[quote]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 [/quote] Ed, I think I remember this coming up before, and if memory serves me well, your assumptions are pretty much right. I remember it because mention was made that there were no pins, nuts, etc., and gravity was all there was holding it all together. If I'm wrong, someone correct me. mike
