See a demonstration of the Westport 15-litre natural gas engine and fuel system with Arrow Transportation Systems and Wastech, hauling trash to Cache Creek, BC, Canada.
The demo was a resounding success and the Arrow drivers and staff were very impressed with the performance. GVWs for the demo were upwards of 60,000 kg.
