This is my first take on this particular topic/project. I have to say, this isn't that bad of an idea, but like many said it isn't for every diesel branch. Aside from the Central Branch hopefully getting electrified by the time the 2020-2024 Capital Plan is done, I am worried about the Lithium Ion batteries that we could possibly be using if this test is successful. What I do see is the following:
1.) M7 and M9 cars stopping at all Oyster Bay Branch stations.
2.) The cars stopping at all Port Jefferson Branch stations.
3.) The cars stopping at stations East of Babylon all the way to Patchogue.
4.) For the Ronkonkoma Branch, only to Riverhead.
5.) The EMU consists will be no longer than 6 cars.
6.) If successful, then the Gas Turbine GT1 cars from the late-60's will be all the more a large failure that we already know of.
Logistics are a bit of a concern:
1.) Charging stations.
2.) Track layouts since the Port Jefferson Branch East of Huntington is similar to the Ronkonkoma Branch before 2018.
3.) The length of the platforms, most of them are 2-4 cars long. Although Bay Shore, and all PJ Branch stations can platform 8 to a full 12-car consist.
4.) Obviously recycling the batteries.
5.) How much we will shrink our carbon footprints.
