You have to remember, the subway or overrunning shoe has a downward action as do the El type third rail shoes. The underruning third rail shoe of the New York Central vintage electrification has an upward tension. The engineering to make the shoes compatible on either system is probably more costly than the need to actually do it.Conversion of the underrunning system to overrunning would be a monumental task. I believe that the underrunning rail and shoe is better for high speed operation as would catenary be even better. The underruning shoe has upward tension as does catenary contact. |
