The Moscow Metro in Moscow, Russia, is the world's most heavily used metro system. It is well known for the ornate design of many of the stations (such as Kievskaya Station, pictured), containing stunningly beautiful examples of socialist realist art. In total, the Moscow Metro has 277.9 km of route length, 12 lines and 171 stations. Although passenger traffic is considerably lower on weekends, on a normal weekday the Metro carries 10.05 million passengers, bringing the average daily passenger traffic per year to 8,745 million passengers per day. Moscow Metro is a state-owned enterprise.

The Wright Flyer (often retrospectively referred to as Flyer I and occasionally Kitty Hawk) was the first powered aircraft designed and built by the Wright brothers. The flight is recognized by the Fédération Aéronautique Internationale, the standard setting and record-keeping body for aeronautics and astronautics, as "the first sustained and controlled heavier-than-air powered flight".

A sailboat or sailing boat is a boat propelled partly or entirely by sails. The term covers a variety of boats, larger than small vessels such as sailboards and smaller than sailing ships, but distinctions in size are not strictly defined and what constitutes a sailing ship, sailboat, or a smaller vessel (such as a sailboard) varies by region and culture. Apart from size, sailboats may be distinguished by hull configuration (monohull, catamaran, trimaran), keel type (full, fin, wing, centerboard etc.), purpose (sport, racing, cruising), number and configuration of masts, and sail plan. Although sailboat terminology has varied across history, many terms now have specific meanings in the context of modern yachting.

The Peugeot 206 is a supermini (subcompact car), manufactured by the French automaker Peugeot since 1998. In 1999, Peugeot Sport unveiled the 206 WRC, and it competed for the first time in that year's World Rally Championship. The car was soon a success, and won the drivers' championship in 2000 in the hands of Marcus Grönholm. In 2002, Grönholm again won the WRC title in his 206 WRC. In addition to the drivers' championships in 2000 and 2002, Peugeot also won the Manufacturers' title three years in a row between 2000 and 2002.

Space Shuttle Columbia (NASA Orbiter Vehicle Designation: OV-102) was the first spaceworthy Space Shuttle in NASA's orbital fleet. Its first mission, STS-1, lasted from April 12 to April 14, 1981. On February 1, 2003, Columbia disintegrated during re-entry over Texas, on its 28th mission, killing all seven crew members.

The Gare Montparnasse is one of the six large terminus train stations of Paris, located in the Montparnasse area, in the XIVe arrondissement. The station is used for the intercity TGV trains to destinations in the west and south-west of France including Tours, Bordeaux, Rennes and Nantes. Additionally, it is served by several suburban and regional services on the Transilien Paris – Montparnasse routes. There is also a metro station, and a high-speed moving sidewalk.

The Eurocopter AS 350 Ecureuil ("Squirrel") and AS 355 Ecureuil 2 are a family of light helicopters originally manufactured by Aérospatiale (now part of Eurocopter Group). The AS 350 (marketed as the AStar in North America) is the single-engined version, while the AS 355 (TwinStar) uses two engines. The EC 130B is a recent adaptation of the AS 350 airframe.

The SS America was an ocean liner built in 1940 for the United States Lines. She carried many names in the 54 years between her construction and her 1994 wrecking, as she served as the SS America (carrying this name three different times during her career), the USS West Point, the SS Australis, the SS Italis, the SS Noga, the SS Alferdoss, and the SS American Star. She served most notably in passenger service as the SS America, and as the Greek-flagged SS Australis for Chandris. In 1941, she carried two Nazi spies from the Duquesne Spy Ring in her crew: Erwin Wilhelm Siegler and Franz Joseph Stigler. Both men were charged by the FBI with espionage and sentenced to 10 years and 16 years' imprisonment, respectively.

The Glacier Express from Zermatt to St. Moritz (or Davos Platz [Summer only]) in Switzerland is one of the great train journeys in the world. It is not an "express" in the sense of being a high-speed train (it isn't) but rather in the sense that it provides a one-seat ride from end to end, even though the train travels over several different railroad lines; reputedly it is the slowest "express" in the world. The trip on the Glacier Express is a 7½ hour railway journey across 291 bridges, through 91 tunnels and across the Oberalp Pass at 2,033 metres in altitude. The entire line is metre gauge, and large portions of it use a rack-and-pinion system both for ascending steep grades and to control the descent of the train on the back side of those grades.

A car accident is a road traffic incident which usually involves at least one road vehicle being in collision with, either another vehicle, another road user, or a stationary roadside object, and which may result in injury or property damage. Phrases used to describe accidents include: auto accident, car crash, car smash, car wreck, fender bender, motor vehicle accident (MVA), personal injury collision (PIC), road accident, road traffic accident (RTA), road traffic collision (RTC), road traffic incident (RTI), smash-up, and traffic collision.

A roundhouse is a building used by railroads for servicing locomotives. Roundhouses are large, circular or semicircular structures that were traditionally located surrounding or adjacent to turntables. The defining feature of the traditional roundhouse was the turntable, which facilitates access when the building is used for repair facilities or for storage of steam locomotives. Early steam locomotives normally travelled forwards only; although reverse operations capabilities were soon built into locomotive mechanisms, the controls were normally optimized for forward travel, and the locomotives often could not operate as well in reverse. Some passenger cars, such as observation cars, were also designed as late as the 1960s for operations in a particular direction. A turntable allowed a locomotive or other rolling stock to be turned around for the return journey.

The Boeing (formerly McDonnell Douglas) C-17 Globemaster III is a large American airlifter manufactured by Boeing Integrated Defense Systems, and operated by the United States Air Force, British Royal Air Force, the Royal Australian Air Force, and the Canadian Forces Air Command. NATO and Qatar will also acquire the airlifter. The C-17 Globemaster III is capable of rapid strategic delivery of troops and all types of cargo to main operating bases or directly to forward bases in the deployment area. It is also capable of performing tactical airlift, medical evacuation and airdrop missions. The C-17 takes its name from two previous United States cargo aircraft, the C-74 Globemaster and the C-124 Globemaster II.
