I had some time to spare and looked at the map. It shows that several trains passed through the station within the specified time frame. Only two trains didn't. So the argument that he supposedly didn't have any keystrokes or chat messages isn't true. If you look even more closely, you can see someone with a very similar profile picture to his passing through Lacy. I think there must have been some kind of communication. Couldn't it simply be that the moderation or the systems failed miserably here? I don't think it's possible to set the train routes without any interaction.
Around 7:30 PM, the player disconnected, and another player entered the signal box and encountered the same error. Only after a third player entered the signal box was the error resolved, and the trains were able to continue running around 8:17 PM.
If you continue observing the map and assume the locations are correct, both trains are indeed on opposite tracks.
