Investigation of Exhaust Emissions from a Shunting Locomotive and a Rail Diagnostics Machine

The article is an investigation into the exhaust emission impact of operating a shunting locomotive SM42 and a track diagnostics machine UPS-80-001. The comparison of the two vehicles makes it possible to estimate the overall environmental costs of two different types of rail vehicles operating at their typical work parameters. This was done using selected exhaust emission indicators. It is used to indicate the need for further improvement in vehicle ecology such as hybrid or electric systems. Other solutions are investigated as forms of mitigating the ecological impact of operating such vehicles in or near human population centers.
