This thesis addresses the challenge of producing fuel-optimal speed profiles for locomotives
by transforming time-optimal profiles. In the time-optimal speed profile, the train
travels over a single segmented railway line with various speed limits for the least time.
Our approach aims to adjust its speed profile by extending its total duration to produce
the fuel-optimal speed profile within that extended time frame. Rail networks are crucial
to the economy, and their demand has been increasing over the years. However, the
minimization of fuel consumption for the described problem has not been studied. Our
approach modifies specific instances of the given speed profile to minimize the fraction
of fuel consumption over time.
The developed iterative algorithm consists of two sub-algorithms that address those
instances, following a greedy approach where the main variables are time and speed. The
study’s results demonstrated that it is most effective to adjust only ”Acceleration and
Deceleration” and ”Acceleration, Cruising and Deceleration” throttle sequences, with
the former always being the best option. Our proposed solution could contribute to
minimizing fuel consumption in railway networks by leveraging the delays created to
avoid collisions at intersections as the basis of the model.
