Do trains still burn coal?

No, they were phased out many decades ago on commercial railways. There are still some steam trains running on preserved railways for steam enthusiasts. Coal-fired steam engines were made uneconomical on non-electrified routes by diesel engines. A diesel costs vastly less to operate, is more reliable and safer.

Freight and passenger rail rely almost exclusively on diesel power. The latest diesel innovations contribute to cleaner air and reaching climate goals. New battery electric and hydrogen options are under development.

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.

It found that passing trains carrying coal add on average 8 micrograms per cubic meter of air (ug/m3) to ambient PM2. 5 pollution. That is 2 to 3 ug/m3 more than freight trains contribute.

Q. Modern trains use electricity as their fuel.

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.

MORE DETAILS

Most high-speed trains run on conventional tracks similar to conventional gauge systems, but built with stronger material. The train on such a track is likely to have two synchronised engines (power cars), one at either end. Most receive power from roof-mounted pantographs and overhead supply lines.

Rail is among the most energy efficient modes of transport for freight and passengers - while the rail sector carries 8% of the world's passengers and 7% of global freight transport, it represents only 2% of total transport energy demand.

Coal Storage and Transportation Typical coal railcars can carry 80 to 125 tons per car and the average load is 100 to 110 tons.
