CSL/CTA streetcar 1497 was renumbered as AA85 for work service as a salt spreader, the configuration we see it in here in this 1950s photo. It was scrapped on September 27, 1956. This was known as a "Bowling Alley" car. Don's Rail Photos: "1497 was built by CUTCo in 1900 as CUT 4546. It was rebuilt as 1497 in 1911 and became CSL 1497 in 1914. It was rebuilt as salt car and renumbered AA85 on April 15, 1948."
