Maintaining the environmental advantages of rail transport

Regulations covering the emissions from diesel engines in rail vehicles, where they exist, have not kept pace with the improvements made to the emissions from road vehicles. However, catalytic exhaust treatment can be used in rail applications to maintain the environmental advantage offered by the rail sector. The CRT® and SCRT® systems are particularly suitable for these applications.

The first CRT® systems were fitted to DMUs (railcars) in the mid-1990s and the longest-serving of these have now demonstrated 1.5m km of effective and trouble-free service. Experience shows that these systems are as effective in retrofit applications on rail as they are on road vehicles.

Johnson Matthey also has first hand experience of the application of exhaust aftertreatment systems to locomotives and track maintenance vehicles.

It is predicted that exhaust treatment will be needed to meet the emissions standards for new engines already agreed by the European Union (dir. 2004/26) and proposed in the United States (EPA ANPRM: 69 FR 39275-89).
