I believe there are a total of eight platform tracks on two levels. Sounds a little bigger than Atlantic Terminal.
Yes, Freightguy, I was there back then, and remember well Supreme Court Chief Justice Warren E. Burger's March, 1982 opinion:
..."If it looks like a duck and quacks like a duck, well then it's a duck..." regarding the LIRR being a railroad and not some sort of rapid transit system that's exempt from the Railway Labor Act.
It was a huge blow to the State and the MTA which was banking on running it like a city agency.
