Since it is Friday it must mean another weekend without full F Train subway service for Roosevelt Island. Just like last weekend there will be no Queens bound F Trains stopping at Roosevelt Island but there will be Manhattan bound F trains service from Roosevelt Island. These service interruptions are scheduled to continue for the following two weekends. Here is the MTA F Train weekend subway advisory.
Queens-bound trains run on the V from 47-50 Sts to Roosevelt Av
Weekends until Feb 4
12:01 AM Sat to 5 AM Mon

How does this affect my trip?
~~ For service to 57 St, take the F to 5 Av-53 St and walk.

~~ For service to Lexington Av-63 St, take the F to Lexington-53 St and transfer to an uptown 4 or 6 to 59 St and walk.

~~ For service to Roosevelt Island and 21-St Queensbridge, take the F to Roosevelt Av and transfer to a Manhattan-bound F.

~~ For service from 57 St, Lexington Av-63 St, Roosevelt Island, and 21 St-Queensbridge, take a downtown F to 47-50 Sts and transfer to a Queens-bound F.

Why is service being changed?
We are making electrical improvements to ensure that trains continue
to operate safely along the F line.
There is good news however. I have recently discovered through a well placed secret source an experimental transportation system that the MTA and RIOC have been working on with a high-tech Japanese company to get Roosevelt Islanders back and forth across the East River. They hope to have it ready when the Tram is taken out of service next year but may install it sooner if subway service continues to be so unreliable. Here it is. What do you think?If it works on Roosevelt Island, the next phase of service will include the Toll Brothers North Side Piers Development and Schaeffer’s Landing in Williamsburg both of which are seeking ferry service.You Tube video link is here.
