National Railway Administration: There is a large inventory of diesel locomotives in the railway market, and multiple measures are being taken to promote the replacement and update of old diesel locomotives.

In order to accelerate the green and low-carbon transformation of railway locomotives and ensure the orderly implementation of the transformation of the power source system of old-type railway internal combustion locomotives, the National Railway Administration has organized the preparation of the "Regulations on the Management of the Transformation of the Power Source System of Old-type Railway Internal Combustion Locomotives" and is now soliciting public opinions. It is reported that the preparation of these regulations is an important measure to promote the green and low-carbon transformation of railway locomotives. As core rail transportation equipment, the level of green and low-carbon of railway locomotives will directly affect the energy efficiency and environmental protection benefits of railway transportation. The preparation of the regulations is a specific embodiment of multiple measures to promote the elimination and renewal of old-type railway internal combustion locomotives. The railway internal combustion locomotive market has a large stock, a wide range of applications, and a large difference in service life. In response to the needs of green and low-carbon development of railway equipment, industry units have already explored examples of the transformation of the power source system of internal combustion locomotives, reducing the fossil energy consumption and atmospheric pollutant emissions of railway locomotives. The preparation of these regulations provides relevant policy support to ensure the orderly implementation of the transformation of the power source system of old-type railway internal combustion locomotives.
