QUOTE: Originally posted by mudchicken For openers: (1) If the cars are loaded, the retarders may not slow them down enough before they "hard couple" down in the bowl. Laws of physics (inertia) in play here. (know of incidents at Pueblo where the retarders failed, heavy cars rolled out the other end (south end) of the yard, only to be dumped on the ground by a switch point derail [gravity works!]) (2) some have a secondary air line for automatic dumping that is not to be messed with up high where a switchman might not see it. (3) rotary coupler assemblies could be damaged or misaligned, depending on the type......
QUOTE: Originally posted by mudchicken (1)If you shift the mass in some of the newer aluminum coal-gons (coal car), a massive enough impact will "break the back" or warp the body of the coal car. If you get two or three cars together going over the hump, then WHAM! The cars continue to get heavier and some dowty retarders won't slow down the moving mass. Some car owners see humping as contributing to a shorter service life for the car due to impact loading and metal fatigue. Anyone working in a hump yard has seen the results of overspeed impacts in the bowl - sooner or later something either crumples / breaks or the lighter cars get pushed up & off the track. (3) coupler type and the bearings in the rotary assembly are different in many of the solid bottom/ rotary coupled cars (where's the carknocker on this forum when you need him/her around anyway?) Wish we could give you a more complete answer. This is just what I've been exposed to over the years. mudchicken

QUOTE: Originally posted by edblysard You missed one. Loaded coal car are often loaded above the top, remember seeing that little mound of coal sticking up above the rim of the car top? In a hump yard, when the car hits the standing cut of car(bumper) all that coal shifts. You can get a pretty good pile of it for free. In the aluminum cars, when that much weight shifts, it can distort the car body. We flat yard switch, which in some instances can be harder on cars than a hump yard, and trust me, with the coke and coal cars, if you need a little coal for the barbque pit, it ait all that hard to "spill" some out of the cars! And you dont want to beat up the older bottom dump cars too badly, they will dump their contents really quick if the door lock breaks. And a hopper load of coal in the middle of the tracks slows things down real fast! Stay Frosty, Off to work Ed
