Interim report: exhaust emission benchmarks for diesel locomotives on Indian Railways

This report gives an overview of the existing diesel locomotive fleet profile on Indian Railways. It deliberates on the methodology and instrumentation quality used for capturing emissions data from the locomotives. It also explains in brief the compliance protocol proposed for certification, in-service and production line monitoring of the emission performance of diesel locomotives through their useful life. The report concludes with an interim recommendation proposing emission standard benchmark for ALCO and HHP (EMD) type of locomotives.
