The platforms are not large enough to support people waiting at the same time as the train is unloading and are full of columns. There are safety concerns in not being able to evacuate passengers quickly enough in the event of an emergency via narrow escalators. Through running NJ Transit onto LIRR is through running AC trains onto a DC network. That is billions. In addition, nobody from NJ wants to go to Long Island and vice versa, and most NJ Trains run-through the station in the same direction already to be stored at Sunnyside. The same is true of LIRR, they go into the west side yard as a straight move. The NJ trains that don’t run to SSY are usually making use of the stub end tracks at Penn where through running isn’t an option.
