Not to be confused with the present day Robloxity Metro, or the Robloxity Metropolitan Light Rail Network.
The Robloxity Subway is a partially completed, but never opened subway line in the city of Robloxity. It was originally planned by the Robloxity Street Railway Co. in 1918 to create an alternative to the congested surface streetcars. Currently, the abandoned tunnels constitute the largest abandoned rapid transit tunnels in the country. While tunnels were constructed from 1936-1939, they did not open due to the outbreak of Roblox War II.
