"The car shops also turned out passenger cars like this Intercolonial Railroad car No. 1 of the 1870s. The decorating masters, or "trimmers," in the paint shops did superb work detailing both railroad cars and engines with many colors of paints as well as with gold and aluminum bronzing powders simulating gold and silver leaf. After the early 1880s, when many engines now burned the dirtier coal instead of wood, the colors on the exterior of railroad equipment shifted to darker shades, and less ornate and colorful details were used."--Fletcher, David H.
