          6. Second section of the Daylight as it ran circa 1940. From left
        
        
          to right: a pair of lightweight chair cars in dark olive, Daylight-
        
        
          painted chair car and coffee shop car, and a two-tone gray
        
        
          heavyweight dining car.
        
        
          latest high-fashion styling, and the entire train was air condi-
        
        
          tioned, a very new feature at the time.
        
        
          While most streamliners used internal combustion engines,
        
        
          the SP contracted Lima Locomotive Works to build GS-2
        
        
          class steam engines with a 4-8-4 wheel arrangement. These
        
        
          were mechanically similar to the SP’s earlier 4-8-4s, but the
        
        
          new engines had functional sheet metal skyline casings that
        
        
          deflected smoke away from the cab in tunnels. There was also
        
        
          decorative side skirting and a nose cone. The engines were fin-
        
        
          ished in brilliant scarlet and orange to match the new train.
