Posted by JOE @ NYCMTS - NYCTMG on Mon Aug 9 18:36:40 2021, in response to Re: EXclusive! Tuscarora Almanac for August 4 Text and Photos LIRR MP-41, posted by Avid Reader on Sun Aug 8 09:55:23 2021. Hello Guys -- Some CORRECTIONS about the posting above stating "The LIRR MP-41 cars and IRT Gibbs Hi-V Cars could "technically" MU together. That is incorrect -- see below -- Jeff Hackner (aka "Jeff H" here long ago) wrote me back in 2005 about the MP-41 and IRT Gibbs control and coupler differences - his copy-pasted comments below (quoted) ...."Joe, The MP-41s had Westinghouse type AB control with 7 point jumpers and 14 volt battery. That would have been compatible with the BRT gate cars but not any of the IRT equipment, which was all high-voltage GE Type "M" at this time in history..." ...... and ...."Joe, The IRT and BRT both used Van Dorn couplers at this time. Later (post-1912) the IRT began to switch over to tight-lock automatic style "J" couplers. My data on the MP-41 indicate it used a Tomlinson style coupler, and would not have been compatible with either IRT or BRT rolling stock, although an adapter could have been used...." Now, what I (Joe F) myself know is that the first couplers on the LIRR MP-41 Gibbs cars when brand new, delivered, were in fact, Van Dorn Link and Pin types just as used on the first IRT Subway Cars and IRT EL Gate Cars. Complete with the dual heavy steel safety "joiner chains" between cars in event a VD coupler link or pin snapped (broke). Chains would keep cars attached together and not rip apart air hoses. The LIRR soon changed over to safer Tomlinson Radial Couplers -- a heavier and more automatic type coupler -- eliminating the safety "backup" chains. Also, re: Gibbs cars operating on IRT subway lines -- some slight clearance problems were discovered, because of the following info provided by Nate G (aka formerly "Bronx Boy" here) who asked me to submit it here at sub chat: ...."Joe, would you kindly post this below for me on sub chat.".... ...." What all this sub chat posted information fails to say is the MP41’s trucks were mounted a bit further inboard to clear the drop steps at the end vestibules. And the end pilot grill. Because of this the cars would not be able to run on the IRT as they would not clear the curves at various locations. If they were able to the IRT would have purchased them and modified them to use on their lines. The LIRR really did not want them, once they changed to the wider longer MP-54 MU Cars. The cost of moving the trucks, kingpins and body bolsters forward to the IRT wheelbase positions and the electrical, brake, air and other things were just too expensive and not practical.."...... regards - Joe F |
