F train changes bring limited rush hour express trains

There is now limited express train service as part of new F train changes.
The changes will mean limited rush hour express trains will run between Church Avenue and Jay Street-Metro Tech, stopping at Seventh Avenue.
It's a change from the 26 stops the trains currently stop at, which is the longest local section of any subway across the entire city.
The logo to look for will be an F inside a diamond, as seen on the outside of other express trains.
