The Key device is also used by the midday scoot that only runs to and from Riverhead. The crossing gates just past the station would stay down
for the entire time the scoot dwells at Riverhead (about 45 minutes), unless turned off. Granted if service east of KO had more than 1 trainset, this scoot could serve the entire line.
As for the single car, it has been that way for about a month. The Sunday evening run out of Greenport (6:17 PM) already needs the 2nd car, this is a designated "bike train", and this past Sunday it was SRO after leaving Mattituck.
The platforms out here can handle the 2nd car, BUT only 1 door on the 2nd car can be used.
As for buisness out here, Hampton Jitney would not have paid $15 millon for the Sunrise Bus Company, if there was no demand.
The LIRR remains clueless when it comes to the needs of the East End.
