A LITTLE PAINT HIDES A LOT OF DIRT. Where Worlds Collide is not impressed with the latest image makeover on the Midland Main Line, and asks, "I notice American railroads don't feel they have to rebrand themselves every couple of years; doesn't Union Pacific still stick to the same colour scheme they used in the 1950s?" The Armour yellow dates at least to the M-10000 streamliner in 1934, and the nose wings are from about the same time. The red lettering is a bit newer. The shield dates to the early 1900s. Many railroads did make over their images in the 1950s and 1960s, usually not successfully. The new large systems have gone back to classic colors of their predecessor companies. The red and silver of Burlington Northern Santa Fe is another streamliner design from the mid-1930s, and the orange and green borrow from the Great Northern's 1947 redesign. Canadian Pacific have brought back the shield and the beaver. Norfolk and Western and Southern both painted their freight diesels black. The South Shore Line has been traction orange and maroon since the 1920s.
