Sir: This may not be completely correct , but I would guess the 
railroad was trying to prevent the roofs from corroison . Soot and 
other combustion grime are very corrosive. Red lead paint was 
used extensively to combat iron and steel corroison in the early 
part of the 1900's . After about 1950 -60 its use was phased out 
due the toxic natural the pigment in red lead - lead chromate .
