Former SMRT MAN A22 buses purchased by Private Bus Operators

Several MAN A22 buses, formerly operated by SMRT Buses, have been sold to private bus operators in 2021.

These buses were formerly part of the COMET MAXI fleet, specifically retrofitted for use as COVID-19 patient transporters. Twenty such MAN A22 buses underwent conversion works.

In May 2020, twenty MAN A22 (Euro V) buses previously owned by SMRT Buses were converted into  COVID-19 patient transporters, branded COMET MAXIs. These buses first entered revenue service with SMRT in late 2011, but were re-registered as private buses after COMET MAXI conversion. Each bus seats around 34 patients. During their COMET MAXI stint, buses were owned by Sheares Healthcare and operated by Strides Transportation.

Interior modifications were made to enable the safe carriage of COVID-19 patients. These included an airtight floor-to-ceiling partition between the driver and passenger compartments, separate air-conditioning systems for both compartments, and the installation of a Negative Pressure System (NPS) with a HEPA filter in the passenger compartment that necessitated the removal of two window seats. All buses were also repainted to the COMET MAXI livery.

The 20 converted MAN A22 buses and their new registration numbers were:

  • SMB196D > PC8932C
  • SMB197B > PC9034M
  • SMB198Z > PC8997R
  • SMB200A > PC9271U
  • SMB201Y > PC9089E
  • SMB202U > PC9264R
  • SMB203S > PC9064B
  • SMB204P > PC9098D
  • SMB205L > PC8948H
  • SMB206J > PC9174S
  • SMB207G > PC8941B
  • SMB208D > PC9043L
  • SMB209B > PC9054E
  • SMB210X > PC9173U
  • SMB212R > PC9255S
  • SMB214K > PC9040U
  • SMB215H > PC9263T
  • SMB217C > PC8976B
  • SMB218A > PC9078L
  • SMB219Y > PC8969Y

COMET operations were scaled down massively sometime around August/September 2020 with the decline of COVID-19 cases in workers’ dormitories, and the fleet of buses sat largely disused until 2021.

Sold via motor dealer

Sometime in 2021, the ownership of 19 MAN A22 COMET MAXI buses (all except PC9040U) was transferred to Leons Automotive, a wholesaler of motor vehicles. In addition, all 19 units were laid up in late April 2021, one year after they were registered as private buses, possibly to avoid paying road tax on these unused vehicles.

Ownership was subsequently transferred to various Private Bus Operators after the sale of buses were completed.

Former Deployments
  • PC9040U – Operated by Cityline Travel till Q2 2021


Cityline Travel (PC9040U only)

PC9040U was formerly operated by Cityline Travel, and was the only COMET MAXI A22 to not have been laid up in April 2021.

As of late May 2021, the bus was last observed to be bearing the COMET MAXI livery and the Negative Pressure System (NPS). The ownership of the bus itself is presumed to be a motor financing or leasing company that purchased the bus from Sheares Healthcare, and is yet to be ascertained.

Additional seats (obtained from scrapped Volvo B9TL (CDGE) buses) were installed in the bus and the NPS was eventually removed.

Ownership of the bus was transferred to A&S Transit Pte Ltd in July 2021.

Leisure Frontier

Leisure Frontier shared in a 19 May 2021 Facebook post that it had taken over PC8969Y and repainted it into its company livery in white, orange, and red. It was taken out of layup and re-registered as PD7774T to Frontier Tours Pte Ltd in late May 2021, but the company of registration was changed to Leisure Frontier (S) Pte Ltd sometime afterwards.

Modifications were made to the bus to revert some of the COMET MAXI modifications:

  • Removed negative pressure system (NPS) and window privacy stickers
  • Removed emergency door between driver and passenger compartment – but the existing bulkhead is still fitted to the bus
  • Removed driver blower fan
  • Missing window seats (initially removed to facilitate the NPS installation) were reinstalled using seats obtained from scrapped Volvo B9TL (CDGE) buses

Another unit, PC9173U, was transferred to Frontier Express Pte Ltd in July 2021 and re-registered as PD8989J.

A & S Transportation

A & S Transportation shared a Facebook video on 28 May 2021 that promoted their ownership of a “CovidSafeBus” fleet of buses. The video shows six buses that were pasted with the A & S Transportation logo, which were PC8932C, PC9098D, PC9174S, PC8941B, PC9255S & PC9078L.

The buses appear to have retained all COMET MAXI modifications and were taken over by A & S Transportation in an as-is condition.

In late June 2021, the registration of 3 units was transferred to A&S Transit Pte Ltd.

  • PZ442G (Re-registered from PC8976B)
  • PZ842K (Re-registered from PC9043L)
  • PC8997R

In July 2021, PC9040U was transferred to A&S Transit Pte Ltd.

    They should have fit coach seats with headrest..I hope LTA will sell some Citaros to private operators as well.Ive seen those Private A22 exceed 60 on highways too.

      No need for coach seats, the existing design is already good enough for most people who will be boarding these buses for their shuttle.
