Route History

Introduced in 1987, Service 27 is one of six daily services to Changi Airport, linking the Airport Passenger Terminal Buildings (PTBs) 1, 2 & 3 with the residential towns of Tampines, Sengkang, Buangkok and Hougang. By using the Tampines Expressway (TPE) between Tampines and Sengkang, it serves as an important route connecting the two towns. In fact, most of service 27’s demand comes from the Sengkang – Tampines sector, with Shortworking Trip 27A supplementing AM Peak demand towards Tampines and PM Peak downroutes from Tampines Avenue 4 heading back to Hougang.

From Tampines Central, Service 34 also heads to the Airport, but takes a longer route through Tampines East. In addition, Service 72 offers comparable travel time between Tampines Central and Hougang, but does not service Buangkok or Sengkang.

Changi Airport:

Service 27 serves Changi Airport Terminals 3, 1, 2 & 4 in order. It does not serve Terminal 4.

Changi Airport Passenger Terminal Buildings (PTBs) 1, 2 and 3 have their bus stops integrated into their basement levels, which also serves as a cargo loading and unloading bay. Security checks for any unattended or suspicious articles are carried out before a bus enters Terminals 1, 2 and 3. Bus Captains may take a short toilet break at Terminal 2. Because of height restrictions, double-decker buses are unable to enter Changi Airport basement.

Occasionally when Changi Airport basement is closed, buses will be diverted to to T1/T2/T3 Departure Drive where a temporary bus stop will be set up.

A fleet restriction for Changi Airport appears to be in place, with only Mercedes-Benz O530 Citaro buses deployed on airport-plying bus services.

Announcements for passengers to inform the Bus Captain if they see any suspicious person or article are played on board public buses at Changi Airport as well.

    Service 27 is notorious for its short run time and speeding buses.

These name are the new bus stops and where should it be placed and lifts and stair case for people to go up

      I dont think they should add in more stops. Already overcrowded in just 3 stops… They shld add more buses instead.
