Tâi-lô. Tâi-uân Ko-thih. Taiwan High Speed Rail ( THSR) is the high-speed railway of Taiwan consisting of one line that runs approximately 350 km (217 mi) along the west coast, from the capital Taipei to the southern city of Kaohsiung. With construction and operations managed by a private company, Taiwan High Speed Rail Corporation (THSRC ...
High-speed rail (HSR) is a type of rail transport network utilizing trains that run significantly faster than those of traditional rail, using an integrated system of specialized rolling stock and dedicated tracks. While there is no single standard that applies worldwide, lines built to handle speeds above 250 km/h (155 mph) or upgraded lines ...
Egypt has no operational high-speed rail links, but a project was launched in 2018 to construct three such lines with a total length of about 2,000 kilometres (1,200 mi). The first line links the cities of Ain Sukhna and Marsa Matrouh, the second connects the cities of Sixth of October and Abu Simbel, and the third connects the city of Qena ...
Projected HSR network in China by 2020 and travel time by rail from Beijing to provincial capitals. China's high-speed railway network is by far the longest in the world.As of December 2022, it extends to 31 of the country's 33 provincial-level administrative divisions and exceeds 40,000 km (25,000 mi) in total length, accounting for about two-thirds of the world's high-speed rail tracks in ...
The earliest high-speed rail line built in Europe was the Italian " Direttissima ", the Florence–Rome high-speed railway 254 km (158 mi) in 1977. The top speed on the line was 250 km/h (160 mph), giving an end-to-end journey time of about 90 minutes with an average speed of 200 km/h (120 mph). This line used a 3 kV DC supply.
The high-speed rail (HSR) network in the People's Republic of China (PRC) is the world's longest and most extensively used – with a total length of 45,000 kilometres (28,000 mi) by the end of 2023. [1] [2] [3] The HSR network encompasses newly built rail lines with a design speed of 200–380 km/h (120–240 mph). [4]
The synthesis commences with cyclopropanation of 1,1-bis(chloromethyl)ethylene, according to the following scheme: Scheme 1. Synthesis of [1.1.1]propellane. Synthesis begins with conversion of the 1,3-di-carboxylic acid of bicyclo[1.1.1]pentane 1 in a Hunsdiecker reaction to the corresponding dibromide 2 followed by a coupling reaction with n ...
