Railway electrification stands at about 37 percent of the global track length in 2018 (based on International Railway Union [UIC][1] data); this percentage has been growing over the last two decades by amounts that vary widely from year to year.

Trains are powered either by diesel or electricity. Electric traction is currently responsible for around two-thirds of the freight and more than half the passengers on railways. But, electric traction is just 37% of Railways' overall energy efficiency costs.
All Electric Trains in The Netherlands Are Now 100% Wind-Powered. The Netherland's national railway company, NS, has announced that all of its electric passenger trains are now 100 percent powered by wind energy.
The Association of American Railroads claims 220000 km. Capital costs for electrifying something that large would be just a bit high, and with continuing subsidies for oil the cost savings simply aren't there. Additionally, the vast majority of the US rail network is privately owned and operated by dozens of railroads.
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.
Electric trains have always had no direct carbon emissions because they are run entirely by internal electric motors. However, the means of generating the electricity used to power these motors was predominately by burning fossil fuels or coal, both of which produce a large amount of carbon emissions.
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.
Today's rail networks largely consist of electric trains 'tethered' to electric overhead and live rail systems. However, this is not feasible everywhere due to the high infrastructure cost/mile, remote geographic locations, and the practicality of building through tunnels and bridges.
As of 2021, Germany had a railway network of 33,399 kilometres (20,753 mi), of which 20,540 kilometres (12,760 mi) were electrified and 18,556 kilometres (11,530 mi) were double track. Germany is a member of the International Union of Railways (UIC).
A few early subways used steam engines, but in most existing subways, the trains, tunnel lights and station equipment all run on electricity. Overhead wires or an electrified rail known as the third rail supplies power to the trains.
Today's train locomotives are already quite fuel efficient, especially compared to trucks. In fact, trains can haul one ton of goods an average of more than 480 miles on just a single gallon of fuel, making them 3-4 times more fuel efficient than trucks.
Japan: Japan is often praised for having one of the world's most efficient and punctual railway systems. The country is known for its high-speed Shinkansen (bullet trains) and extensive network of commuter and regional trains. Japan's commitment to safety, cleanliness, and customer service is also noteworthy.
While the US was a passenger train pioneer in the 19th century, after WWII, railways began to decline. The auto industry was booming, and Americans bought cars and houses in suburbs without rail connections. Highways (as well as aviation) became the focus of infrastructure spending, at the expense of rail.
“On most of the approximately 500 routes in Germany that are currently served with diesel, [batteries are] the more efficient and cheaper solution,” Obst observed. “These are usually between 40 and 80km long, which you can easily travel with a battery train.”
Out of the European Union member states, Luxembourg had the highest share of electrified railway systems, at 91 percent. The EU-27 average stood at 56.6 percent in 2020.
