Bus Contracting Model – Storage buses

Under the Bus Contracting Model (BCM) for Singapore’s public bus industry, the Land Transport Authority (LTA) owns all bus assets (such as buses, bus depots, bus interchanges/terminals, and so forth). As for buses, the LTA is also responsible for the renewal and replacement of these assets, and currently maintains a pool of spare buses that can be readily leased to bus operators when needed.

However, in recent years, a steady increase in excess buses (that have not been leased to any operators) has been observed. These vehicles are registered, yet remain garaged in bus depots and not in revenue service. Furthermore, time spent while in storage still counts towards the 17-year statutory lifespan for public buses. Hence, this article aims to shed some light on current practices.

These developments come on top of an unprecedented bus industry spending, with LTA posting a $1.013 billion deficit for the 2018/19 financial year.

Excess buses in depots

Under the BCM, bus operators pay LTA a fee to lease public buses. At the same time, operators have to meet service standards set out by the LTA, governing the frequency, operating hours and percentage of high capacity buses deployed on a route. These standards change over time as the LTA tweaks the level of service required.

As a result, bus operators have a financial incentive to optimize their operations and minimize the number of buses they lease from LTA. One way operators achieve this is through efficient scheduling of buses – for example, increased use of bus interlining (which schedules bus drivers on several different bus routes during a shift). This practice rose to notoriety when it was blamed for a spate of Bus Captain resignations in September 2016, but all bus operators engage in some form of this practice.

Bus depots functioning as excess bus storage

LTA Bus Storage at Seletar Bus Depot

Storage buses are typically parked at a corner of a bus depot (most prominently in Seletar Bus Depot). They are formally assigned to an operator (the lessee of the depot where the bus is parked) by means of vehicle registration, but the operator does not use these vehicles, nor does it pay LTA to lease these buses. It is understood that the upkeep of these storage buses is maintained by the said bus operator.

Some of these storage buses were registered and directly assigned to the storage fleet, without seeing a day of revenue service.

More recently, the LTA had laid-up buses in storage, likely to avoid having to pay road tax on these vehicles. It is unclear why this is practice is carried out, since all road tax revenue is returned to the Government. With or without the lay-up, buses in storage are still formally registered and thus count down towards their 17-year statutory lifespan even while sitting unused in storage. The current practice of mothballing registered buses is thus a wasteful use of a bus’ statutory lifespan.

Buses in storage:

MAN A95 (Euro 6) MAN A22 (Euro 6) Mercedes-Benz Citaro Volvo B9TL
Quantity (as of 1 Feb 2020) 7 30 3 1

Information Source: SGWiki

Since then, several buses were taken out of storage for replacement of retiring Volvo B10TL buses.

Excess buses incoming

Despite the many buses currently in storage, a large influx of new buses is expected in the near future. Unless there are plans for a drastic increase in bus service levels in the coming months or years, the glut of excess buses in storage (registered or otherwise) will continue to exist.

Currently, a total of 150 Euro 6 single-deck buses (MAN A22) and 250 Euro 6 double-deck buses (MAN A95) are in the midst of registration as part of a bus purchase in 2018. Registration of these new buses has been slow due to the introduction of 50 diesel hybrid buses (Volvo B5LH) and 60 electric buses (BYD K9 (Gemilang), ST Engineering Electric Bus, Yutong E12, Yutong E12DD) which are bring prioritized for introduction to revenue service.

In addition, the LTA has awarded tenders for more buses, namely 111 Euro 6 double-deck buses (MAN A95) awarded later in 2018, followed by a further 100 Three-Door Euro 6 Double Decker Buses scheduled to enter service in 2020. As of February 2020, neither of these buses have been sighted in Singapore.

As of 1 Feb 2020:

Euro 6 Single Deck – 1st Batch Euro 6 Double Deck – 1st Batch Euro 6 Diesel Hybrid Buses Euro 6 Double Deck – 2nd Batch Electric Buses 3-Door Double Deck buses
Quantity Registered (as of 1 Feb 2020) 109 / 150 234 / 250 50 / 50 0 / 111 14 / 60 0 / 100
Registration date May 2018 (ongoing) May 2018 (ongoing) Nov 2018 – Mar 2019 Expected: 2019 Jan 2020 (ongoing) Expected: 2020

One possible reason for the accelerated bus orders and deliveries can be traced to 2018. At the Committee of Supply Debate 2018, Transport Minister Khaw Boon Wan promised a significant 450 new buses to increase capacity on existing or new routes that run parallel to MRT lines whilst renewal works were ongoing.

To accelerate the renewal of the ageing assets, we will reinforce our bus network to provide some back-up capacity. We will be deploying 450 buses to bolster capacity along existing bus routes which support critical stretches of the rail network undergoing renewal. These are new buses. They were ordered to meet growing ridership demand and to replace our ageing bus fleet. We are opportunistically bringing forward their purchase and deployment to strengthen the resilience of our public transport network in the interim.

Some progress has been made towards delivering this promise, with the introduction of several Short Trip Services (2A, 7A, 7B), additional trips on their parent services, and a slew of full-day express bus services (12e, 147e, 167e851e and 960e) introduced since 2018. However, the number of new buses allocated to these new services fall far short of 450 buses, and rationalization of nearly all these routes have been carried out, with shorter operating hours for 7A, 7B, 12e, 147e851e & 960e, and the withdrawal of 147e.

Moving forward

Currently, in addition to storage buses being parked at Seletar Bus Depot, the remaining Euro 6 MAN buses that have yet to be registered (as part of the 2018 MAN Euro 6 bus order) are parked at PLG Logistics in Tuas South and ST Engineering Land Systems’ compound at Corporation Road, and it is not known how much costs are involved for the storage of these buses at private premises.

Under contractual obligations, LTA will likely continue to receive these new buses at a time when there is an excess of unused buses in Singapore, unless it works out a revised timeline to defer the delivery of these new vehicles. With LTA rationalising bus routes recently and cutting excess in a time of unprofitability, it remains to be seen if the LTA will continue to be holding on to large numbers of unregistered buses.

    LTA should venture a new bus park with minor facilities for future storage.Any operators wish to lease or return can directly go there instead of jamming up operational depot.350 capacity also enough.No need to store at ST or the Tuas logistic centre.
    Oh by the way we already got new BCM like Bulim,Loyang,Seletar,Ulu Pandan,Mandai and the upcoming Sengkang West,Kim Chuan,East Coast,Gali Batu & also Tengah.So is there any replacement for Bedok,Braddell/SBST Ang Mo Kio,Bukit Batok & Woodlands?

    All 7 A95 has been leased to SBST as for 13/02/2020.Even SG5039.

    Sgwiki made errors.
    No such thing as B4 A22 or A95.They are all Euro VI,Should be B1/B2

      They are part of MAN A95 and also SG2017C is part of an euro VI but why in the b3 huh? So it make sense if b4 MAN A22 AND MAN A95 are euro VI

      SG2017C was purchased under Batch 3 order hence the interior design and EDS are the same as all the other Batch 3 A95s
