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.
Looking at traffic fatalities per mile traveled in the U.S., analyst Todd Litman found that riding commuter or intercity rail is about 20 times safer than driving; riding metro or light rail is about 30 times safer; and riding the bus is about 60 times safer.
truck and auto safety record. Riding the railroad is far safer than traveling in a car or truck. As many know, driving on highways with high truck density can be a harrowing ride.
