Posted by randyo on Mon Aug 9 01:48:43 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. The reason for the MP41s having Van Dorn couplers like the Gibbs cars and the BRT el cars was because that was state of the art for electric MU vars at the time. As newer drawheads likr the J type were develope, the existing IRT fleet was retrofitted with them and after the deck roofers, the next order of Hi-Vs, the Hedleys had them as original equipment. As for the MP-41s being technically able to MU with the Gibbs, that was not the case as the MP-41s had the WH controller similar to but not identical to the later LIRR equipment and most likely utilized a low voltage control system with automatic acceleration. The Gibbs cars had GE high voltage controls with manual acceleration and the two were not compatible. |
