The problem with the Pioneer III trucks as with the General 70s which were similar trucks installed on 4 IRT R-29s was that not only did the TA order insufficient numbers of cars so equipped but didn't eve require that all of the cars so equipped be kept together in the same train. As a result 2 cars with the lightweight trucks in a train that had the remaining cars with standard heavyweight trucks made for a poor quality ride. Had the TA ordered 10 cars with each respective type of experimental truck and required that all those cars be kept together in a solid train, the results might have been entirely different. Compounding the situation was that due to certain mechanical problems totally unrelated to the trucks, those 4 cars were held out of service for extended periods of time and the "cesspool of incompetence" that comprised (and still does to a large extent today) upper TA management erroneously concluded that the down time for these cars was "obviously" due to the failure of the trucks and declined to consider any futher orders of non standard trucks. A similar situation occurred with the R-46 rockwell trucks. There was nothing wrong with the truck design per se, but the TA's engineering staff again erroneously specified trucks that were incapable of withstanding the stresses present on the NYCTS and thus mistakenly jumped to the conclusion that the truck design was inherently faulty and overreacted thus setting back truck development for the next contracts of cars until the NTT experimentals of the 1990s. |
