QUOTE: Originally posted by dehusman The only thing that holds a freight car on the trucks is gravity. There is a circular indentation in the top of the truck that mates with a circular casting on the bottom of the bolster. The same thing with the wheels on a modern roller bearing truck. Some trucks have a keeper block that keeps the axle in the truck, but many times the truck is just sitting on the axles. If you pick up the car, the trucks stay on the track, if you pick up the truck frames the wheels and axles stay on the tracks. Dave H.

QUOTE: Originally posted by doghouse I have a question and, more that likely, its been asked before. Plus, I was too lazy to search this thread to see if was asked before so here it goes. How and where did the term "fallen flag" arise and how did it become associated with railroads that have been absorbed into others.

QUOTE: Originally posted by egmurphy Taking advantage of the fact that this thread has come back to life, let me ask one (or two). How is a railcar fastened to the truck? I can imagine that the bolster on the car must have a pin that fits down through a matching hole in the truck bolster or something along those lines. Is there any kind of retaining washer/nut/pin arrangement to positively fasten the car to the truck, or do they rely on the pin and gravity to maintain the car in position on the trucks? Anything special about the bearing faces where the car bolster and truck bolster meet? Or just flat metal faces with some grease? Thanks Ed

What characteristics made them worse than EMD units? They take forever to load. If that's true, then what's the best loco that can load real quick, or is that just opinion?
