Europe's first trains to use batteries as a main source of power have arrived. Hitachi Rail announced last week that 20 tribrid trains—nicknamed “Blues”—are now running on rail lines across Italy.

The trains have a short range of up to 15 kilometers (about 10 miles) on battery alone, but can recharge as they go, using the pantograph (the apparatus on top of the train which connects it to a power line) or by braking, meaning it can recharge multiple times during a journey. Maximum speed is 160 kph (100 mph).
When the electricity stopped, during the running on railway track, the all trains which is running with electric locomotives has stopped. The train will stopped until the power supply start.
Although commonly called diesels, the locomotives actually are electrically driven. The diesel engine drives an alternator, which produces electricity to run electric motors mounted on the locomotive's axles.
Hydrogen fuel cell trains can run on hydrogen with just water and heat being produced as a by-product. These trains are a good alternative to diesel powered locomotives where railway lines are not powered.
The life expectancy of diesel-electric and electric locomotives is expected to be similar—about 25 years. Both types of motive power are subject to technological obsolescence.
Most countries have a freight decarbonization goal. These typically include shifting from road to rail and also electrifying rail (IEA, 2019; OECD/ITF, 2021). This model shows that the rail freight industry could expect to see a positive net present value and emissions reductions globally through electrification.
Besides steam- and diesel-powered locomotives, many trains operate solely on electrical power. They get the electricity from a third rail, or electrical line, along the track. Transformers transfer the voltage from the lines, and the electrical current drives the motors (AC or DC) on the wheels.
Some locomotives collect electricity from overhead cables, while others take power from a third “live” rail on the track. It is very expensive to build the lines or rails that carry the electric current, but electric locomotives are cleaner, quieter, faster, and more reliable than steam or diesel engines.
Most yard-switching and short-haul locomotives are equipped with diesel engines ranging from 600 to 1,800 horsepower; road units commonly have engines ranging from 2,000 to 4,000 horsepower.
Railway electrification in Great Britain began in the late 19th century. A range of voltages has been used, employing both overhead lines and conductor rails. The two most common systems are 25 kV AC using overhead lines, and the 750 V DC third rail system used in Southeast England and on Merseyrail.
