Hi,
yesterday I was dispatching Lódz Widzew. Because of a mistake of mine I wanted to give a train from Chojny to Widzew a written order in Lódz Dabrowa, because there's no Sz possible. But it isn't possible to choose a train there. You can only choose trains that are in the stations Widzew or Marysin, where you also have the option to give them Sz. The only location, where the written orders really would make sense and would be very helpful, is Lódz Dabrowa, because it hasn't Sz and is blocked, when you do a mistake. In my case I could rejoin to solve this problem. But when you would do a mistake while driving to Chojny on track 2, the train would possibly stuck there.
