For starters the following trips have been really slow and a problem
BxM1
1:15pm southbound (weekdays)
1:45 pm southbound (saturdays)
11:10pm northbound (weekdays)
1:30pm southbound (sundays)
9:30pm southbound (sundays)
BxM2
3:00pm southbound (Saturdays)
7:20am northbound (weekdays)
BxM3
1:35pm southbound (weekdays)
8:35pm southbound (weekdays)
9:35pm southbound (weekdays)
11:05pm northbound (weekdays)
11:15pm northbound (saturdays)
BxM4
11:05pm northbound (weekdays)
10:45pm northbound (saturdays)
10:30pm northbound (sundays)
BxM4s are the worst of them all, going extra slow while carrying the least amount of passengers
