The Tokyo Underground Railway 1200 series was a Japanese city commuter electric multiple unit operated by the Tokyo Underground Railway and later the Teito Rapid Transit Authority (a predecessor company to what is now Tokyo Metro) from December 1933 to October 1986.
History[]
The 1200 series sets were conceived to account for potential additional service demand following the planned opening of the extension of the Ginza Line from Shimbashi to Shibuya in 1934. A total of 24 cars were produced, manufactured at Kisha Seizō's Tokyo plant and Kawasaki Sharyō's Hyōgo plant, from 1933 to 1934. Intended to be operated in two- or three-car formations, the cars entered service in December 1933.
The 1200 series cars were the last pieces of rolling stock ordered by the Tokyo Underground Railway as they would be acquired by the Teito Rapid Transit Authority in 1941, causing the cars to pass into TRTA (Eidan) ownership. Used during and after World War II, the 1200 series cars were used in conjunction with other rolling stock on the Ginza Line. With TRTA standardizing rolling stock to use 2000 and 1500N series cars in fixed six-car formations, existing early rolling stock such as the 1000 and 100 series were withdrawn from service while others, such as the 1200, 1300 and 1400 series cars were converted into intermediate cars by removing their cabs and associated electrical equipment.
The intermediate car conversions were completed on this series in 1969 and were used as such from then on; their appearance, compared to other cars in a consist, stood out due to their prewar construction methods. Withdrawals commenced in 1984 with the introduction of the 01 series sets and all were withdrawn by 1986; this series had one of the longest service lives of rolling stock on the TRTA.
No 1200 series cars have been preserved.
Specifications[]
The 1200 series's basic design follows that of the 1000 and 1100 series cars; the cars featured smoothed curves and less rivets on their bodies due to advances in welding technology. They were equipped with a driver's cab with a retractable cabin. Compared to the 1000 series cars their numbers were printed on both sides of their cabs to allow for easier viewing when coupling. This feature was continued on all subsequent Ginza Line trains until the 01 series.
The 1200 series notably used domestically manufactured electrical equipment; while the 1000 and 1100 series cars used General Electric electrical equipment, the 1200 series sets used Mitsubishi motors and a main controller which were designed to emulate the characteristics of the GE equipment as closely as possible. This was notably unusual for Mitsubishi as it was affiliated with the Westinghouse Electric Corporation, a rival company to GE.
