Metrolinx, the regional transport authority for the Greater Toronto and Hamilton area (GTHA), has received a prototype locomotive from Wabtec subsidiary MotivePower.
According to the supplier, it is claimed to be the first North American commuter locomotive to meet the US Environmental Protection Agency’s (EPA) Tier 4 emissions standards.

Originally, the locomotive was built by MotivePower five years ago and was repowered with new QSK60 diesel engines supplied by Cummins to meet the new emissions standards.
Compared with the locomotive’s original Tier 2-compliant engines, the new QSK60 helps to reduce diesel particulate emissions by around 85% and NOx emissions by around 75%.
The Cummins Tier 4 Locomotive certified QSK60 diesel engines will be capable of producing about 5,400 horsepower for traction and auxiliary train power.

The company noted that QSK60 meets the Tier 4 requirements using integrated selective catalytic reduction (SCR) exhaust after-treatment technology, which removes NOx from the exhaust stream, enabling reduced emissions and improved fuel efficiency.
