Here's one of my old proposals, but I revised it this time again. It'll go into effect after Phase IV of the Second Avenue Subway is completed:
There will be a new subway line under Steinway Street to 20th Avenue, branching off the and after Broadway. The new service that'll use this line will travel via the after 36th Street and veer off onto Second Avenue after Roosevelt Island, but will continue to Brooklyn via Hanover Square and the Montague Street tunnel instead of going across the Manhattan Bridge. Here are my plans:
Plan A:
Weekdays: between Steinway-20th Avenue and Bay Parkway via 63rd Street, Second Avenue, Fourth Avenue, and the West End Line
Weekends: between Steinway-20th Avenue and Hanover Square via 63rd Street and Second Avenue
Late nights: shuttle between Steinway-20th Avenue and Steinway Street-Broadway
Plan B:
Weekdays: between Steinway-20th Avenue and Kings Highway via 63rd Street, Second Avenue, Fourth Avenue, and the Sea Beach Line
Weekends and late nights: Same as Plan A
In both Plans A and B, the new service will run fully local, and trains will run local in Queens during late nights. At Hanover Square a free transfer to the , , , and trains at nearby stations will be available, and south of the Steinway Street station a new layup track will be built alongside one of the existing tracks for nightly shuttle trains.
Which plan is better: A or B?
