History

An old schematic map of the subway system, about 1 month after server launch

The Spawn Subway was the first train service on the Linuxworks Server. In its first working setup (about 1 week after server launch), it featured two lines and 5 stations:

The network quickly expanded, line numbers were assigned incrementally as more lines were opened.

Interlocking

The Spawn Subway (and South Forest Subway as well) uses a "handmade" LuaATC setup to operate trains. Wall signals are used to tell whether a subway train can proceed into the next section. A section starts and ends right after a station. A train frees its current section and blocks the next section in the moment it departs from a station. When there's a diverting junction, one such signal exists per diverting track.

In places where a track crosses another track, one of the stations(typically the one closer to the crossing) gets another signal which is controlled by trains on the other crossing track, passed in as "osig". The train will only depart if both the section signal and the crossing signal are green. This mechanism is also used for single-track lines on the Mountain Railway.

The initialization code can be viewed for reference at [1].

From 2019 on, parts of the network were upgraded to use the advtrains interlocking system. The first section to be equipped with interlocking was the shared section of lines 1 and 4 between Origin and Coulomb Street, to solve the problem of continuous train jams on said section. Any extensions built since the TSS Update use interlocking, such as Line 6 from Coulomb Street northward. Existing lines that have been upgraded include Line 4 on its entire length and South Forest Subway.

Метро-2

It is rumored that ⚖️ Och_Noe operates a secret second network deep underneath the official network, linking up various industrial locations. Houwever, no official details exist on the system and information on the system remains speculative.
