The engineer of the Grand Trunk Western Jackson turn (from Pontiac to Jackson and back) takes a cigarette break at Jackson Yard.  This is GTW #1950, a 1,000 hp. Alco RS-1, one of the first road switchers introduced in the 1940's.  The controls on the RS-1 were simpler than found on $2 million locomotives in 2008.  This photo was taken in 1964..
