This paper evaluates the impact of different freight-wagon grouping and different train scheduling policies by using a simulation model of moving trains on the Iran rail network. Based on three related issues including train scheduling, wagon grouping and train formation, eight scenarios have been designed in addition to the do-nothing. Each scenario investigates the demand of freight transportation of the Iran rail network to determine locomotive emissions consist of CO2, SO2, PM, NOx, CO and HC. This study shows that simultaneous implementation of “un-necessary grouping” and “flexible scheduling” policies can lead to the lowest amount of total emissions.
