I don't know what I was thinking, but i was looking at a 2004 subway map (still during bridge reconstruction) and had an idea for a new line/ service.
Brighton
Culver.
This would be changed once the is extended to 96th Street.
The would resume service, operating weekdays from Astoria-Ditmars to Brighton Beach (Queens Lcl, Manhattan/Brooklyn Express) It would run the same hours as the .
The would then be relocated to the Culver Line. It would go to Kings Hwy (peak direction express) Rush Hour/Midday. Evenings it would terminate at 2 Av.
