The pollutants also reached southern Canada and North Carolina, posing significant risks to aquatic flora and fauna.
A new study published in Risk Analysis has found that longer freight trains are more likely to experience derailments, with a 100-car train being over twice as likely to derail than a 50-car train. This increase in risk could lead to higher rates of accidents and greater safety concerns for the rail transport system.
A new study published in Risk Analysis found that longer freight trains are more likely to derail compared to shorter trains. The research, which analyzed US freight train accidents between 2013-2022, showed a 24% higher risk for 200-car trains.
