The underruning third rail was designed specifically for the New York Central's operation into Grand Central and was originally called the Wilgus-Sprague system. The NYC felt that it would provide greater protection from accidental elctrocution and provide greater protection from snow/ice. The underrunning third rail never really caught on in North America although several European systems use it. LIRR uses a more popular overrunning third rail. |
