Why does everyone want the Kings Hwy F's to run express? There are two reasons to run expresses:

1. Cut travel time short for riders at the end of the line.
2. Intermediate express stations with High ridership.

Generally, expresses run further out on a line than locals because of reason No 1. The two exceptions to this rule, Brighton and Eastern Parkway, short turn the expresses because the existing infrastructure forces this, but also because the express stations on these lines have high ridership (well, on Eastern pkwy, also because everything can't fit on the local tracks and Lexington trains have to get on the express tracks anyway). By making the express the Kings Highway train, you render reason #1 moot, since passengers from Coney Island through avenue U would only have local service. They could transfer to an express, but if it wasn't going to beat the local to Jay, then why change? Additionally the inner local stations wouldn't get the benefit of emptier trains, because locals would still be arriving with passengers from Coney Island, and to add insult to injury, there are now fewer trains. I don't see what the big deal is with making Kings hwy trains the locals, it's almost a 1:1 ration of KH trains to CI trains.

The more I think about this, the less and less sense it makes. The one advantage for the MTA would be fewer trainsets. Short turning the local would mean that you could reduce service on the outer ends of the line, but make up for it by running trains express. This works well with the A and C trains. This is helped further having yard capacity at the end of the local line. The C would make less fiscal sense if Pitkin Yard were instead located in the Rockaways. But that is the exact scenario in place on the Culver line. Since Church has almost no storage capacity, at the end of the day, every local train that drops out at Church would have to deadhead to Avenue X yard. In the morning, they would have to do the opposite. So, unless the expresses can generate enough riderhsip from stations south of Church, then there's no reason to run the service.

If there were ever another branch connected to Culver, or if stations from Church south experienced a ridership boom, then that would be reason to run an express on the line, but until then, I think it's a non starter.
