These were the first heavy interurbans purchased by the company from St. Louis Car in 1903. Previously double truck city cars and cars from the original MRK were used. They were unusual having a rather flat two window end and deck roofs. They were always 600 volt cars, and after 3300 volt current was placed in use west of St. Martins and Waukesha Beach, they were confined to MRK and South Milwaukee use. In the 1920s, rebuilt 1100s replaced them on the MRK line and rebuilt 600s took over South Milwaukee. Fourteen were converted to freight motors and several remained in use on the Carrollville branch of the South Milwaukee line. The last were scrapped after that service was abandoned in 1934.

1004 was rebuilt as a South Milwaukee shuttle car in 1920 and retired on June 30, 1936.

1005 was rebuilt as a South Milwaukee shuttle car in 1920 and retired on June 30, 1936, but apparently was not scrapped for several years.

1011 was rebuilt in 1923 as express trailer M21. In 1925 the trucks were replaced with St. Louis 23M trucks from 1109. It was retired in April 1941 and scrapped.

1025 was retired on June 30, 1936.
