The locomotives weigh between 100 and 200 tons (91,000 and 181,000 kilograms) and are designed to tow passenger-train cars at speeds of up to 125 miles per hour (200 kph). Siemens' modern engines produce up to 4,200 horsepower, and the generator can turn this into almost 4,700 amps of electrical current.
The average fuel consumed per kilo- meter for all passenger and cargo trains is 7.97 L/ km. This value for local, trafficking, railway track laying and maneuvering trains is 7.92 L/km.
Trenitalia's Paris to Milan route was first introduced in December 2021, serviced by Hitachi Rail's ETR1000. This super high speed train travels at 300km/h - with the ability to go400km/h if not limited by track regulations - making it the fastest train in Europe.
One of those is the country's impressive high speed rail infrastructure. The network consists of 40,000km of tracks, giving China the title of most high speed rail in the world. The technology behind China's high speed trains represents a historic breakthrough in long distance travel.
Steam locomotives can be more powerful than diesel locmotives depending upon the size, capacity, weight and other specifications of the different engines. Steam locos used coal and/ or fire wood to heat the water, and hence the amount of heat and steam generated would not be/ can't be even all the time.
A train engine requires about a hundred litres of fuel to get it started. So it wouldn't be economical if the engine is stopped and started frequently. This apart, if the engine is stopped, the moving parts' lubrication will also come to a halt.
Fastest Train in the World – 357.2 MPHThe current world speed record for a commercial train on steel wheels is held by the French TGV at 574.8 km/h (357.2 mph), achieved on 3 April 2007 on the new LGV Est. The trainset, the track and the cantenary were modified to test new designs.
As of August 2022, the fastest train on Earth, based on its record speed, is the Japanese L0 Series Maglev with a record speed of 603 kilometers per hour.
1: Shanghai Maglev - 460 kph/286 mph (China)Based on German technology, the Maglev trains fly along an elevated track, the powerful magnets providing a super-smooth, friction-free ride.
A foundation of Einstein's Theory of Special Relativity is that nothing can travel faster than the speed of light in a vacuum; this is the effective speed limit for the Universe!
As with internal combustion engines that are used in more traditional ways, engines used as power generators in diesel electric trains are also considerably more efficient thanks to the use of turbochargers.
Modern locomotives use electric traction instead of gears as electric traction is much more flexible than gears. Diesel fuels generators from the combustion engine and transform the energy using an alternator, which runs the traction motors.
