Electric Multiple Units Of The United States
Electricity is the set of physical phenomena associated with the presence and motion of matter possessing an electric charge. Electricity is related to magnetism, both being part of the phenomenon of electromagnetism, as described by Maxwell's equations. Common phenomena are related to electricity, including lightning, static electricity, electric heating, electric discharges and many others. The presence of either a positive or negative electric charge produces an electric field. The motion of electric charges is an electric current and produces a magnetic field. In most applications, Coulomb's law determines the force acting on an electric charge. Electric potential is the Work (physics), work done to move an electric charge from one point to another within an electric field, typically measured in volts. Electricity plays a central role in many modern technologies, serving in electric power where electric current is used to energise equipment, and in electronics dealing w ...

Twin Unit
A twin unit, twinset, or double unit is a set of two railroad Railway car, cars or locomotives which are permanently coupled and treated as if they were a single unit. A twinset of cars or coaches can also be called a twin car. In US passenger railroad parlance, twin units are also known as married pairs. On passenger railroads, light rail, and monorail services, married pairs may have machinery necessary for full operation of the cars split between them. Items that are typically shared include transformers, motor controllers, dynamic braking grids, cabs, current collectors, batteries, and air compressors. This provides significant savings in both cost of equipment and weight, which increases performance and decreases energy consumption. The Operating cost, cost of operating such a pair may be slightly higher when the extra car in such a pair is not needed to meet level-of-service demands at a particular time.

Gangway Connection
A gangway connection or corridor connection is a flexible connector fitted to the end of a railway coach, enabling passengers to move between coaches without danger of falling from the train. Origins: Coaches in British and American railways The London and North Western Railway (LNWR) was the first British railway to provide passengers with the means to move from one coach to another while the train was in motion. In 1869 the LNWR built a pair of saloons for the use of Queen Victoria; these had six-wheel underframes (the bogie coach did not appear in Britain until 1872), and the gangway was fitted to only one end of each coach. The Queen preferred to wait until the train had stopped before using the gangway. In 1887, George M. Pullman introduced his patented vestibule cars. Older railroad cars had open platforms at their ends, which were used both for joining and leaving the train, but could also be used to step from one car to the next. This practice was dangerous, and so Pu ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
