A Roblox experience owned by Vertex Assembly.

Description (written by the developer; not a statement by this register)

Kingdom Coal is a Ro-Scale game made alone by the creator of Ultimate Rails. This game features newer and higher quality rolling stock, as well as a more dynamic rail layout than previous games. No content from Ultimate Rails games carries over to this as it is a completely separate project. This game has very high detail assets and probably will not run well on mobile devices. Important: There is a slider in game that lets you control your view range. The default is 500 studs and this can be increased to 2000 studs. This game is currently in early access and may have some issues as a result of testing.

Growth history is still building. We hold one measurement for this entry. A trend needs at least two, taken days apart — so this will fill in on its own rather than being estimated. We do not publish numbers we have not measured.

Growth

7 measurements spanning 70 days, net -7. 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 50–59 and does not start at zero.
