As a Rockaway resident, I disagree.
Yes, the branching A is an extreme problem. But sending all trains to a branch with only three stops instead of serving what is still a transit desert? Really? Extend the C to Lefferts for those three stops if the branching is so concerning, or do Vanshnook's proposal of having the W to Euclid, C to Lefferts, A to Far Rock. Actually, I'd do it this way:
- Astoria-Euclid via 4th Ave/Fulton LCL (for yard access)
-Bay Ridge-Broadway Junction via. Nassau/Broadway LCL. Rush hrs in peak direction extended to Jamaica Ctr with skip stop service
-Broad St-Jamaica Ctr, Express in the peak direction between Marcy Ave and Broadway Junction.
-Astoria-Coney Island via. Broadway LCL/4th Ave LCL/West End LCL
-Rerouted to 96th St/2nd Avenue
-207th St-Far Rockaway (express)
-168th St-Lefferts Blvd (Manhattan Local, Brooklyn Express)
-Rockaway Park-34th Street-Penn Station (5 morning trains, 5 evening trains). via. Rockaway express. Nonstop between Broad Channel and 80th St-Hudson St.
