Posted by randyo on Wed Sep 5 14:25:22 2007, in response to Re: controller Re: LIRR MP-54 #1149 and its ME-23 brake valve, posted by Jeff H. on Tue Sep 4 19:35:03 2007. Well, as you probaly know, Jeff, as built, these controllers did not have a true deadman's button but merely returned to the off position when released by the M/M. In the mid 1920s when the NYS PSC mandated the installation of a true deadman's button on all electric railway equipment, the BMT rewired the BU controllers to eliminate the switching position and make the former switching position a coasting position. You are probably correct about it being some sort of a kitbash and since this retrofit was done about the same time as the steels were being unitized, this part may be something removed from the steels during their unitization. |
