Diagram of the train network construction scheme. White station nodes α, β, and γ represent the physical stations and red dashed edges represent access links connecting the station to each of its platforms. Each type of train on each train line is represented by a separate platform node (black nodes) which are connected to each other by train lines (gray) at different stations and transfer edges (blue dashed lines) at the same station. In this example, lines 1+2 and 3 run on the same tracks and both use stations α and γ, but line 3 represents an express train that doesn’t stop at station β. Only the station nodes are connected to nodes of the other transportation networks
