30.11.2007 16:00 | Juhana Hietaranta: | Maybe some commuter train (R, H or Z) had just left from Kerava (note the position of the junction 613) and a train dispatcher wanted to let this train pass Kerava without stopping..? Or then for example a Z-train to Helsinki had just been coming soon after this train..? (This slower train would have had to wait...) In every case, using not-so-usual tracks is not difficult; a train dispatcher only have to press some buttons ;) So, if there was an empty (unusual) track to let this train to go, why wouldn't it have been used? :) (Käyttäjä muokannut 30.11.2007 16:04) | |

30.11.2007 21:11 | Juhana Hietaranta: | Yes, that do is right. Being "creative" is not enough, you must also know properly what you're doing... But I've seen by my own eyes how talented train dispatchers have done that kind of solutions successfully :) | |
