The Mercedes-Benz Citaro (or O530) is a low-floor, wheelchair-accessible, single-decker transit bus built by Mercedes-Benz and EvoBus GmbH. It is the successor to the older O405/O405N series, and is popular around the world, with over 40,000 units built since 1997. Commonly referred to as simply the “Citaro”, they are manufactured in Germany and shipped completely built-up (CBU) to Singapore.

First introduced locally in 2010 by SMRT Buses, the company ordered a small batch of buses which were delivered in 2011. SBS Transit followed suit, and made one of the largest Citaro orders to date, ordering around 1000 buses with deliveries from 2011 – 2016 and later further expanded by the Land Transport Authority (LTA).

In 2016, under the Bus Contracting Model, the LTA leased Mercedes-Benz Citaro buses (built to SBS Transit specifications) to Tower Transit, Go-Ahead Singapore as well as SMRT Buses.

With the exception of a handful of SMRT Citaros, most Citaros in Singapore are similar in technical specifications, with differences only in the interior specifications. In Europe, these would be referred to as ‘face-lifted Citaros’ (Year 2005) to differentiate them from the first generation of Citaros, which were produced since 1997.

Technical Data:

The Mercedes-Benz Citaro line of buses come in a number of variants across urban and suburban configurations. The urban model is available as rigid bus is available with two or three axles, and as an articulated bus with three or four axles. The rigid bus also comes in two-door and three-door options, and the articulated bus ranging from three-door to five-door options. The fully low floor design is attributed to its small rear, side-mounted engine which allows for smoother passenger entry and exit.

All Citaros in Singapore are of the 2nd-generation 12-metre urban model with two doors. They fulfill the requirements of the Euro 5 and EEV emissions standards using BlueTec 5, the selective catalytic reduction (SCR) technology developed by Mercedes-Benz, hence requiring the use of AdBlue as a diesel additive.

It is worth noting that all Citaros are of the 2005-facelifted version, although Mercedes-Benz had launched a newer 3rd-Generation facelift in 2011. The older design was acquired in bulk likely as a cost-saving measure and to promote fleet standardization. As a result, Mercedes-Benz kept the production line for these 2005-facelifted buses open simply for the Singapore market.

As with thousands of other units around the world, the whole Citaro bus is completely built up by EvoBus, from its monocoque structure to its interior features, then shipped as a completed bus to Singapore. Local Citaros are produced in Mannheim, Germany.

Overview of Singapore Operations

SMRT Buses brought in the first Citaro into Singapore for demonstration purposes. A Year 2005 face-lifted Citaro, it was registered as SMB136C, and entered service in March 2010, prided as ‘Southeast Asia’s 1st 100% Low Floor Euro V Bus”. The bus was a well-conceived continuation of SMRT’s legacy with Mercedes-Benz buses, following its long history of operating O405s and O405Gs. Positive public feedback paved the way for more Citaros in Singapore.

By 2011, the exemption of Additional Registration Fee (ARF) for public buses made importing the foreign-built Citaros much more affordable. SMRT acquired 10 units in its first production batch in early 2011, followed by an additional 40 more units by late 2011, bringing a total of 51 units.

SBS Transit had put its confidence behind the Citaro with a first batch of 300 Citaros intended for fleet replacement and expansion, among the largest orders at the time. Technical specifications were highly similar to SMRT’s Citaros, and buses were delivered between 2011 and 2012. A further order of 450 additional Citaros are currently under delivery, expected to be completed by 2015. In July 2014, SBS Transit placed an additional further order of 250 Citaros, bringing the total to 1000 units.

In December 2015, the LTA bought out SBS Transit’s contract for any remaining Citaros yet to be delivered. Together with the BSEP fleet, these buses have been gradually reassigned to other bus operators as part of the Bus Contracting Model (GCM/BCM) under a lease agreement. A messy reassignment scheme is under way to transfer these buses from SBS Transit to their new operators. As a result, Tower Transit, Go-Ahead Singapore as well as SMRT Buses have Mercedes-Benz Citaros in their fleet, that were built to SBS Transit specifications.


