Osaka Municipal Subway 60 series

The Osaka Municipal Subway 60 series is a Japanese city commuter electric multiple unit operated by the Osaka Municipal Transport Bureau from December 1969 to November 2003 on the Sakaisuji Line. 
==History==
The 60 series trains were the first trains introduced on the Sakaisuji Line. A total of eighteen sets were built by Hitachi, Kawasaki, Kisha Seizō and Nippon Sharyo, all in October and November 1969, initially in five-car sets; these were later lengthened to six cars in 1979 and eight cars in 1993, with various cars from various sets inserted into other sets to give eight car sets. By 1992 there were nine sets of eight cars in service. The sets were also designed to through run to Hankyu lines.
The sets were also built without air-conditioning; by 1985 this was an issue on the Hankyu lines, especially during the summer, where commuters would wait for air-conditioned trains and skip the ones without. Demand for an air-conditioned train was high, and with numerous requests the Osaka Municipal Transport Bureau decided to take action and retrofit a number sets with air conditioning units; only five sets (6001 through 6003, 6011 and 6012) received air conditioning units, with the other four remaining non-air-conditioned.
In 1990, the 66 series sets were introduced, intended to improve upon the 60 series, with all sets being air-conditioned from the start. Minor refurbishment work was also carried out but beginning 1992, scrapping began. By 1995 only the five air-conditioned sets remained; these remained in service for some time until 2002, when additional 66 series sets were introduced, whereupon scrapping resumed. The last set, 6002, was retired on 7 November 2003 and scrapped shortly after.
One car, 6014, is preserved. This is a non air-conditioned cab car from set 6014, retired on 18 October 1994. The car is located at Morinomiya Depot, but is not usually open for public viewing. In 2015, the car was restored to its as-built appearance; the car is preserved back-to-back with 50 series car 5085, also restored to its as-built appearance. The 60 series sets are the recipient of the 1970 Laurel Prize as it was regarded as having the most outstanding functional and design features.
==Design==
The 60 series sets feature a conventional front end with two top-mounted headlights.
==Specifications==
Construction is of an aluminum alloy. The sets used resistor-controlled traction systems.
