When I started working in a municipal engineering department in the mid-1960s, vitrified clay pipe (VCP) was used for sanitary sewers and probably had been for decades since it is resistant to acids and sewage . . . VCP has a bell on one end with a rubber gasket but I wonder if it was ever shipped by rail.There exist photos, I think at CSRM, of this pipe loaded in box cars.
