- A recently-posted article discusses the use of Cor-ten steel in RR feight cars,
- especially hoppers, noting that they appeared to be painted, depsite the
- special oxidation properties of Cor-Ten (it rusts, of course, but without
- flaking off in big pieces so that it forms a self-protecting coating like
- many other metals).
-
- I cannot provide a definitive answer, but I can distinctly recall seeing
- _unpainted_ Cor-Ten hoppers in the south on a train trip in 1971. I was on the
- L&N primarily, so I believe that that was the owning road of the cars.
- They were clearly _unpainted_ cars, as opposed to _unmaintained_, because
- their entire surface areas had iron oxide (i.e., rust), except for the
- lettering. Moreover, the surface had the appearance of other Cor-Ten
- applications I have seen (smooth and powdery without blisters or flakes).
