I am interested in the complexity of the railway system in TSW in particular the Signaller. So does the Signaller even exist in TSW and if so what it can do with regards to a train with higher priorities. Or it is just present like to give the permission to proceed if the track ahead is not occupied. Can it prioratize trains so that the passenger train for example can pass the freight one if there is a siding ahead. So train simulator have been developing since 2009, so for 12 years they never talked about the intention to improve or should I say to develop the signaling system in train simulator and than in train sim world games. Signals in these games are just there because they are in real life I guess. But this signaling system is too shallow it just can show red when the following section is occupied by another train. It does not have any capability to dynamically change according to the changing situations.
