With a recognized need to either rehabilitate and/or replace the largest 25 Hz system in the US (New York to Washington rail corridor), one is faced with technical, operational, economic and political issues. Highlights are presented of some of the major issues which bear on the question of which system, 25 Hz at 12 kV or 60 Hz at 25 kV, to adopt. The role played by the utilities is examined along with operational considerations. Economic considerations are also outlined.<>
