The train and bus system is called the MRT, and it is extremely easy to ride!
Most people here in Singapore prefer to take the bus. You just tap your card to get in and tap it again to get out. This form of transportation is extremely cheap and useful.
I liked taking the trains and buses here much more than taking the subway in New York City, since the MRT is very clean and cheap compared to the smelly subways and their expensive price.
The trains and bus routes are determined by the most efficient way to reach everyone at an equal distance from any place on the island. The routes take into account the streets and buildings by weaving the train lines through them, while the buses actually go on the straightest paths through the city from one end to another.
