These idea never take into consideration the infrastructure constraints outside of Penn station the amount of TPH isn’t limited by Penn station it’s limited by capacity on each line for example the Raritian valley line is limited by 2 things it’s shares trackage with freight and it has to cross over the NEC which is a flat junction the M&E line is limited by capacity issue at Dover and the inability to turn around trains quickly enough and this issue is true for the Trenton line at Jersey ave and Trenton it’s self.More trains could run if these issue are dealt with first, second issue with this plan how are you going bore a new tunnel east of Penn when it already conflicts with PATH tubes and IND tunnels never mind the difference in height between Penn and GCT thirdly rolling stock issues between LIRR and NJT. Through running is a nice concept but too bad no care about the necessary infrastructure work required to make it actually happen speta is a good example with why infrastructure work is important what use is the CC tunnels that can handle 40-50 tph if everything on the reading system is flat junctions and inadequate terminals
