With the rapid development of the Chinese high-speed railway (HSR) network, more and more railway lines are becoming oversaturated, leading to inefficient operations and reducing the service quality. To improve the network’s performance, this paper proposes a profit-oriented line planning model for collaboratively optimizing the operational costs and passenger travel times. Due to the complexity of the problem, an iterative approach is designed to solve the problem efficiently. Two case studies are implemented to verify the performance of the approach. The results of the small example show that the best found line plan can save up to 6% of the travel time compared to the initial solution and improve the profit with 2%. The proposed iterative approach also performs well in searching for high-quality solutions on the large railway network.