SMRT Mercedes-Benz Citaro [Overview]:

SMRT brought in a single Demonstrator Unit and 50 Production Batch Mercedes-Benz Citaros (in two batches) between 2010 and 2011. These buses were built in Germany and shipped to Singapore as a whole. Formerly allocated to all bus depots, their limited numbers within the SMRT fleet led to these buses being eventually consolidated into Ang Mo Kio Bus Depot.

Many Citaro buses share similar technical specifications. Here’s a table at a glance:

After SMRT Buses brought in its first batch of wheelchair-accessible Mercedes-Benz OC500LEs in 2008-2009, there was a need to expand the bus fleet with more wheelchair-accessible buses to further cater to passenger demands. For Mercedes-Benz, the Citaro was the direct successor to the O405 series of buses, which SMRT operated in large numbers (along with the articulated O405G variant). The fully low-floor design, ride comfort and environmentally friendly technology was promising, and SMRT decided to bring in one unit for trial purposes.

Registered as SMB136C, the bus was unveiled on 9 March 2010 at a launch ceremony in SMRT’s Ang Mo Kio Bus Depot, exactly one day after its date of registration. Along with a promotional livery, it was marketed as “Southeast Asia’s 1st 100% low-floor Euro V bus”.

SMB136C entered revenue service exactly a week later, appearing on SMRT Service 855 on 16 March 2010. It was placed under a one-year trial on various trunk and feeder routes that was ultimately successful, with much positive feedback from passengers.

SMB136C has a licensed carrying capacity of 88 passengers, comprising 37 seating passengers and 51 standing passengers. The wheelchair bay accommodates a single wheelchair, and is equipped with a rear-facing foldable seat for two people when not occupied by a wheelchair user. Its interior layout would be duplicated in all future SMRT Citaro orders.

By end 2015, SMRT finally removed the promotional advertisement off SMB136C, which had been in bad shape after being stuck on for over five years. The bus appeared on revenue service in full SMRT livery for the first time in December 2015. The SMRT logo was replaced with a full-red version shortly afterwards.

SMRT Production Batch 1: SMB139U – SMB148T

Following the successful trial of SMB136C, SMRT Buses purchased 10 Mercedes-Benz Citaros as part of it’s fleet renewal programme. This was spurred by LTA granting public buses an exemption from the Additional Registration Fee (ARF), making importing the Citaros significantly more affordable. The buses were registered as SMB139U – SMB148T between 11 Mar 2011 and 6 May 2011.

This batch of buses retain the major technical specifications of SMB136C, with minor changes such as a newer-generation ZF Ecolife gearbox (SMB148T being the exception, being fitted with a Voith).

Additional Specifications:

Production batch Citaros use LAWO BENEFIT electronic display signages, with an upgraded nearside display to show route details along with the service number. SMRT’s Passenger Information System (PIS) is integrated into the interior, replacing the bus stopping indicator.

The original hopper windows (with little use in a tropical country) on SMB136C were changed for full-sized windows. The rear door has been changed to a out-swinging plug door, with an additional visual indicator that lights up when the doors are closing.

On the interior, the seat covers have also been changed to a blue and purple theme, with priority seats in red. similar to those used in the OC500LE, and priority seats with red seat covers. The PVC seat covers are easier to maintain compared to SMB136C’s fabric seats. On 21 March 2011, these production batch buses began their debut on services 75, 531, 920 and RWS8 Staff.

SMRT Batch 1 Citaros have licensed carrying capacity of 88 passengers, comprising 37 seating passengers and 51 standing passengers. The wheelchair bay accommodates a single wheelchair, and is equipped with a rear-facing foldable seat for two people when not occupied by a wheelchair user.

As SMRT Buses’ New Livery was rolled out, SMB140P received a new corporate livery.

