Why do so many large railroads (ie,class I) flat out refuse to let rolling stock that has friction bearings, from operating or (at the very least) being moved across their system(s), even if the equipment is maintained in a better condition than roller bearing items of the same type/vintage?I appreciate all insight, -- Thanks in advance!
Friction = heat Heat = fire possibility Fire possibility - liability of railroad Another item to consider -- roller bearings have been used for so long, I don't think there's anyone left of any railroad that knows how to repair friction bearings.
It's the law. More properly said, cars with friction bearings cannot be received in interchange. This restricts them to home lines. The only time you're likely to see one is on a piece of vintage rolling stock. Outmoded and, frankly, dangerous. They are also susceptible to vandalism. So, no matter how carefully maintained, it will likely never move off of the tracks it now operates on. There may be dispensation of some sort available for a one time, one direction move, but I wouldn't bet on it. So, its gets transported piggy back or on a heavy duty, drop center, flatbed highway truck. Either way, it's gonna take some $$$.
Friction bearings are not illegal, but banned for interchange per AAR interchange rules. So the car owner can't force the railroad to take the car. Railroads could accept the car at their discretion, but lately the class I's have been very risk-averse. Probably because their railroads are darn busy. I have heard of a few interesting hospital moves of large blocks of heritage equipment including Shays on their own wheels. However this was done by someone very influential with the Class I involved, and at the least busy times (i.e. Christmas day).
They don't want to be responsible for the car if the bearings fail. Consider the cost of repairs to the right of way if they were to fail on a main line. You could pursue a damage / loss waiver clause. It sounds like you want to move a vintage rail car to another site. I envy you, I work with HO scale while you run 1:1 scale.
