Description

Formerly known as the Official Build your own DOORS group. Welcome to the official Trainz group, the creator of Build your own DOORS! This group isn't just for Build your own DOORS, but it IS, however, a group for all the fans of my work. I post random stuff on the group wall, and have recently continued making Build your own DOORS. All credits go to LSPLASH for making DOORS. They are the reason I even made the game (obviously) Join the group if you want to, I don't really care. want to join another group of mine!? https://www.roblox.com/groups/33627233/the-sillies#!/about only for those who are silly

2 measurements spanning 4 days, net -1. Dots are measurements; the straight line between them is drawn to join them, not to claim we know the path taken in between — snapshots are recorded only when a count changes, so gaps mean “no change observed”, never “interpolated”. The vertical axis spans 756–757 and does not start at zero.
