How does this work for say, the New York and Atlantic Railway which runs freight trains on the same tracks as the Long Island Rail Road? There are stations where a freight train passes through while a passenger train is behind it.

The LIRR is heavy rail rather than light rail.

I don’t know the regulations but that’s probably why.

You're correct. LIRR trains are built to a much heavier standard and thus are allowed on the same tracks as freight rail.

Does the locomotive weigh half a million pounds and have no passengers? Then it’s heavy rail.
