What will happen to all these black and white farewells at stations without thick clouds of smoke and steam? Earned. Of course, they became obsolete long ago, replaced first by diesel models, then by electric models, and finally by high-speed maglev trains. However, some of the latest models quickly lose momentum again. French rail maker Alstom and British company Eversholt Rail have joined forces to develop a new generation of hydrogen-powered locomotives.of technology project We plan to adapt older diesel models instead of building them from scratch. Fittingly, this would happen in the cradle of a steam locomotive. Richard Trevithick In 1804 the first prototype was built.
The consortium will retrofit existing Class 321 trains in service in the UK with hydrogen systems and operate as Hydrogen Multiple Units (HMU), codenamed Breeze.the goal of this innovative project The goal is to realize clean and environmentally friendly trains that can run without emitting harmful carbon dioxide, even on routes that are difficult to benefit from electrification.another Advantages of these adaptive engines Not only will it fit in older locomotives, but hydrogen tanks will be installed at the beginning and end of the train, giving passengers more space.by using this innovative technology, the new engine runs quietly at speeds up to 90 mph with a range of 620 miles. The contract covers the conversion of 100 trains to be operational by early 2021.
Currently, less than half of UK rail lines are electrified, so diesel engines must be used. This is one of the country’s decarbonization goals. technology It should be phased out by 2040.
The UK isn’t the only country working on this new system, though. In September 2018, the first of his Coradia iLint hydrogen trains began operating in Germany, transporting passengers daily in a clean and sustainable manner.
The fastest steam locomotive in history
Speaking of steam locomotives, people tend to think of them as venerable machines that slowly march while exhaling smoke, but in fact, in the early 20th centuryth The century given by the conventional steam engine diesel technology Train execution for their money.
On July 3, 1938, the steam locomotive was nicknamed MallardBuilt with double funnels and double Kylchap blastpipes, the 165 propelled the 165 at breathtaking speed. Driver Joseph Duddington flew it that day at 126 mph, claiming the class world speed record that has not been broken since.
After its retirement in 1963, the old Mallard is now in York’s National Railway Museum, with a small commemorative plaque documenting its power.
