Frumple released a timelapse of the line when the server opened.
The Red Line is a line on the Minecart Rapid Transit system. It was the last MRT line built by Frumple and is the shortest, at only 13 stations. It runs from west to east between Mycelium and Audenville. It is mostly underground and is on the lowest level of Spawn station, below the Blue, Green and Yellow Lines.
