Universal Design
Universal design is the design of buildings, products or environments to make them accessible to people, regardless of age, disability or other factors. It addresses common barriers to participation by creating things that can be used by the maximum number of people possible. Curb cuts or sidewalk ramps, which are essential for people in wheelchairs but also used by all, are a common example of universal design. The term ''universal design'' was coined by the architect Ronald Mace to describe the concept of designing all products and the built environment to be aesthetic and usable to the greatest extent possible by everyone, regardless of their age, ability, or status in life. However, due to some people having unusual or conflicting access needs, such as a person with low vision needing bright light and a person with photophobia needing dim light, universal design does not address absolutely every need for every person in every situation. Universal design emerged from sli ...

Tōkaidō Main Line
The is a major Japanese railway line of the Japan Railways Group (JR Group) network, connecting and stations. It is long, not counting its many freight feeder lines around the major cities. The high-speed Tōkaidō Shinkansen largely parallels the line. The term "Tōkaidō Main Line" is largely a holdover from pre-Shinkansen days; now various portions of the line have different names which are officially used by JR East, JR Central, and JR West. Today, the only daily passenger train that operate over the entire length of the line is the combined overnight-train Sunrise Izumo - Sunrise Seto. During the day longer intercity trips require several transfers along the way. The Tokaido Main Line is owned and operated by three JR companies: * East Japan Railway Company (JR East) ( - ) Tōkaidō Line * Central Japan Railway Company (JR Central) ( - ) Tōkaidō Line * West Japan Railway Company (JR West) ( - ) Biwako Line, JR Kyoto Line, JR Kobe Line Basic data *Total distance: (i ...

E231 Series
The is an electric multiple unit (EMU) train type used for commuter and outer-suburban services operated by East Japan Railway Company (JR East) in Japan since 2000. Design Trains were manufactured by Tokyu Car Corporation, Kawasaki Heavy Industries and also at JR East's factory at Niitsu in Niigata Prefecture. The type evolved from the earlier 209 series and E217 series EMUs, with the main visible difference being wider bodies (2,950 mm compared to the 2,800 mm for earlier commuter trains), and the prototype train built in 1998 for trials on the Chūō–Sōbu Line was actually classified 209-950 series, later becoming E231-900 series. Full-production E231-0 series trains were subsequently introduced on the Chūō–Sōbu Line (10-car sets) and Jōban Line (10+5-car sets). Other variants include the 11-car E231-500 series for the Yamanote Line, and the E231-800 series with 2,800 mm wide bodies and end doors for use on Tokyo Metro Tozai Line inter-running serv ...

Ueno Station
is a major railway station in Tokyo's Taitō ward. It is the station used to reach the Ueno district and Ueno Park—which contains Tokyo National Museum, The National Museum of Western Art, Ueno Zoo, Tokyo University of the Arts and other famous cultural facilities. A major commuter hub, it is also the traditional terminus for long-distance trains from northern Japan, although with the extension of the Shinkansen lines to Tokyo Station this role has diminished in recent years. A similar extension of conventional lines extended Takasaki Line, Utsunomiya Line and Joban Line services to Tokyo Station via the Ueno-Tokyo Line in March 2015, using existing little-used tracks and a new viaduct; the Ueno-Tokyo Line connects these lines with the Tokaido Main Line, allowing through services to Shinagawa, Yokohama, Odawara and Atami stations. Ueno Station is close to Keisei Ueno Station, the Tokyo terminus of the Keisei Main Line to Narita Airport Station. Lines This station is serv ...

Electric Multiple Unit
An electric multiple unit or EMU is a multiple-unit train consisting of self-propelled carriages using electricity as the motive power. An EMU requires no separate locomotive, as electric traction motors are incorporated within one or a number of the carriages. An EMU is usually formed of two or more semi-permanently coupled carriages, but electrically powered single-unit railcars are also generally classed as EMUs. The great majority of EMUs are passenger trains, but versions also exist for carrying mail. EMUs are popular on commuter and suburban rail networks around the world due to their fast acceleration and pollution-free operation. Being quieter than diesel multiple units (DMUs) and locomotive-hauled trains, EMUs can operate later at night and more frequently without disturbing nearby residents. In addition, tunnel design for EMU trains is simpler as no provision is needed for exhausting fumes, although retrofitting existing limited-clearance tunnels to accommodate the ...

Automatic Train Stop
Automatic train stop or ATS is a system on a train that automatically stops a train if certain situations occur (unresponsive train operator, earthquake, disconnected rail, train running over a stop signal, etc.) to prevent accidents. In some scenarios it functions as a type of dead man's switch. Automatic train stop differs from the concept of Automatic Train Control in that ATS usually does not feature an onboard speed control mechanism. Overview Mechanical systems The invention of the fail-safe railway air brake provided an external means for stopping a train via a physical object opening a valve on the brake line to the atmosphere. Eventually known as ''train stops'' or ''trip stops'', the first mechanical ATS system was installed in France in 1878 with some railroads in Russia following suit using a similar system in 1880. In 1901 Union Switch and Signal Company developed the first North American automatic train stop system for the Boston Elevated Railway. This system was so ...
