Read recently that since the rebuilding of the Culver Viaduct, there has been serious consideration to add express service to that line. As of now, the G runs local to Church Avenue, but it doesn't go to Manhattan. People who use the local stations would not want to lose a one seat ride to Manhattan. Here's what I thought would be a practical idea to add express service to the Culver Line, but also not take a one seat ride away from those who use the local stations.
There would be 4 services on the line. The F operating at all times, the G operating at all times, the <F> operating weekdays in the peak direction, and the V would be brought back to run all times except late nights.
The F would be the main service operating at all times on it's current route from Jamaica 179th Street to Coney Island Stillwell Avenue. It would run express from Jay Street to Church Avenue, but skipping Bergen Street so the lower level doesn't need to be rebuilt which reduces costs.
The G would remain unchanged.
The new V would be added running fully local from Forest Hills to Church Avenue all times except late nights. The M would be changed back to its original brown color and original route. At times when the V was not running, the F would run local.
The <F> would run weekdays in the peak direction from Jamaica 179th Street to Coney Island Stillwell Avenue. It would run express south of Church Avenue switching to local at Kings Highway. Even though the express track continues, it is the last station with 3 tracks. To ease congestion at Stillwell Avenue, some local F trains would terminate here and short turn on the express track. The express track could also be used to store extra trains to be used during rush hours.
Does this sound like a plan that could be used to add this service?
