Early Retirement of Volvo B9TL (CDGE) and Scania K230UB buses (2022)

On 1 January 2022, SBS Transit (SBST) retired the bulk of its Volvo B9TL (CDGE) fleet, along with some Scania K230UB (Euro IV) buses.

These operational changes implemented by SBST are the result of a new Framework Agreement (or “FA”) announced by SBST and LTA in November 2021, in connection with the transition of the Downtown Line to the New Rail Financing Framework Version 2.

SBST had agreed to replace 241 of its own buses (comprising 144 double-decker buses and 97-single-deck buses) with newer government-owned buses, which are more environmentally friendly and cost-efficient to maintain.

Early Retirement Buses
Volvo B9TL (CDGE)

With the retirement of 144 Volvo B9TL (CDGE) buses from January 2022, there are only 20 buses left on revenue service, distributed among Ang Mo Kio Depot, Bedok North Depot, and Bukit Batok Bus Depot. A further two units remain allocated to Hougang Bus Depot for training duties (SBS7383A & SBS7385U).

Scania K230UB (Euro IV)

97 Scania K230UB (Euro IV) buses were taken off revenue service in January 2022, with the majority of them from Ulu Pandan Bus Depot.

Several of these buses were with SPAD Registration for cross-border bus services 160 & 170. With the retirement of these buses, several MAN A22 and Mercedes-Benz Citaro buses were prepared for SPAD Registration in April 2022.

Bus Scrapping

Similar to the previous batch of early retired Volvo B9TL (CDGE) buses, the retired buses will be sent for scrap at various scrapyards.

Reserved to RVS Global

20 of the retired Scania K230UB buses had a notice pasted on their windscreen which read “Reserved to RVS Global”. Some of these buses were spotted in Keppel in July 2022.

    bruh lta should actually give lta storage, Citaro hybrid and b8l BACK to sbs instead of taking buses from other operators

    • 4 February 2022 at 9:57 PM

      Citaro Hybrid C2 trial has ended and is currently laid up in Mercedes Benz HQ in Singapore not used while the Volvo B8L is returned to Volvo Buses. All this happened in 2020.

    Honestly, as per the principle of public buses deployed on the cross border bus services, it is always the cheapest model, since these bus services are going to another country.

    Therefore, it is highly likely that 170 and 160, or whatever is the cross border public bus service that will go to Malaysia when the public buses can once again go to Malaysia, will use the cheapest model, which is the MAN A22 Euro V (Batch 3).

    Although now 170 and 160 have the Mercedes-Benz Citaro running on them, nonetheless, that is because right now they are only running in Singapore. If they resume the travelling to Malaysia in the future, I’m pretty sure the fleet will change to MAN A22 Euro V (Batch 3).

    Really hate how everything is nowadays. Miss the 90s n early 2000s.

      Totally agree with you. Bus redeployments have been very messy since LTA took over the planning. Painting these CDGEs with Lush Green and retrofitting them; and then retiring them early is really of waste of taxpayers’ money.

    Why were the CDGE B9TLs repainted while the €5 KUBs weren’t?

    • 20 January 2022 at 8:32 PM

      I honestly dont know why CDGES are repainted green while kubs are not considering CDGES are still SBS property. Anyways i suspect the E5 Kubs are in for early retirement as well. Their lifespan of 17 years end on 2027 but if they were retire early as well, probably 2025. Another factor to consider is the e5 kubs are only operated by SBS, lta probably plans to standardise the bus model and fleet in all 4 bus company eventually. Dont be surprise too, lta is more in favour of electric/hybrid buses, so this early retirement might be apply to the current diesel buses. This is probably lta plan to phased out the remaining diesel buses and bring in those newer electric or hybrid buses sooner. To summarise, likely E5 kubs will not be repainted and also will be due for early retire

      • 21 January 2022 at 1:52 PM

        Thing is some OC500LEs were turned over to TTS. Pretty sure it is possible that some €5 KUBs from HGDEP might have gone over to GAS if Hougang package was farmed out to them this year.

    Very sad to see all this buses go. All of them were good work horses. Will miss them greatly.
