History of Railroad Safety - Spotlight on current derailments

[QUOTE="Astronuc, post: 6867386, member: 15685"] I found another link to a CBS affiliate - with conflicting information on that derailment. The CBS article mentions 8 cars are off the tracks at the rear of the train, but other articles state 21 cars derailed, so presumably, 13 of the derailed cars stayed on the tracks. It looks like a unit train of autoracks, which seem to be bilevels carrying SUVs and pickups. [URL]https://www.wlky.com/article/train-carrying-cars-derails-hardin-county-glendale-kentucky/43340951#[/URL] No hazmat was involved, but in the middle of town, one autorack hit a building and another autorack his an occupied vehicle; one person had minor injuries according to police. It's odd that rear cars would derail, unless the didn't have brakes applied and their momentum cause them to pivot off those case that were stopped or braking.Run-in forces have been a problem for decades. Back in 1974, D&H had a train that went into emergency when center sill and draft gear failed on car 4 (couplers between cars 3 and 4 separated). The locomotives instigated emergency stop, but cars from 4 on back didn't stop, and they ran into the front end on a 3° 30' curve. The lead coupler on car 4 was add an odd vertical angle, since the car was heavily loaded, and apparently it was pushed to the point the outside rail was pushed out of gauge, as well as being overturned for some length. NTSB/RAR-83/05 - [URL]https://rosap.ntl.bts.gov/view/dot/45449/dot_45449_DS1.pdf[/URL] I believe there was an issue with the track in that the rail was not properly secured. D&H was struggling financially (fuel prices greatly increased due to OPEC oil embargo), and like many railroads at the time, they deferred maintenance on the track, structures and cars. The car in question was only 5 years old. It had a capacity of 264k lbs. [/QUOTE]
