High Capacity Buses

Double Decker Buses
Double-decker buses are the oldest and most common type of high capacity buses that are operated by public bus operators in Singapore. They consist of two levels (or decks) - the upper deck and the lower deck. With 55 additional seats on the upper deck (for the modern air-conditioned double deckers), they provide capacity through the availability of more seats in comparison to rigid buses. However, standing is prohibited on the upper deck due to safety reasons.

Bendy buses
Bendy bus is the second most common type of high capacity buses that are operated by public bus operators in Singapore. They consist of front trailer and rear trailer. There are 25 additional seats.
