The article discusses issues related to the assessment of pollutant emissions from a railbus during transport work. The test object was a rail vehicle equipped with two diesel engines with a total power of 780 kW, Stage IIIB homologated. Measurements were carried out on the route Poznań-Wągrowiec in two directions. During the tests, the vehicle performed a transport service, where the number of passengers was counted. For the completed cycles, the average number of people was 82 and 18. Based on the obtained data, the vehicle operating conditions and emission indicators were analyzed, which were related to the number of passengers. A dimensionless toxicity index was also determined.
