Passenger Trains > LIRR diesel layovers

Somebody bounced a question off of me about the operation of push-pull commuter trains, one I couldn’t answer. 

The question involved overnight layovers of diesel consists, and whether the diesels run all night, shut down entirely, or have something like the periodic start/stop controls you see on newer freight diesels. 

I think I can identify where the other northeastern commuter lines have diesels parked overnight, but (embarrassingly) don’t know the LIRR all that well. Anybody know offhand where their overnight layovers are?

Oyster Bay, Port Jeff, Montauk, Greenport, I imagine.    Pretty boring, no variety

When the FA units with their 244 prime movers were in cab car service the LIRR added a large muffler over the prime mover to reduce the noise when the unit was idling at night. When they converted to either a Cat or Cummins gen set they could be shut down at night in warmer weather. ---  Ken 

Add Babylon, Speonk, and Ronkonkoma, delete Greenport from the list.
