As Summer rolls around, the LIRR should offer a first-class car, cafe car, and more cars on beach trains for vacationing new yorkers who want a cheap beach trip on the Montauk Branch
it helps long island communities, it helps new yorkers, win-win
it doesn't have to be every train, it can be a limited service. I'm sure the conductors know the busy trains. Advertise 1st class as a limited bonus with 1-2 seating. The Boston Cape Flyer is a good example, charge hotels to bundle their tickets with the train on booking sites
