As an island microstate, Singapore has no national rail system as such. The Malaysian national operator, KTMB, provides passenger service to a Singapore terminal at Woodlands - see Malaysia.
There is an extensive metro system covering most parts of the island. The system is operated by two separate companies:
- SMRT: East West Line, North South Line, Circle Line, Thomson-East Coast Line
- SBS Transit: North East Line, Downtown Line
Despite the split in ownership, information and fare systems are shared. See also UrbanRail.
- Gauge: standard

Note that the LRT systems at Punggol, Sengkang and Bukit Panjang are rubber-tyred peoplemovers, not conventional railways.
