The MTA has issued a weekend service advisory for the F train, which may affect travel plans.

A Roosevelt Island resident tweets that the Tram should also extend it’s weekday rush hour schedule to 11 PM because of overcrowding too.
@Rooseveltisland It’s time the tram extends its rush hour service, 8:30pm-9pm even 11pm it’s still packed. Commuters getting left behind.Stephen Ward (@Traintheworld1) April 21, 2016
It’s a good idea. RIOC should do it.
