The Electroliners are a pair of streamlined interurban trainsets built by the St. Louis Car Company in 1941. Initially numbered 801–802 and 803–804, they were operated by the Chicago North Shore and Milwaukee Railroad from 1941 to 1963, followed by the Philadelphia Suburban Transportation Company (later SEPTA) from 1964 to 1978. Since their retirement, both trainsets have been preserved in railway museums.
