Rajdhani Express

The Rajdhani Express is a series of express passenger train services in India operated by Indian Railways connecting New Delhi with other important destinations (mostly capital cities of other states). Rajdhani means "The Capital" in many Indian languages. The Rajdhanis are among the fastest trains in India along with Shatabdi Express and Duronto Express and get the highest priority on the Indian railway network.

History

Rajdhani Express was introduced in 1969, for providing fast connections (up to 140 km/h or 87 mph, speed variation depending upon the particular track section) from New Delhi to the capital cities of various states in India. The first Rajdhani Express left New Delhi station for Howrah station to cover a distance of 1,445 km in 17 hours 20 mins.

About

Rajdhani express get highest priority on the Indian railway network. They are fully air-conditioned. Passengers are served complimentary meals during the journey. Depending on the duration and timings of the journey, these could include morning tea, breakfast, lunch, high tea and dinner. All Rajdhani Express trains offer three classes of accommodation: AC First Class with 2-berth and 4-berth lockable bedrooms, AC 2-tier with open berths (bays of 4 berths + 2 berths on the other side of the corridor) with curtains for privacy, and AC 3-tier (bays of 6 berths + 2 berths on the side) without curtains. Currently there are 22 pairs of trains, connecting New Delhi to important cities across the country. These trains have fewer stops than other express trains and halt only at prominent stations. The Indian Railways has also introduced free wi-fi facility in Rajdhani Express trains.

Space station

A space station, also known as an orbital station or an orbital space station, is a spacecraft capable of supporting a crew, which is designed to remain in space (most commonly as an artificial satellite in low Earth orbit) for an extended period of time and for other spacecraft to dock. A space station is distinguished from other spacecraft used for human spaceflight by lack of major propulsion or landing systems. Instead, other vehicles transport people and cargo to and from the station. As of September 2014 two space stations are in orbit: the International Space Station, which is permanently manned, and China's Tiangong-1 (which successfully launched on September 29, 2011), which is unmanned most of the time. Previous stations include the Almaz and Salyut series, Skylab and most recently Mir.

Today's space stations are research platforms, used to study the effects of long-term space flight on the human body as well as to provide platforms for greater number and length of scientific studies than available on other space vehicles. Each crew member staying aboard the station for weeks or months, but rarely more than a year. Most of the time crew remain at station but its not necessary that crew should have to be stay at station. Since the ill-fated flight of Soyuz 11 to Salyut 1, all manned spaceflight duration records have been set aboard space stations. The duration record for a single spaceflight is 437.7 days, set by Valeriy Polyakov aboard Mir from 1994 to 1995. As of 2013, three astronauts have completed single missions of over a year, all aboard Mir.

International Space Station

The International Space Station (ISS) is a space station, or a habitable artificial satellite, in low Earth orbit. Its first component launched into orbit in 1998, and the ISS is now the largest artificial body in orbit and can often be seen with the naked eye from Earth. The ISS consists of pressurised modules, external trusses, solar arrays, and other components. ISS components have been launched by Russian Proton and Soyuz rockets as well as American Space Shuttles.

The ISS serves as a microgravity and space environment research laboratory in which crew members conduct experiments in biology, human biology, physics, astronomy, meteorology, and other fields. The station is suited for the testing of spacecraft systems and equipment required for missions to the Moon and Mars. The ISS maintains an orbit with an altitude of between 330 and 435 km (205 and 270 mi) by means of reboost manoeuvres using the engines of the Zvezda module or visiting spacecraft. It completes 15.54 orbits per day.

Mumbai Rajdhani Express

The 12951/12952 Mumbai Rajdhani Express is a super fast express train of Rajdhani class belonging to Indian Railways that runs between Mumbai and Delhi in India. It was introduced on 17 May 1972 between the then Bombay Central and New Delhi. Since the time of its introduction, the train is so much popular that before the introduction of reservation against current availability, its reservation chart was prepared only 15 minutes before the scheduled departure. It is a daily service. It operates as train number 12951 from Mumbai Central to New Delhi and as train number 12952 in the reverse direction.

Coaches

The Mumbai Rajdhani generally has one AC 1st Class coach, five AC 2 tier class coaches, two pantry cars, two luggage cum generator coaches & up to eleven AC 3 tier coaches taking the total up to 21 coaches. Since its inception, the Mumbai Rajdhani ran with 16 coaches. However, the conventional rakes were replaced by Linke-Hofmann Busch (LHB) coaches for this train in 2004 and the number of coaches was also increased to 19 including the pantry cars.The number of coaches again was increased to 21 by the Western Railways to accommodate more passengers in June 2012.
