The Osaka Municipal Subway 70 series (大阪市交通局70系) is a rapid transit electric multiple unit (EMU) train type operated by Osaka Municipal Subway on the Nagahori Tsurumi-ryokuchi Line in Japan.[1]
The 70 series was among the earliest trains in Japan to use linear motors, and is capable of driverless operation.
Refurbishment[edit]
All 25 70 series trains are scheduled to undergo major refurbishment, with set 13 the first refurbished set to re-enter service on March 4, 2011.[citation needed] The refurbishment will include the fitting of new linear motor traction systems, a new 3-colour LED display system above passenger doors, new LCD passenger information monitors, lower hand grips, a yellow line printed on passenger doors and new train car number indicators on the exterior similar to those seen on the 30000 series and the refurbished 25 series trains.