SMB148T: The Unofficial SBS Transit Citaro Prototype

SMB148T was part of the Batch 1 Citaros, but was only registered in May 2011 (while 139 – 147 were registered in March 2011). The bus was delivered with a four-speed Voith DIWA 854.5, different from its ZF EcoLife 6AP 1200B cousins in Batch 1. After delivery, it was retained with Mercedes-Benz’s local dealer, Jardine Cycle & Carriage (C&C) for two months where it was fitted with a mock-up interior for SBS Transit for trialing purposes. It was later re-assembled with SMRT interior configuration, registered and handed over to SMRT in May 2011, making its debut on Premium 531.

The interior fixtures are similar to its Batch 1 cousins, and its most distinguishing feature is the Mercedes-Benz badge at the front of the bus, which was not filled up in black.

SMRT Production Batch 2: SMB149R – SMB188C

Following up on the first production batch of 10 buses, a second batch of 40 SMRT Mercedes-Benz Citaros were registered between 7 Oct 2011 and 30 Nov 2011, in numerical order (SMB149R – SMB188C).

The Production Batch 2 citaros would be fitted with a 4-speed Voith DIWA 854.5 gearbox (similarly installed on SMB148T and future SBS Transit orders), in place of the six-speed ZF Ecolife gearbox.

SBS Transit Mercedes-Benz Citaro [Overview]:

While SMB136C was still under trial by SMRT Buses, SBS Transit announced its purchase of 300 face-lifted Citaros (similar in appearance to SMRT’s Production Batch) to replace its retiring Volvo B10M Mk IIIs. This was the largest Asian order of Citaros to date. These initial 300 buses under Batch 1 were procured at a cost of $110 million and were registered between April 2011 and August 2012.

With the success of the first batch of Citaros, a follow-up order of 450 Mercedes-Benz Citaros was announced as part of its fleet renewal programme. Buses in Batch 2 were registered from January 2013 to April 2015.

In July 2014, a further order of 250 Citaro buses was placed, with deliveries starting from Apr 2015 to 2016, but midway through deliveries, the LTA bought out SBS Transit’s contract for any remaining Citaros yet to be delivered. Together with the BSEP fleet, these buses have been gradually reassigned to other bus operators as part of the Bus Contracting Model (GCM/BCM) under a lease agreement. More buses were ordered by LTA as well.

Breakdown of orders is as such:

  Production Batch Purchased under BSEP or GCM Year
Batch 1 SBS6000L – SBS6285G with gaps in registration numbers
(258 units)
SBS6300X – SBS6341C
(42 units)
2011 – 2012
(300 units total)
Batch 2 SBS6600E – SBS6818U, SBS6822G – SBS6865H
(266 units)
SBS6342A – SBS6508P, SBS6530Z – SBS6549X
(208 units)
2013 – 2015
(450 units total)
Batch 3 SBS6819S – SBS6821J, SBS6866E – SBS6893B
(31 units)
SBS6509L – SBS6529D, SBS6546D – SBS6599B, SBS2000M – SBS2004C
(76 units)
GCM Units:
SG1000G – TBC, SG1691L – SG1699R
(TBC units)
2015–
(250 units with additional order from LTA)

Whilst all deliveries were ongoing, the Bus Service Enhancement Programme (BSEP) was gaining traction, and to support the expansion of the BSEP, some Citaro buses would be transferred over to Government ownership. These BSEP-registered units are purchased by the Government, as funded by the BSEP budget. In 2015, to support the gradual implementation of the Government Contracting Model (GCM), Citaro buses were procured by tapping into SBS Transit’s existing orders, and will thereafter be leased out to successful tenders of the various route packages. Early batches of these buses were registered immediately with the SG-prefixed registration plates without having to be registered with a SBS-prefix registration plate.

It is worth noting that SBS Transit’s Citaros are of the 2005-facelifted version, although Mercedes-Benz had launched a newer facelifted version in 2011. The older design was acquired in bulk likely as a cost-saving measure and to promote fleet standardization.

