Lake Loop Line

The Lake Loop line (LLL) is a subway line in YJJ City, operated by YJJ City Metro. Coloured light blue on the rail map, the line is approximately 1.9 kilometres (1.2 mi) long and serves 6 stations, 3 of which, between the Sun Moon Lake and Lakeside stations, are underground. It runs in a loop from Sun Moon Lake station, located on the West side of Sun Moon Lake, going around Sun Moon Lake via Solutional Park station on the East side of Sun Moon Lake. The line operates for 24 hours a day, with headways of up to 3 minutes. All the trains on the LLL run with a fifteen-cart formation.

It is the first subway line to be built in YJJ City, with service beginning in February of 2020. The infrastructure of the Lake Loop Line has been replaced several times, causing irregular service on the line. Because of its "loop" nature, the line was also notoriously known as one of the laggiest lines on the server, until the TrainDestroy plugin was installed.
