Diesel trains may expose passengers to exhaust
Levels of certain airborne pollutants are up to nine times higher in train cars directly behind diesel locomotives than on a busy city street
A new study from U of T Engineering finds that diesel trains may expose passengers to elevated levels of certain pollutants, especially if they are sitting directly behind the locomotive.
“Imagine yourself driving down a busy highway in a convertible, and spending your entire commute sitting behind a very large diesel truck,” said Greg Evans, a professor of Chemical Engineering and director of the Southern Ontario Centre for Atmospheric Aerosol Research (SOCAAR). “That’s comparable to the levels we see here.”
