Has anyone ever seen an elevation profile of the Northeast Corridor? The whole line is fairly flat, but I'm curious what the highest points are in each state, where the steepest slopes are, etc.
Hudson or as they were originally known - North River Tunnel ramps it is.There have got to be old Pennsy, New Haven and even PC employee timetables around that probably have track profiles, even if Amtrak/Metro North ones are hard to get.
Just a guess, but my money on the steepest grades are into and out of the North River Tunnels under the Hudson and/or the approaches to the Hells Gate bridge.
