Non-road fuel consumption and pollutant emissions FOEN 2008 96 8.7.2 Emissions Railway vehicles have a relatively lengthy service life, and their average age is therefore fairly high. This means that the specific emissions of diesel locomotives are disproportionately high. Railway vehicles produce comparatively high levels of nitrogen oxides (630 tonnes p.a.). The calculation model assumed that a fairly high proportion of railway vehicles have been retrofitted with particle filters. The level of PM emissions (23 tonnes p.a.) is comparatively low (Fig. 49, top). The emission factor for railway vehicles is approximately 2.0 grams of PM per kilogram of fuel, whereas the factor for ships, for example, is 3.0 grams per kg of fuel. Development of pollutant emissions from 1980 to 2020 The level of PM emissions will decrease significantly over the next few years thanks to the continued retrofitting of older machines with particle filters (Fig. 49, bottom). In the period from 2005 to 2020, nitrogen oxide emissions are expected to fall by around 50%.
