Chapter 4 Subway Trains

Chapter 4 of Mirror's Edge has several sections where the player has to cross train tracks in order to progress.

Train Cycle
The trains driving at Ryding Park Station and in the tunnels have a cycle that is slightly random. The game logic is implemented in Kismet. The first train drives immediately after the respective sub-level it resides in has been loaded. This sub-level is Subway_Plat_Spt for the Ryding Park trains and Subway_Tunnel_Spt for the tunnel trains. The animation lasts for 15 seconds. After a random delay between 5 and 10 seconds, the next train animation starts. This means that the train cycle is between 20 and 25 seconds.
