Posted by SelkirkTMO on Mon Sep 3 02:19:33 2007, in response to Re: Brake Valve pr0n Re: LIRR MP-54 #1149 and its ME-23 brake valve, posted by Bill West on Mon Sep 3 01:45:28 2007. Hiya ... the manual I have from Westinghouse (which BIE was kind enough to give me as a gift a few years ago) doesn't have the electrical wiring for that, but does show that the pipe in question is part of the equalizing reservoir "intended to minimize amount of reduction." The fifth contact is shown without any indication as to which magnet valve it operates and is a shorter leaf than the ones above it if we're reading the same photograph. From Heypaul's video, it appears to go up to the three conductor electric brake plug and therefore could INDEED interrupt the emergency wire with the plug is inserted.Cryptic mention of this being part of the design appears to be there with this wire intended to pick up an emergency application if it is due to a fault somewhere. But from there, can't quite figure out what is meant since there is no wiring diagram or schematic in the manual I have. This manual goes into a great deal of detail over the orifices within the air sections and slack adjusters and the piping of the brake lines, load valves and magnet valve sequences, but very little as far as the electrical bits. :( But you might be right about that ... but I suspect that fifth contact only existed where the electric brake plug was installed and was external where it wasn't. |
