The Phase-1 network of Namma Metro consists of two corridors viz. East-West and North-South.

East-West corridor is named Purple Line

North-South corridor is named Green Line

The two corridors intersect at Kempegowda station which is a two level interchange station. A commuter who intends to travel from a station in one line(say Trinity in Purple line) to a station in another line (say Peenya in Green line) will have to change the train at Kempegowda station without coming out of paid area. The commuter can buy a single token for the complete journey.
