Service 53 is an inter-town route connecting the residential towns of Bishan, Serangoon Central, Lorong Ah Soo and Pasir Ris with Changi Airport. It also serves the role of connecting Serangoon MRT to outlying housing estates. This service also compliments Service 81 between Pasir Ris and Serangoon Central, travelling via Tampines Expressway (TPE) and Kallang-Paya Lebar Expressway (KPE) in both directions, offering a quick bus connection between these areas.

Between Bishan and Pasir Ris, service 53 plies the shorter route compared to service 58 and 88, via the Kallang-Paya Lebar Expressway (KPE). In Bishan, Services 53 and 58 both start their eastbound trips towards Pasir Ris (and Changi Airport, only for service 53) from Bishan Interchange, while services 58 and 88 call at the bus stops outside the Bishan MRT Station (53231 Bishan Stn & 53239 Opp Bishan Stn). In Pasir Ris, service 53 calls at the bus stops in close proximity to Pasir Ris MRT station along Pasir Ris Drive 1 (77031 Aft Pasir Ris Ctrl & 77039 Bef Pasir Ris Ctrl), while services 58 & 88 terminate at Pasir Ris Interchange.

Changi Airport:

Service 53 serves Changi Airport Terminals 3, 1 & 2 in order.

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.
