and Rockaway Park overnights Shuttle between Broad Channel and Rockaway Park, 168 St and Lefferts Blvd overnights Shuttle Euclid Av to Lefferts Blvd.
