Often, a duplicate set of either platforms or tracks are needed, because people demand frequent and bi-directional train services:

              ____▢▢▢>              /―――――――――――――――――――――▢▢▢>――――――――――――――― Cityline Eastbound
――<▢▢▢―――< [Riverton] >――――――――――――<      [Citycore Sta.]     [Findist Sta.]
              ￣￣￣￣￣              \―――――<▢▢▢―――――――――――――――――――<▢▢▢―――――― Cityline Westbound

and tracks need regular maintainance, for which sections and lines has to be closed or capacity significantly reduced:
