Several examples have been cited to illustrate that there are several approaches to reduce pollutant emissions. Deutsche Bahn AG has set itself the goal of significantly reducing pollutant emissions by 2005. The present article sets out measures and moves to reduce pollutant emissions from rail vehicles. Following an overview of the DB diesel traction-unit fleet, the findings from trials and studies carried out by Deutsche Bahn AG are presented. Examples cited are the re-engineering of a shunting locomotive, emission optimization of the diesel engine on a main-line locomotive, the trialling of an exhaust-gas after-treatment unit on a Diesel Multiple Unit (DMU) trainset, and the conversion of a DMU trainset and a diesel locomotive to natural gas propulsion. These studies have led to fuel savings of up to 30 % as well as to a significant cut in the emission of NO(x), CO, HC and particulates.
