Love these style of games. I would love to know more about the lore of this setting.
Having some sort of guide book on how to spot anomalies would be helpful. A lot of the rules are implied, but it might be useful to remind players that the destination has to come after the departure location. I also didn't realize that anyone arriving before the train was considered anomalous. (I didn't see any hint that the actual timing was off so I assume the train was simply running late.)
