It's a good suggestion. Besides things like Hyperloop and such, even with today's train technology, a fast train (TGV, Pendolino, etc) could connect Pittsburgh to NYC in 2.5 / 3 hours. Unfortunately it would take 20 years to build it.
Pennsylvania became an economic powerhouse because of the railroads, but without them it's just a sad shadow of it's former glory. If someone took the lead on rebooting the railroad industry in PA it would reboot the entire economy of the state.
