In todays world of being green how could they even think of stopping the train?

The MTA offers basically no service and therefore people don't ride the train.

The 4:30+/- Cannonball on the Montauk Branch is used by many riders but even that line is poorly served.
Look at all the buses that run into the City. I believe they get subsidies? If they do they should be dropped and the funds used to support the railroad.
