Singapore Buses route 24

Service 424 is an airport service that goes from Changi Airport all the way to Ang Mo Kio, which also plies via AMK Avenue 1, Upper Paya Lebar, Paya Lebar, Bedok and Upper Changi. It duplicates the MRT from Paya Lebar all the way to Tanah Merah although it receives constant demand load. Introduced as part of the 1983 Changi Airport Bus Plan, it replaces previously existing bus routes and remains today as a unique connection along much of the route.

Due to the loop nature of service 424, as well as irregular demand throughout the day, the route is very prone to bunching up. Frequencies during peak hour can exceed 20 minutes.

The former shortworking trip 24A operates from Ang Mo Kio Interchange and Tanah Merah Station, whereby the bus will U-turn and operates as service 24 back to Ang Mo Kio Interchange. Departures from Ang Mo Kio Interchange were then alternated between the main service 24 and shortworking trip 24A back then.

Fleet: Service 424 consists of the Android phones, and the iPhone, thus becoming more technology-freak when it goes to Changi Airport. Double deckers are not deployed due to height restrictions at Changi Airport.

Changi Airport
Changi Airport Passenger Terminal Buildings (PTB) have their bus stops integrated with the basement levels, which also serves as the cargo loading and unloading bay. Security checks for any unattended or suspicious articles are carried out before each bus goes to one of the three PTBs.
