This second pilot-version, which has added Bedford Park Boulevard as a stop, began on October 26th and will run until December 11th. It's the truth.
From 7am-8:20 am there is a diamond-4 express train that runs from Woodlawn, Mosholu Parkway, Bedford Park, Burnside, 149th, 125th, 86th, etc. With 86th as my destination, the elimination of 8 stops or so makes a real difference. Another bonus is that the train is less crowded without the more local commuters.
I hope this pilot program becomes permanent. Next thing to do would be to make a PM 4 train express with the same stops - now that would be amazing.
In any case, I'll certainly call the MTA to express my gratitude and ask for this glorious express 4 train to become a fixture of the incredibly overcrowded green line.
