abstract: Although train modeling research is vast, most available simulation tools are 
confined to city- or trip-scale analysis, primarily offering micro-level simulations of 
network segments. This paper addresses this void by developing the NeTrainSim simulator 
for heavy long-haul freight trains on a network of multiple intersecting tracks. The main 
objective of this simulator is to enable a comprehensive analysis of energy consumption 
and the associated carbon footprint for the entire train system. Four case studies were 
conducted to demonstrate the simulator’s performance. The first case study validates the 
model by comparing NeTrainSim output to empirical trajectory data. The results demonstrate 
that the simulated trajectory is precise enough to estimate the train energy consumption 
and carbon dioxide emissions. The second application demonstrates the train-following model 
considering six trains following each other. The results showcase the model ability to maintain 
safe-following distances between successive trains. The next study highlights the simulator’s 
ability to resolve train conflicts for different scenarios. Finally, the suitability of the 
NeTrainSim for modeling realistic railroad networks is verified through the modeling of the 
entire US network and comparing alternative powertrains on the fleet energy consumption.
