Back in the days before SecJ, I had to take the PATH to get from the NEC to Hoboken to connect to my train north. Although I liked taking the train in general, I was pretty frustrated how a one hour car ride became a 2-3 hour triple or quadruple train ride. One thing that always struck me was my perceived sluggishness on the Harrison/Journal Square segment. A distance of 5 miles takes about 9 minutes according to the time tables (I know that it can be shorter sometimes in practice). Does anyone know of any ways in which the PA could speed this up? Will the new signaling system that they are installing help? New trackage?
