DEF for Locomotives

Diesel railway trains represent a considerable def locomotive scrsource of emissions of polluting agents in the atmosphere. DEF allows the reduction of nitrogen oxides emissions (NOx) in diesel locomotives that are equipped with SCR systems. Several engine manufacturers; such as Siemens, Alstom and Bombardier, have chosen this technology for their new models. Some train operators in Europe have responded early to local or national legislation on NOx limits for trains and are already using DEF.
