I am happy that you did not mention Mag-Lev in your editorial on high speed rail ("Working on the railroad," Jan. 23). The proposed Baltimore-Washington Mag-Lev would be a disaster partly because it would be incompatible with all existing railroad track and trains.
On the other hand, high speed rail is completely compatible with our existing system. Although new track would be needed in some areas, much existing track can be upgraded to the higher standards. Trains can use existing track to enter cities and stations.
