Short-Trip Services
Short-Trip services, previously referred to as Shortworking Trip Services (SWTs), are short haul supplementary trips which ply segments of their parent route rather than the full route of their parent service. Due to the lengthy nature of most bus routes, Short-Trip services are needed to cater to specialised sectors, rather than improving bus frequencies throughout the route. This helps to better allocate resources to where they are needed.
Most Short-Trip services cater to sectors of bus routes encountering high demand, for example, between transport nodes and high-activity areas (e.g. between MRT stations and housing estates , industrial areas or educational institutions). These Short-Trip services operate during the weekday peak hours. Other Short-Trip services operate late at night, after the last bus of their parent service has departed. These services usually cater to residential sectors of long trunk routes. Finally, there are Short-Trip services that only operate on weekends and special occasions, catering to unique sectors of route encountering high demand.
Short-Trip services can be identified by adding an alphabetical suffix at the end of its parent service. The letters A, B and C are the most common, while other suffixes (like W) are less common. The suffix M is usually reserved for Route variants and not for Short-Trip services. However, not all A and B suffixed routes are Short-Trip services; exceptions include 502A, 518A, 700A, 859A/859B and 900A.

Currently, Short-Trip services can be divided into five broad categories based on their operating hours:
- Weekdays AM Peak Short-Trip services
- Weekdays PM Peak Short-Trip services
- Weekends, Public Holidays and Special Short-Trip services
- “Last bus” Short-Trip services
- Daily “Full Day” Short-Trip services
This list is not exhaustive and some Short-Trip services can fall into multiple categories. For detailed operating hours, refer to the bus service articles of their parent services.

This list does not include bus services that use the ‘T’ suffix to denote a terminating trip (36T, 291T, 293T, 358T, 359T, 811T, 812T, 911T & 913T).
In the past, prior to the Bus Contracting Model, bus operators (SBS Transit and SMRT Buses) withdraw Short-Trip services when they are no longer needed. Usually, there are no press releases and the service will cease to operate. Information regarding the Short-Trip service will be removed from company websites and from en route bus stops.
On rare occasions, ‘withdrawn’ Short-Trip services (which actually slip into oblivion) may make a comeback. Such was the case of SBS Transit Bus Service 159A which disappeared in the early 2000s, only to reappear in 2009.
