A. GO’s MP40 diesel locomotives use the best, cleanest technology available, meeting all US Environmental Protection Act (EPA) Tier 2 Emission Standards that are equivalent to the new US EPA Tier 3. The Tier 4 Standard will reduce particulate matter by 70 per cent, and NOx by 76 per cent. There are no Canadian emissions standards for diesel trains.
