MRT
The MRT network covers most of Singapore, from the airport in the East to the Industrial zones in the West. Three main lines are in operation with a fourth under construction. The lines are underground in the city centre where all three run close together and cross-overs can be made at several interchanges. Outside the city area the MRT mostly runs on viaducts. Most trips near the centre cost around a dollar, going across the island costs you less than three. Trains drive very frequently from 6am in the morning but stop during the (late) night. (12pm)

The MRT is really very convenient and easy to figure out, the lines and stops are shown on all maps and the information in the stations is very clear. The only disadvantage is maybe that it can get rather crowded around 8am – 9.30 am and 5.30- 7.30 pm.(before abd after office hour).

LRT
In several areas there are connections between the MRT and an unmanned Light Rail system too. These LRT's are mainly in the more outlying resedential areas.
