is a physical loop of stations on the map
. It is distinct from a loop
. The most obvious example of a ring is the Circle line; two others are the Grange Hill loop
and the loop around the four Heathrow Terminals. Rings may also be referred to as circles
. The important thing is as far as possible to avoid confusion with loops
as loops have an entirely different significance within the game.
Rings are often used for token rings, and can also allow a player to straddle to another station on the same line.
