Is trains bad for the environment?
The transportation sector emits the highest amount of greenhouse gas (GHG) emissions of all the U.S. sectors, with the rail sector contributing 2% of those emissions.
Are trains bad for climate change?
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.

We find that car and motorcycle use for shopping and leisure activities fell more sharply along lines with a larger increase in regional passenger trains. These results indicate that expansions of local passenger railways reduce air pollution due to substitution from cars and motorcycles to trains.
Do steam trains pollute more than diesel?
Diesel engines are much more efficient than steam engines, but the combustion in the steam engine's firebox can be more carefully controlled and, so, possibly produce less of the types of pollution caused by imperfect combustion.
What is the most eco friendly transportation?
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.
Is it unhealthy to live near train tracks?
