Environmental design is an emerging topic in railroad technology. From the 1980s to 2009, fuel efficiency in diesel locomotives in the USA has increased 85%, [1] allowing these trains to go farther and move more freight while using less fuel. New low-impact electric and hybrid trains reduce overall carbon emissions.
Steam locomotives constructed in the 21st century fall into two broad categories: those that use advanced steam technology to be commercially competitive with diesels; and those built to more traditional designs for hauling tourist trains. Even locomotives in the second case likely use some modern methods and materials.
The first steam locomotive in South Korea (Korea at the time) was the Moga (Mogul) 2-6-0, which first ran on 9 September 1899 on the Gyeong-In Line. Other South Korean steam locomotive classes include the Sata, Pureo, Ame, Sig, Mika (USRA Heavy Mikado), Pasi (USRA Light Pacific), Hyeogi (Narrow gauge), Class 901, Mateo, Sori and Tou. Used until ...
A steam locomotive is a locomotive that provides the force to move itself and other vehicles by means of the expansion of steam. [1]: 80 It is fuelled by burning combustible material (usually coal, oil or, rarely, wood) to heat water in the locomotive's boiler to the point where it becomes gaseous and its volume increases 1,700 times.
The LNER Class V2 2-6-2 steam locomotive, number 4771 Green Arrow was built in June 1936 for the London and North Eastern Railway (LNER) at Doncaster Works to a design of Nigel Gresley. The first-built and sole surviving member of its class, it was designed for hauling express freight and passenger trains [2] and named after an express freight ...
It used a steam locomotive built by George Stephenson and was practical only for hauling minerals. The Liverpool and Manchester Railway, which opened in 1830, was the first modern railroad. It was a public carrier of both passengers and freight.
This group was joined by Steam Incorporated and the Railway Enthusiasts Society in running similar excursions using NZR diesel locomotives but the organising group's own carriages. In 1985, NZR agreed to remove the steam ban in conjunction with the centenary of the start of construction of the North Island Main Trunk.
According to the company, the steam engine named Quadrum generates 27% efficiency and runs with 180 °C steam at 8 bar pressure, while a corresponding steam turbine produces just 15% efficiency, requires steam temperature of 240 °C and pressure of 40 bar. The high efficiency comes from a patented crank mechanism, that gives a smooth, pulseless ...
