The MS Multi-section, a series of New York City Subway cars, was built in prototype form in 1934 with production models built in 1936. They were called "Multis" for short.
The MS was an articulated car made up of five sections. Their average length was 170 ft (52 m), making them the longest articulated units ever used in the history of the BMT. The first two pilot cars, numbered 7003 and 7029, were delivered in 1934 by the Budd Company and Pullman Company. The Pullman version was known as the Green Hornet, while Budd's was called the Zephyr, both names being unofficial. The Green Hornet (and the 25 production cars) had two double-leaf doors on each section (10 doors per unit), while the Zephyr had four single-leaf doors on each section (20 doors per unit). These cars were in production at the same time as the Union Pacific M-10000 and the Budd Pioneer Zephyr for the CB&Q. Testing of these cars proved successful and the BMT ordered a further 25 cars, 15 from Pullman and 10 from St. Louis Car Co.
The two units were initially tested on the Fulton St. el for comparison, and when the tests were concluded they were relegated to Franklin Ave. Shuttle service, almost never appearing in through service to Brighton Beach or Coney Island except occasionally for put-ins (out-of-service trains re-inserted in revenue service) or layups (out-of-service trains stored on unused yard or express tracks).
The Green Hornet had undergone some slight modifications, and the BMT management hoped to eventually run it in consists with the Pullman-Standard built Multi units. However, with the onset of World War II, the Green Hornet was scrapped in 1942 for its valuable aluminum body. The unit had been plagued by master controller problems and was only in service for three years before it was withdrawn after maintenance revealed two cracked trucks. The Zephyr had a much better service record and remained in service on the Franklin Avenue Shuttle until it was retired in 1954. The unit was scrapped in 1959.
