It’s finishing the Montauk Branch week on the SubwayNut (from my trip to finish to the branch a couple weeks ago).
This update contains the 3 stations I visited that have more frequent service (Mastic-Shirley has 5 poor photos that I didn’t quite get to) that I consider ‘commuter’ friendly. East there are just 5 to 6 trains per day except for Seasonal Summer Extra Service:
Enjoy!
