Ang Mo Kio Bus Depot: A Look Back

The SMRT Ang Mo Kio Bus Depot, a significant landmark within Singapore's public transport infrastructure, once played a pivotal role in supporting bus operations across various parts of the island. Located in the Yio Chu Kang industrial area, this facility was instrumental in the daily running of bus services for communities in Yio Chu Kang, Yishun, Sembawang, Woodlands, and even extending to areas like Lorong 1 Geylang and further east. Although its operational days have concluded with its demolition in 2022, understanding its history provides valuable insight into the evolution of bus services in Singapore.

Origins and Early Operations

The story of the Ang Mo Kio Bus Depot is intrinsically linked with the establishment of Trans-Island Bus Service (TIBS). Founded on 31 May 1982, TIBS emerged in response to the government's initiative to foster healthy competition within the public bus industry, aiming to rival the Singapore Bus Service (SBS) on a more equal footing. Upon commencing passenger service in April 1983, TIBS initially operated from a temporary depot. This early setup in Ang Mo Kio featured double-deck container offices and relied on makeshift sheds for bus repairs and maintenance. Diesel was supplied from skid tanks, and bus washing was a manual process. The construction of a more permanent facility, the Ang Mo Kio Bus Depot, was a significant step forward. Partially completed in 1985, TIBS moved into the new depot that same year, with its official opening taking place on 3 April 1986. The complex, built at an approximate cost of S$6 million, was designed to house administrative, engineering, and workshop facilities for TIBS and its sister company, Singapore Shuttle Bus (SSB). It also boasted essential amenities such as a refuelling station and an automated bus-washing machine.

SMRT Era and Facility Details

Following the integration of TIBS into SMRT Buses in 2004, the Ang Mo Kio Bus Depot continued its operations under new ownership. It's important to distinguish this facility from SBS Transit’s Ang Mo Kio Depot to avoid confusion. The depot, commonly abbreviated as AMDEP, was situated on a plot of approximately 2 hectares along Ang Mo Kio Street 64, within the Yio Chu Kang industrial estate. For much of its operational life, it served as the primary hub for bus routes in the northern and eastern regions of Singapore. Beyond its core function of supporting bus services, the depot also served as the former headquarters for both SMRT Buses and its predecessor, TIBS. The premises were equipped with a multi-storey administration building that included a staff canteen, crucial bus refuelling and washing facilities, extensive bus parking areas, and a vehicle workshop for routine maintenance. More significant repair work was typically undertaken at the Woodlands Depot. Access to the depot was facilitated by a combined vehicular entrance and exit leading to Ang Mo Kio Street 64. While the official address was Ang Mo Kio Street 62, this entrance was largely retained for emergency access only.

Operational Capacity and Adaptations

The bus park at Ang Mo Kio Depot was relatively compact. This constraint often led SMRT to utilise nearby bus interchanges, such as Yishun, for the overnight parking of buses. To accommodate the introduction of double-decker buses around 2014, the shelters above the bus parking lots were elevated, demonstrating the depot's adaptability to evolving fleet requirements. In addition to its bus operations, the depot also housed a commercial vehicle workshop managed by its subsidiary, SMRT Automotive Services (formerly TIBS Motors Pte Ltd), established in 1990. This workshop extended its services to SMRT Taxis (formerly TIBS Taxis) and a variety of other commercial vehicles, showcasing a diversified operational scope.

Transition and Closure

The landscape of bus operations in Singapore began to shift with the implementation of the Bus Contracting Model (BCM) starting in 2016. Under this model, newer bus depots are government-owned and leased to operators who secure contracts for specific bus packages. In the case of the Ang Mo Kio Bus Depot, its operational relevance diminished as its primary bus routes in Yishun and Sembawang were integrated into the Seletar and Sembawang-Yishun bus packages. These packages were awarded to SBS Transit and Tower Transit, respectively, and were based out of newly constructed depots in Seletar and Mandai. The Seletar package commenced in March 2018, followed by the Sembawang-Yishun package in September 2021. This transition left SMRT Buses with a reduced operational scale that no longer justified the continued operation of the Ang Mo Kio Depot. The final bus route managed by the depot, Bus Service 110, was transferred to Woodlands Depot in early September 2021. By the end of September 2021, all day-to-day bus operations ceased at Ang Mo Kio Depot. Following this, the facility was utilised for the garaging of several Land Transport Authority (LTA) storage buses and continued to be used by its commercial vehicle repair arm, SMRT Automotive Services.

The Demolition Phase

Indications of the depot's impending closure and demolition became apparent when SMRT published an Expression of Interest for tender QX021-025 in September 2021. This tender outlined plans for “Proposed office fitting-out works at Woodlands Bus Depot and demolition and reinstatement works at Ang Mo Kio Bus Depot,” signalling the end of an era for the facility. In February 2022, the depot was officially closed, with the remaining buses garaged there being transferred to LTA Storage at Bulim Bus Depot. Concurrently, the corporate headquarters of SMRT Buses Ltd relocated from the Ang Mo Kio Depot to SMRT’s main headquarters at Paya Lebar Quarter. The complete demolition of the Ang Mo Kio Bus Depot took place in 2022, marking the physical end of this former operational hub.

Notable Incidents

Throughout its operational history, the Ang Mo Kio Bus Depot was the site of a few notable incidents that garnered media attention. On 5 March 1999, two technicians sustained serious injuries in an explosion at the depot, an event reported in the newspapers the following day. More recently, on 6 June 2021, a tragic accident occurred when an SMRT technician lost his life, and a co-worker was injured. The incident involved a BYD C6 bus (understood to be PC8561P) falling onto them while they were working underneath it, after one of the two car jacks supporting the bus failed.

Fleet Composition (Prior to Package Transfer)

Before the commencement of the Sembawang-Yishun Bus Package by Tower Transit, the Ang Mo Kio Depot was home to a diverse fleet of buses, typically comprising:

• Single Deck Buses
• Articulated Buses
• Double Decker Buses

The specific models housed within the depot would have varied over the years, reflecting SMRT's fleet upgrades and operational needs.

Comparative Look: Ang Mo Kio Depot vs. Modern Depots

To appreciate the evolution of bus depot infrastructure, it's useful to compare the Ang Mo Kio Bus Depot with modern facilities. While AMDEP was a functional and important site, its ~2-hectare footprint and reliance on external facilities for major repairs highlight the advancements in current bus depot design and capabilities.
