Posted by randyo on Fri May 1 15:19:39 2009, in response to Re: Covered/uncovered third rail, posted by Jeff Rosen on Fri May 1 14:44:58 2009. The problem was that the elevated "gravity" shoe came earlier and the paddle type shoe which allowed for a covered 3rd rail came later. There were portions of both BMT and IRT els where the paddle type shoes wouldn't clear, most notibly the Myrtle Av El between Bway and Bridge St. The TA solved the problem of 2 types of shoes on Myrtle by providing special ramps at the entrances to those stations that lifted the shoes above the portions of the girder work where they wouldn't ordinarily clear. |
