SPADding is frustrating, especially as SPADs are seemingly just as likely to be caused by the game as the player. I know once the train is through the red signal the dispatch system is basically broken so reset/recovery is impossible. How about an option for SPAD Emergency Stop. A few metres before the SPAD event the train is stopped dead, instantly, preventing the spad. A message is shown and all the points for the service are wiped but the player can continue with the service when signals permit. (Sort of like bumpers in the ten pin alley!)
