Book Description

The derailed car then scraped along the north side of the locomotive and along the north side of the 5 VIA coaches. [...] At the time of the accident, the temperature was 22°C, the skies were clear, the visibility was good, and the terrain in the vicinity of the accident was generally dry. [...] From there, the marks continued eastward for about 60 feet on the base of the rail, on the tie plates and on the ties, before impacting the planks of the private crossing at Mile 153.9. [...] The sum-of-pairs refers to the sum of the height measurement for 2 constant contact side bearings either on the same truck or on the diagonally opposite ends of the car. [...] The investigation determined that development of excessive truck hunting was likely influenced by the type of car, the speed of the train, the worn condition of the A-end CCSBs, a truck type with low warp stiffness, and non- condemnable, slightly narrow gauge and multiple cross-level perturbations in the south rail.
