Do electric trains cause pollution?

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.

“When you take into account the production of railroad equipment and tracks, all of that is very carbon intensive as well,” says Hamilton. “Take the entire picture and trains are actually more polluting than the road buses, even though buses all run with dirty diesel fuel.”

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.

If we take an overall view of the transport sector, 71% of transportation related carbon emissions come from road users, whereas only 1.8% of emissions stem from rail travel. So in absolute terms, trains are responsible for a lot less emissions than cars.

Trains. Besides walking and biking, traveling by train remains one of the greenest and most environment-friendly options when getting around. Regardless if electric or diesel-powered, trains emit between 66 and 75 percent fewer carbon emissions when compared to cars and airplanes.

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.

One of the biggest environmental benefits of trains is that they consume far less energy than other types of transport. It takes a huge amount of fuel to get a plane carrying hundreds of people airborne, whereas trains are streamlined, require much less energy to move, and are increasingly able to run on electricity.

Compared to flying, using the train emits on average six times less GHG emissions.

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.

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.

Air travel is convenient and can transport large numbers of passengers, but it has a high environmental impact due to carbon emissions and fuel needs. Gas-consuming vehicles provide convenience and flexibility but have high carbon emissions and contribute to traffic.
