In 1971, the RF&P put an E-unit powered passenger train on the ground after they sent it over skeletonized track with no speed restrictions! The NTSB reports of the 1970's are a litany of track woes.What these derailments showed was that a threshold had been not only been reached but exceeded. This threshold was tied to locomotive weights, speeds and track conditions. The railroads wanted heavy six axle locomotives: why else would the SP run a nine month test? They also speak glowing of all the advantages of the HT-C truck in their report. They also wanted to at least maintain the speeds they had. The solution then was to fix the track and specifically how it was regulated. |
