This Seabord Coast Line streamlined diesel train #4900 was built in 1936 by St. Louis Car Company, and was an obvious influence on the design of the North Shore Line Electroliners, built five years later, The 4900 was scrapped in 1971 after Amtrak took over intercity passenger rail service. It is shown here in August 1969 and was originally Seaboard Air Line 2028. Like the Electroliners, it was one of a pair. (Wien-Criss Archive)
