The underground of Singapore is called Mass Rapid Transport or just MRT. There are two lines, the Northsouth which mostly will use if you live in the city centre and the Eastwest which was recently extended to Changi airport. It is amazingly clean and safe. However, it is very crowded during the rush hours just like anywhere else.

There are 48 stations on the MRT system, 15 of which are underground, 32 elevated and one on the surface. Major transfer points are at City Hall, Raffles Place and Jurong East. All underground stations are air-conditioned and are enclosed by glass-doors similar to those found on the Newark International Airport monorail.

The current MRT consists of two lines - an east-west line from Pasir Ris to Boon Lay and a semi-loop from Jurong East to Marina Bay via Woodlands. It was designed to link housing areas with the central business district. Accessing the CBD in Singapore during rush hours by automobile requires a special permit because of traffic congestion, an interesting way that the Singapore government tries to promote the use of rapid transit. The fare structure is zoned with fares ranging from S$0.60 to S$1.80.

Access to the system is through the use of fare cards, either single use or through stored value cards called Transit Link Fare cards. The tickets are cheap, you can normally buy a travel card which looks like a business card and then load it with an amount of money, you validate it when you enter the station and when you reach your destination you validate it again and the machine calculates the fare of your journey and deducts the amount from your card. The fares range from $ 0.70 to $ 1.60 (Singapore dollars). The maximum value the fare card holds is $ 50.00. The MRT operates every day from 5:30 am to 12:30 am. Peak periods are Monday to Friday from 8:00 am to 9:00 am and 5:15pm to 6:30 pm. and Saturdays from 8:15 am to 9:00 am and 1:00pm to 2:30 pm.

Although the MRT Subway can get a bit crowded on some lines at rush hour times, but you will find it to be a delight to use as you will not have trouble getting stuck in the traffic jam.
