title: NeTrainSim
version: 0.1.2
date-released: 2023-07-23
doi: 10.2139/ssrn.4377164
abstract: Although train simulation research is vast, the majority of simulation
tools available are confined to city- or trip-scale analysis, primarily
offering micro-level simulations of network segments. This paper introduces
the NeTrainSim simulator for heavy long-haul freight trains on a network of
multiple intersecting tracks. The simulator is an attempt towards simulating
the entire train system for energy consumption analysis. Four case studies
are conducted to demonstrate the simulator’s performance. The first case
study validates the model by comparing the NeTrainSim’s output to empirical
trajectory data using a basic single-train network. The second demonstrates the
train-following model considering six trains following each other. The
remaining case studies highlight the simulator’s capability in resolving
train conflicts for different possible scenarios. Finally, the suitability of
the NeTrainSim for the modeling of realistic railroad networks is verified
through the implementation of a sample network located in Cook county, Illinois.

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.
