High-speed rail

High-speed rail is a type of rail transport that operates significantly faster than traditional rail traffic, using an integrated system of specialized rolling stock and dedicated tracks. While there is no single standard that applies worldwide, new lines in excess of 250 km/h and existing lines in excess of 200 km/h are widely considered to be high-speed, with some extending the definition to include much lower speeds (e.g. 160 km/h) in areas for which these speeds still represent significant improvements. The first such system began operations in Japan in 1964 and was widely known as the bullet train. High-speed trains normally operate on standard gauge tracks of continuously welded rail on grade-separated right-of-way that incorporates a large turning radius in its design.

Many countries have developed high-speed rail to connect major cities, including Austria, Belgium, China, France, Germany, Italy, Japan, Poland, Portugal, Russia, South Korea, Spain, Sweden, Taiwan, Turkey, United Kingdom, United States and Uzbekistan. Only in Europe does HSR cross international borders. China has 19,000 km of HSR as of December 2015, accounting for two thirds of the world's total.

Business class

Business class is a travel class available on many commercial airlines and rail lines, known by brand names which vary by airline or rail company. In the airline industry, it was originally intended as an intermediate level of service between economy class and first class, but many airlines now offer business class as the highest level of service, having eliminated first class seating. Business class is distinguished from other travel classes by the quality of seating, food, drinks, ground service and other amenities. Full business class is usually denoted 'J' or 'C' with schedule flexibility, but can be many other letters depending on circumstances.

Airlines

History

Airlines began separating full-fare and discounted economy class passengers in the late 1970s. In 1976, KLM introduced a Full Fare Facilities (FFF) service for its full fare economy class passengers, which allowed them to sit at the front of the economy cabin immediately behind first class, and this concept was quickly copied by several other airlines including Air Canada. Both United Airlines and Trans World Airlines experimented with a similar three-class concept in 1978, but abandoned it due to negative reactions from discount economy class travelers who felt that amenities were being taken away from them. United also cited the difficulty of tracking which passengers should be seated in which section of the economy cabin on connecting flights.American Airlines also began separating full-fare economy passengers from discounted economy passengers in 1978, and offered open middle seats for full-fare passengers.

China

China, officially the People's Republic of China (PRC), is a sovereign state in East Asia. It is the world's most populous country, with a population of over 1.35 billion. The PRC is a one-party state governed by the Communist Party, with its seat of government in the capital city of Beijing. It exercises jurisdiction over 22 provinces; five autonomous regions; four direct-controlled municipalities (Beijing, Tianjin, Shanghai and Chongqing); two mostly self-governing special administrative regions (Hong Kong and Macau); and claims sovereignty over Taiwan.

Covering approximately 9.6 million square kilometers, China is the world's second-largest country by land area, and either the third or fourth-largest by total area, depending on the method of measurement. China's landscape is vast and diverse, ranging from forest steppes and the Gobi and Taklamakan deserts in the arid north to subtropical forests in the wetter south. The Himalaya, Karakoram, Pamir and Tian Shan mountain ranges separate China from South and Central Asia. The Yangtze and Yellow Rivers, the third- and sixth-longest in the world, run from the Tibetan Plateau to the densely populated eastern seaboard. China's coastline along the Pacific Ocean is 14,500 kilometres (9,000 mi) long, and is bounded by the Bohai, Yellow, East and South China Seas.

First class

First class (or 1st class, Firstclass) generally implies a high level of service, importance or quality. Specific uses of the term include:

Arts and Entertainment

Comics

Film

Music

Television

Computing

InterCity 125

The InterCity 125 was the brand name of British Rail's High Speed Train (HST) fleet, which was built from 1975 to 1982 and was introduced in 1976. The InterCity 125 train is made up of two Class 43 power cars, one at each end of a fixed formation of Mark 3 carriages (the number of carriages varies by operator). The train operates at speeds of up to 125 mph (201 km/h) in regular service, and has an absolute maximum speed of 148 mph (238 km/h), making it the fastest diesel-powered train in the world, a record it has held from its introduction to the present day. Initially the sets were classified as Classes 253 and 254. A variant of the power cars operates in Australia as part of the XPT.

After four decades, most of the HST fleet is still in front-line revenue service under privatisation, and while the InterCity 125 brand name is rarely mentioned officially by the private train-operating companies (TOCs), the InterCity 125 still forms the backbone of intercity services on several British main lines. Almost all sets are expected to be replaced by 2018 by the Intercity Express Programme. Under early plans for that programme, some HSTs were due to continue in use on London to Devon/Cornwall services, where there are no plans to electrify the lines. However, in March 2015 it was announced that the remainder of the Great Western fleet would be replaced with bi-mode Intercity Express sets, equipped with the required powerplants and fuel tanks to tackle the distances and inclines of Westcountry services.
