I don’t know. Except for yard moves, I don’t see where it would have been necessary although it may have been possible. Except for C units 1500 and 1501, AFAIK, all the Cs had their original BU master controllers replaced by ones removed from the unused cabs of the steels when they were unitized into B and BX units. The Qs retained their original BU controllers and the BUs and Qs only had 2 points of power series and multiple while the Cs had 3 switching series and multiple. The reason the Qs and BUs lacked a switching point has to do with their dead man’s button. As built, the master controllers had all 3 points of power, but when the handle was released by the M/M it only sprang into the off position but did not apply the brakes in emergency like a true deadman’s feature. In the 1920s, the state passed law requiring all electric self propelled cars to have a true deadman’s button that would apply the train brakes in emergency when released. To accomplish this, the BMT eliminated the switching position by making it a coasting position and adding an air valve which would apply the brakes if the controller were not kept at least on that first point. As I write this, I am thinking that since Cs 1500 and 1501 which had no switching position often operated in trains with other Cs which had a switching position, then it’s highly likely that a C could MU with a Q although as I mentioned before, except of yard moves, there would really have been no reason to MU them since they never operated on the same parts of the BMT during their service life. |
