Replay of the exact solution found by the two-stage Gurobi MILP for the collaborative optimization of train timetabling, rolling stock allocation and virtual coupling on the Santiago de Chile L4A line (6 stations, both directions). Model by Michel Verdu Alvarez, Mathematical Optimization, University of Trieste 2025/26.
Trains move along the line as the clock advances. Bars under each station show passengers waiting per direction. Hover a train or a bar for details.
Each line is one service: horizontal segments are station dwells. Hover to inspect, click or drag to jump the replay to that moment.
