context_page_description: The British Rail Class 395 AT300 is a dual-voltage electric multiple unit built by Hitachi for high-speed commuter services on High Speed 1 and elsewhere on the Integrated Kent Franchise. They are all operated by Southeastern.
  The six-car trains were built in Japan and operate at a maximum speed of 140 mph under 25 kV AC overhead electrification on High Speed 1, and 100 mph on 750 V DC third rail supply on conventional lines.
  The use of the high-speed trains as part of the transport infrastructure for the Olympic Park formed part of the original bid for the 2012 Summer Olympics. The service was named the Olympic Javelin Shuttle, which formed the origin of the Javelin nickname. The Olympic services began 28 July 2012.
context_section_description: The 400 Series Mini Shinkansen and Hitachi's A Train design form the basis of the Class 395 design. From the 400 series the class inherits the same 6-car 20 m carriage with doors at one-third and two-thirds along the carriage. Both are designed for operations at high speed on newly built lines as well as at lower speed on conventional legacy lines. Unlike the steel-bodied 400 series, the Class 395 has its carbody (walls, roof, floor) formed from friction stir welded double-walled hollow extruded aluminium body panels, a technology Hitachi considers part of its A-Train train family specification.
  The train consists of six-car units, with all axles on the middle four cars powered. The outer cars are unpowered, but mount the pantographs (giving a formation DPT1+MS1+MS2+MS3+MS4+DPT2.). The bogies are bolsterless, with both powered and unpowered bogies sharing a common design to simplify maintenance. Each 6-car unit can work in multiple with another, creating 12-car trains. Coupling is automated and is designed to take less than 60 seconds.
  For reliability, passenger doors use a relatively simple sliding pneumatic system already in use and development for several decades on Shinkansen trains. The brake system was supplied by Faiveley. Approximately 40% of the train equipment by value was provided by European suppliers.
  There are 340 seats per 6-car train, in standard class [2+2] formation, with 12 additional tip up seats in a wheelchair area. There are two toilets per unit, one of which is equipped for disabled access.
  The trains meet UK Railway Group Standards (RGS), and European Union Technical Specifications for Interoperability (TSI) standards for crashworthiness, and UK or EU standards for structure-load-bearing behaviour, material strength, aerodynamics, noise and fire resistance.
  Each train has a Train Management System (TMS), including equipment monitoring systems, communications, air-conditioning, etc., and equipment-control, including Selective Door Operation (SDO). The SDO system uses GPS and train speed integration to estimate position.
