I think the Belmont station is now seasonal, from LI you need to xfer in Jamaica and if you survive, you can then go to Belmont.
Sadly, the Citimorgue and Belmont sites should've been used for a Jets stadium too, but Woody was such a dope, he thought he could get a stadium on the west side for some odd reason, complete with no parking. If he had used his pull and noodle, he could've landed a spot closer to the team's fan base, Instead, we have Giants Stadium 2 - Electric Boogaloo.
The LI area needs an airport and an arena, sadly, it's such a cluster out there, nothing will ever get done.
