Is high speed rail powered by electricity?

High speed trains run on electricity instead of diesel fuel. Because much of the world's electricity is still generated at fossil fuel burning power plants, high speed trains do contribute to carbon emissions, however the climate impact of one train is significantly less than that of many personal vehicles.

Most passenger trains, however, make many intermediate stops, and the trains must be sized to meet the maximum demand along the route. As a result, many trains tend to be relatively empty for much of their journeys, greatly reducing their energy efficiency.

In fact, the percentage of electrified rail is not even 1%, but the only source I had indicated that it was under 1%, so I rounded up. Meanwhile, India is at 83% rail electrification, and is ahead of schedule to achieve almost 100% grid-tied electrification.

The Swiss rail network is the largest fully electrified network in the world and one of only eleven to achieve this. China has the 2nd largest electrified railway length with over 70% of the network, after India overtook china having almost 80% of its railway network electrified.

In the 1930s, the system was adapted for streamliners, the fastest trains of their day. Diesel–electric powerplants became popular because they greatly simplified the way motive power was transmitted to the wheels and because they were both more efficient and had greatly reduced maintenance requirements.

Building high-speed rail systems require steel and concrete, the manufacturing of which typically generates greenhouse gases. Trucks, bulldozers, and other construction site equipment also consume energy. Thus, during their long construction phases, high-speed rail projects add greenhouse gases.

According to a study on HSR in France and China by the International Union of Railways, “the carbon footprint of HSR can be up to 14 times less carbon intensive than car travel and up to 15 times less than aviation travel, even when measured over the full life cycles of planning, construction and operation of the ...

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.

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.

Disadvantages of electric traction include: high capital costs that may be uneconomic on lightly trafficked routes, a relative lack of flexibility (since electric trains need third rails or overhead wires), and a vulnerability to power interruptions.
