Background and overview
JR Central developed 313-2600 series suburban DC electric multiple unit (EMU) trains to displace 113 series used on ordinary services in Shizuoka area in 2006. 313-2600 series can be operated coupled with 211 series EMU together, and feature mixed regenerative-dynamic braking. Ten 3-car sets consisting of 2 powered vehicles and 1 trailer vehicle were delivered.

Car body
They have 2930mm wide body, incorporating light weight stainless construction. Their pier panels (strength members) are also gotten rid of to match various seating arrangements. Their bodies are unpainted and have the orange waistline and headline bands running through the length of each car below and above the windows. Their gangwayed cab end section painted in white is constructed by steel. Anti-fall plates between vehicles are also introduced excepting the cab end. They are equipped with three 1300mm wide double-leaf automatic sliding doors on each side of the vehicles, which can be operated manually by pushing the button fitted beside the door, on each side of the vehicles. Horizontal band of 4 set fixed windows having 930mm height are fitted between the doors and hopper windows are at the end of their body. Double-glazing UV cut glass is employed for all windows to improve noise insulation property and to prevent dew condensation. Full-colour LED destination indicators are fitted on the side of their body and a full-colour LED destination indicator and a full-colour LED train-type indicator are fitted at the front of end vehicles. Two air conditioners, C-AU715, rated at 21,000kcal/h/unit and employing R407C refrigerant, and no ventilators are fitted on their roof. Loudspeakers, providing guidance broadcast for passengers waiting at a station, are fitted on their roof. End cars are equipped with the automatic jumper coupler to ease rush-up operations.

Bogies
Motored bogies are C-DT63B and trailer bogies are C-TR251A, featuring bolster-less secondary air suspension, corn-shaped multilayered rubber spring journal supporting system, and the single link traction device. The yaw dampers are adopted to ensure smooth ride characteristics even at 120km/h. Twin Disc (TD) flexible joint employing deflecting plates made of carbon-fiber reinforced plastic (CFRP) is applied for power transmission device. Motored bogies employ the single tread brake device adopting automatic gap-adjusting unit, and trailer bogies employ both the double disk brake device and the wheel tread cleaning device.

Traction unit and ancillary equipments
Class moha313-2600 vehicles are equipped with both a motored bogie and a trailer bogie to make same quantity of powered axles and trailer axles in a 3-car set. Thus, powered end vehicles, class kumoha313-2600, are equipped with a 3-step Variable-frequency drive (VFD) traction system, C-CS37A, featuring Insulated Gate Bipolar Transistor (IGBT) and controlling four asynchronous traction motors, C-MT66C, with a power output of 185kW on truck basis. This traction system is integrated with the auxiliary power supply unit with a power output of 150kVA. In case of the auxiliary power supply unit failure, one VFD unit for traction motor drive can switch to supply electricity as the backup auxiliary power supply unit. On the other hand, powered intermediate vehicles, class moha313-2500, are equipped with a traction system, C-CS38A, controlling two traction motors. Powered end vehicles are also equipped with a single arm type current pickup, C-PS27B, on their roof. Trailer end vehicles and intermediate vehicles are equipped with a motor driven air compressor, C-C1000ML, under their floor. 313-2600 series feature the electric commanding brake with mixed regenerative-dynamic braking against low possibility of regeneration and holding brake, featuring brake control of trailer priority and electric braking to zero speed.

Accommodation
Passenger accommodation consists of longitudinal bench seating throughout, with an individual seat width of 460 mm per person, compared to 440 mm for the earlier 211-5000 series. Handrails are fitted at the both end and middle of seats. Their lighting cover differs from former 313 series in being made of the glass fibre. The air conditioning duct is fitted above the ceiling in order to improve interior design and the outlets of cool air are slit shape. Straps were fitted throughout their body. A LED display for providing passenger information, and a door chime are fitted above the door header of the sliding doors. Trailer end cars, class kuha312-2300, are equipped with a universal access style toilet employing an automatic wide sliding door, which can be operated manually by pushing the buttons, and a chemical holding tank.

Operations
313-2600 series have been used on the ordinary services of Tokaido, Gotemba, and Minobu lines from November, 2006.
313-3000 series are now used on the rural services of Gotemba, Minobu, Iida, and Tokaido lines.
