There are more things that need to be done but that will help. I am guessing that when all is done, trains will be able to run faster - though that includes the results of rebuilding the existing 2 track tunnel and 2 tracks between there and Newark (assuming that's part of the project). Eventually, depending on who you believe, we SHOULD build a connection to GCT, presumably LIRR level (because of the type of 3rd rail it uses - or the main levels with CAT) for through running, also have Amtrak able to go to Long Island along with NJT, and LIRR to NJ. Lots to think about here. Maybe added tracks at Penn. Etc.
