Over on the Avelia Liberty thread a question was asked about the state of the Keystone catenary and the electric capacity of the 138kV transmission system associated with the route. Has Amtrak given up on the replacement of the 1ED and 2ED transmission circuits from Zoo to Earnest? The Wikipedia article on the 25Hz transmission system and some of the threads on this forum have strongly implied that the lack of capacity of these circuits and the loss of the Trenton Cutoff circuit(s) to transmit power from Richmond are contributors to the limited electric capacity of the Keystone. What are the practical limits of distributing power from Safe Harbor, Lamokin and Richmond to the Keystone transmission lines and the catenary?
