Loop Services

Loop routes (or circular routes) are a unique form of bus routing. As its name suggests, a loop route only has one terminus, unlike bi-directional routes or uni-directional routes with no return trips. Buses leave the terminus and complete their route by returning back to the same terminus. Loop routes provide continuous bus service along a longer stretch of road compared to an ordinary bi-directional route. Technically, passengers can pay a fare for the full route and return back to the originating bus terminus. However, some exceptions do exist, and passengers may be required to alight at the looping point.

The point where a loop service turns back towards its starting point (and merges with its own forward route), is known as a looping point. After the looping point, buses resume their return route back to the bus terminus. Looping points can be named after street names (e.g. Changi North Crescent) or places of interest near the looping point (e.g. Singapore Zoo). However, not all loop routes have a defined looping point.

Some special cases do exist with loop routes. For example, some bi-directional trunk routes operate like loop routes, and drivers do not park their buses nor get a layover at the bus interchange / terminal. Some loop routes have multiple en-route looping points, and some have looping points within restricted areas.


EDS Programming for Loop Services

Selected loop services, such as long distance looping trunk services, have their Electronic Display Systems (EDS) programmed with both directions of the loop route (similar to bi-directional trunk services) and bus drivers will switch the directions on their EDS at the looping point.

However, most short distance looping trunk and feeder services have an EDS display of both the terminus and the looping point, hence eliminating the need for switching the EDS display.

Bus Service 502, currently operated by SMRT Buses, only has a single EDS display, indicating the service type and service number (i.e. EXPRESS 502), which was brought forward from its time under SBS Transit operations since 2009. Looping short trip services adopt similar EDS displays as uni-directional short trip services (i.e. Ends at / Terminates at destination, with the exception of full day short trip Bus Services 912A and 912B).

Most looping terminating trips of their parent services also adopt similar EDS displays as uni-directional short trips (i.e. Ends at / Terminates at destination), except SBS Transit Bus Services 291 and 293.

Since early 2025, in a bid to improve the visibility of EDS displays, many buses operated by SBS Transit (specifically Mercedes-Benz Citaro buses), and all buses operated by Tower Transit and Go-Ahead, began adopting a front EDS display which indicates the origin/destination and looping point only for their looping bus services.

Refer to the EDS Programming for Bus Services article for more details on the different types of EDS displays in use for looping bus services.


Listed below are a few types of loop routes in Singapore. Some bus routes may fall under multiple categories:


1. Looping at bus interchange / terminal

Some loop routes loop at bus interchanges or terminals, without having any layover there. This is usually because they need to quickly return to their originating terminus without making unnecessary layovers, or to avoid the need for setting up a driver’s kiosk there when the bus company does not operate any other routes into that interchange or terminal.

2. Point loop routes

Let’s have a service from point A and looping at point B. Because of geographical limitations (e.g. no space for a bus terminus) or for various operational reasons when the bus should return to point A as quickly as possible, the service will be operated as a loop route. Point loop routes routes are characterized by a single looping point (e.g. a roundabout / three point turn) and heavy duplication of their forward and return journeys. Most loop routes in Singapore fall under this category.

3. Area loop routes

Let’s have a service from point A and looping at point B. Because of geographical limitations (e.g. no space for a bus terminus) or for various operational reasons when the bus should return to point A as quickly as possible, the service will be operated as a loop route. Area loop routes do not loop around a point, but over an small area instead, using multiple turns at various junctions. They are characterized by heavy duplication of their forward and return journeys. Most loop routes in Singapore fall under this category.

4. En-route looping points

Some bus routes (including bi-directional routes) make a loop around selected stretches of roads to provide better accessibility to residential blocks, industrial developments and MRT stations. However, these looping points are not considered the official looping points for the loop routes, but are en-route looping points for selected bus services before proceeding towards their official looping points.

5. Clockwise/Anti-clockwise loop routes

In some situations, a loop route will be required to connect points A, B and C. An ordinary loop route going through A, B and C in order may face some problems. For example, there may be high passenger demand from B to A, as well as from C to A. This creates overcrowding on the route, as well as unnecessary travel time for passengers at B. Also, although passengers at B will be able to alight at C, passengers at C will not have bus connections to B. This is when clockwise and anticlockwise loop routes are launched, one routed as ABCA and the other routed as ACBA, to cater to the needs of different commuters.

6. Two-part loop routes

Some loop routes are actually two loop routes combined into one, and the route stops at the original terminus midway through the route. Both the first and second leg serve different areas (ABACA). This system allows passengers to travel between the areas served by both legs of the route. This is most commonly seen in the formerly Intra-Town/Townlink branded routes. To differentiate between the two legs of the route, SBS Transit used to implement a red/green plate system for the two legs.

Buses on dual loop feeder services will reflect the “T” suffix on the service number during the 2nd loop if the bus will terminate at the interchange. Otherwise, the bus will continue on its 2nd trip (i.e. 1st loop again) after finishing the 2nd leg. Drivers usually do 2 trips (i.e. 4 loops) of the service before going for their break.

Buses on Service 92 will reflect the “T” suffix on the service number if the bus will terminate at Ghim Moh Bus Terminal.


7. “Infinite” loop routes

This variant of loop routes allow passengers to remain onboard the bus at the bus terminus. The passengers can wait onboard until the bus departs on its next trip. The distance fare will be accumulated for both stretches of route (return and forward trip) once the passenger taps out, or a passenger pays a cash fare equivalent to the distance he traveled. This form of loop route technically allows passenger to stay onboard for as long as they like, as the fare will only be charged upon alighting ( A)

92 Ghim Moh Ter ↺ Science Pk Dr/Mt Sinai Dr Since 26 Nov 2007

8. Looping point within restricted areas

Some routes loop within restricted areas where a pass is needed to enter. Such is the case for Changi Airfreight Terminal, where only workers with a valid entry pass can enter the restricted area. For card-paying passengers, their ride will be suspended upon tapping out at the Police Pass Office, and resumed upon boarding the same service as they alighted (at another bus stop near the Police Pass Office after buses exit the restricted areas). For cash paying passengers, they will have to pay again upon boaring if their ticket expires within the restricted area. (A→B→C→B→A)
