Do diesel trains smell?

Diesel engines, which are commonly used in trains and buses, release a combination of gases and particulates into the air. These emissions include nitrogen oxides (NOx), sulfur dioxide (SO2), and particulate matter (PM), which can produce a strong, acrid smell.

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.

Greenhouse gas (GHG) emissions are directly related to fuel consumption. According to EPA data, freight railroads account for just 0.5% of total U.S. GHG emissions and just 1.7% of transportation-related GHG emissions. Moving freight by rail instead of truck lowers GHG emissions by up to 75%, on average.

While standing on a train platform, you've probably caught a wiff of an odd burnt odor wafting up from under the train. That smell is the trains break pads girding and producing microscopic dust particles. Just like your car, a train uses brake pads to slow itself.

Diesel locomotive engines are a major contributor to air pollution. The culprits are NOx SO2. Both are readily produced by diesel locomotives and both cause an array of health and environmental problems.

MORE DETAILS

The diesel engine drives an alternator, which produces electricity to run electric motors mounted on the locomotive's axles. The internal combustion engine was a dramatic improvement in efficiency over the steam locomotive, making substantial savings possible in maintenance and the elimination of widespread facilities.
