The private railway company Heavy Haul Power International (HHPI) transports large quantities of bulk material by rail.
Although this type of transportation is already one of the greenest, HHPI constantly seeks and introduces new initiatives to find and leverage additional improvements for the health of people and the environment.
As part of these activities, HHPI put the enzyme fuel additive through its paces to explore the potential for soot emissions improvement. Over a period of four months, XBEE was used in a heavy freight locomotive, a Class 66.
Before and after the use of XBEE, exhaust emission tests were performed in Bremen with the help of SGS TÜV Saar and Deutschen Bahn AG.
