The R-16s were the first mainline cars to have all electric door operators as opposed to the electro - pneumatic door engines on the R-10s and older equipment. The first cars to have all electric door operators were the R-12s and I recall that when they were on the 3 Av El in their last days, there were always battery problems. The R-12s through 16s had door equipment manufactured by the Nat'l Pneumatic Co. while the R-17s through 22s had door equipment from the Consolidated Car Heating Corp. It may have been that Consolidated made a superior product. The IRT cars also operated on lines that a great deal more underground operation that the R-16s on the Jamaica Line and that could account for their superior performance since they were underground more and exposed less to the elements. That being said, it would be interesting to see what, if any, problems the R-12s through 15s had when they were first introduced on the Flushing Line. Mechanically and electriclly with the exception of the door operators, they were more like the R-10s so they most likely performed better than the R-16s. Also, with no backup fleet to bail the line out or no easy way to swap cars between lines, the car maintenance force at Corona Barn had more of an incentive to keep the cars in good order and do what was necessary to minimize equipment failures. |
