Rail transport is a means of conveyance of passengers and goods by way of wheeled vehicles running on rail tracks. In contrast to road transport, where vehicles merely run on a prepared surface, rail vehicles are also directionally guided by the tracks on which they run. Track usually consists of steel rails installed on sleepers/ties and ballast, on which the rolling stock, usually fitted with metal wheels, moves. However, other variations are also possible, such as slab track where the rails are fastened to a concrete foundation resting on a prepared subsurface.
Rolling stock in railway transport systems generally has lower frictional resistance when compared with highway vehicles, and the passenger and freight cars (carriages and wagons) can be coupled into longer trains. The operation is carried out by a railway company, providing transport between train stations or freight customer facilities. Power is provided by locomotives which either draw electrical power from a railway electrification system or produce their own power, usually by diesel engines. Most tracks are accompanied by a signalling system. Railways are a safe land transport system when compared to other forms of transport. Railway transport is capable of high levels of passenger and cargo utilization and energy efficiency, but is often less flexible and more capital-intensive than highway transport is, when lower traffic levels are considered.
Sidney K. "Sid" Meier (born February 24, 1954) is a Canadian-American programmer and designer of several popular strategy video games and simulation video games, most notably Civilization. Meier co-founded MicroProse in 1982 and is a Director of Creative Development for computer game developer Firaxis Games, which he co-founded with Jeff Briggs and Brian Reynolds in 1996. He has won several prestigious accolades for his contributions to the computer games industry.
Sid Meier was born in Sarnia, Ontario, Canada. He graduated from the University of Michigan.
Meier founded MicroProse together with Bill Stealey in 1982. MicroProse initially developed flight simulator video games, such as Silent Service and F-19 Stealth Fighter. In 1987, the company released Sid Meier's Pirates!, which also began a trend of placing Meier's name in the titles of his games. Meier later explained that the inclusion of his name was because of the dramatic departure in the design of Pirates! compared to the company's earlier games. Stealey decided that it would improve the company's branding, believing that it would make those who purchased the flight simulators more likely to play Pirates!. After the release of F-19 Stealth Fighter, Meier decided to focus on developing strategy games. He later said, "Everything I thought was cool about a flight simulator had gone into that game." Inspired by SimCity and Empire!, Meier created Railroad Tycoon and later the game series for which he is most widely recognized, Civilization, although he designed only the first installment. Meier eventually left MicroProse and in 1996 founded Firaxis Games along with veteran designer and gaming executive Jeff Briggs. Today Firaxis makes strategy games, many of which are follow-ups to Meier titles, such as Civilization V and Pirates!. In 1996 he was awarded US Patent 5,496,962 for a "System for Real-Time Music Composition and Synthesis" used in a product called "CPU Bach".
