As Joe and I both discussed in various posts, elevated 3rd rail was developed first and since the Manhattan els received 3rd rail ahead of the subway, they received what was state of the art at the time. By the time the subway construction was underway the subway type third rail and paddle type contact shoes had been developed and so that was what was installed on the subway. |
