Sapporo Streetcar 570 series

The Sapporo Streetcar 570 series was a Japanese streetcar type operated by the Sapporo Municipal Transport Bureau on the Sapporo Streetcar network from June 1954 to December 1971.
==History==
The 570 series cars was a series of streetcars manufactured for the Sapporo Streetcar network. A total of ten cars were manufactured numbered 571 through 580, with 571 through 574 manufactured by Kisha Seizō in June 1954, 575 manufactured by Kisha Seizō in August 1954 and 576 through 580 manufactured by Naniwa Kōki in June 1955.
Operation began in June 1954. 571 was involved in a collision with a truck in 1964; it was immediately dismantled and cannibalized for parts. The remaining 570 series cars were dismantled in 1965, with the exception of 575; these cars would be rebuilt into the A850 series connected streetcars using new electronics. 575 remained in service until December 1971. No 570 series cars have been preserved.
==Design==
The 570 series cars featured a boxy design. Initially painted in dark green with lighter green accents, the cars were later repainted in the Sapporo Municipal Transport Bureau's corporate colors of a tan body with green accents.
571 through 575 featured a top-mounted headlight; 576 through 580 had the headlight moved to the center of the cab when the top-mounted headlight was found to provide insufficient illumination.
==Specifications==
Construction of the cars was of steel. The cars used a nose suspension drive system and rode on various types of Sumitomo bogies.
575 featured numerous experimental technologies for a streetcar, such as electromagnetic drum brakes, soundproof gears and a different control system; when 575 was found to be difficult to control and brake it was modified to feature the same control system and features as all other 570 series cars.
