The Eidan 1400 series was a Japanese city commuter electric multiple unit operated by the Teito Rapid Transit Authority (a predecessor company to what is now Tokyo Metro) from June 1954 to December 1985.
History[]
The 1400 series sets were conceived as a prototype train used to test the equipment intended to be fitted on the upcoming 300 series cars to be used on the Marunouchi Line. Two caes were produced, both at Kisha Seizō's Tokyo plant, in June 1954. The cars entered service the same month; their numbering started from 1470, following on from the last 1300 series car being numbered 1369. The trains used the latest electrical equipment imported from the United States, manufactured by the Westinghouse Electric Corporation. After the Marunouchi Line opened in January 1954, the 1400 series' electrical equipment was transferred to the 500 series cars, with the cars then fitted with the same electrical equipment used on the 1300 series.
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and 1500N series cars in fixed six-car formations, existing early rolling stock such as the 1000 and 100 series were withdrawn from service while others, such as the 1200, 1300 and 1400 series cars were converted into intermediate cars by removing their cabs and associated electrical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 postwar construction methods. Unlike other cars, the 1400 series cars retained their motors. With the introduction of the 01 series sets, both cars were withdrawn in December 1985 and scrapped.
No 1400 series cars have been preserved.
Specifications[]
The 1400 series's basic design follows that of the 1000 and 1200 series cars; it featured a slightly more modern appearance due to the lack of sills or headers. The cars featured a distinctive vent on the roof, a feature of the train's Mitsubishi Fandelier air distribution system, it being the first train to have such a feature, although it was later replaced with standard oscillating fans.
The 1400 series cars were the first trains in Japan to use the Westinghouse-Natal drive, commonly known as a "WN drive" in Japanese railway parlance; this driveshaft system was developed by Westinghouse in conjunction with Natal, a subsidiary of Westinghouse. This drive system would later be adopted en masse by numerous pieces of rolling stock around Japan, including the highly influential 0 Series Shinkansen sets.