Many Citaro buses share similar technical specifications. Here’s a table at a glance:

SBS Transit Production Batch

SBS Transit Batch 1:

SBS Transit’s first batch of Citaros were registered between April 2011 and August 2012, intended to replace their retiring Volvo B10M MkIIIs. 300 2005-facelifted Citaros were ordered a cost of $110 million, which was then the largest Asian order of Citaros to date. Technical specifications of the new batch are very similar to those in SMRT’s production batch, with the only differences being interior configuration and the high density LAWO HIGHLED electronic display signage.

A total of 300 buses fall under the Batch 1. 258 units, namely SBS6000L SBS6285G (with unused registration numbers in between), were registered to SBS Transit. Midway through deliveries and registration, 42 units of this batch were reallocated to the then-newly-launched Bus Service Enhancement Programme (BSEP), for deployment on new BSEP routes, as well as the service enhancement of existing routes. BSEP Buses were registered as SBS6300X SBS6341C. All buses were registered between 26 April 2011 to 3 December 2012.

The large order of Citaros was made possible with LTA’s exempting public transit buses from the Additional Registration Fee (ARF), enabling SBS Transit to acquire the Citaros at a much cheaper price and in bulk. A handover ceremony was organised on 16 May 2011 at SBS Transit’s Ang Mo Kio Depot with the first two SBS-registered Citaros, SBS6000L and SBS6001J. SBS6000J entered revenue service on 1 June 2011 on Service 28 between Tampines and Toa Payoh.

EDS LAWO HIGHLED
Additional Specifications:

On the outside, the most distinguishing feature is the LAWO Electronic Destination Signage (EDS) which appears more defined than SMRT’s Citaro EDSes. The LAWO HIGHLED used in SBS Transit Citaros are a much denser array of LEDs to display clearer text, and they are able to form images such as those used in Express and Fast-Forward routes. The swinging-plug exit door is same as those on SMRT’s production batch.

The seating configuration slightly differs from SMRT’s Production Batch of Citaros, with the exclusion of two seats and the foldable seat at the wheelchair bay, allowing for a larger standee area. The foldable seat is replaced with a simple backrest. Seats use PVC covers in SBS Transit’s colour scheme; yellow seats between the front and rear doors, and red seats for the rear half of the bus. A manual wheelchair ramp is fitted at the rear door as a standard specification.

The first few buses in this batch were equipped with a larger palm-type bus stopping bell pushes, but subsequent buses had reverted to the normal push-button-type bus stopping bell. The larger bus stopping bell could be easily triggered by leaning on it, causing frequent false indications to the driver, and these were eventually replaced with normal push-button-type bells.

From SBS6150L onwards, larger and more air-conditioning vents were installed to cope with tropical weather.

Finally, the bus stopping sign has been integrated into the design, similar to SMB136C, but instead just shows the word “STOPPING”.

SBS Transit Batch 1 Citaros have licensed carrying capacity of 90 passengers, comprising 35 seating passengers and 55 standing passengers. The wheelchair bay accommodates a single wheelchair.

SBS6103Z is fitted with a next stop reporting system (with audio) and electronic screens as part of a LTA-initiated trial. The bus is not on revenue service. More on this bus at this news article.

SBS Transit Batch 2:

With the success of the first batch of Citaros, SBS Transit decided to follow-up with a second batch of Citaros as part of its fleet renewal programme. 450 Mercedes-Benz Citaros and another 550 Volvo B9TL Wrights were added at a cost of $433 million SGD. Of the 1,000 new buses, 260 were funded by the Government under the Bus Services Enhancement Programme (BSEP), while SBS Transit will fund the 740 buses under its growth and fleet replacement plans.

A total of 450 buses fall under under the Batch 2. 263 units were registered to SBS Transit namely SBS6600E – SBS6818U, SBS6822G – SBS6865H. 187 units were allocated to the Bus Service Enhancement Programme (BSEP), registered as SBS6342A – SBS6508P, SBS6530Z – SBS6549X, for deployment on new BSEP routes, as well as the service enhancement of existing routes. All buses were registered between 2013 and 2015.

SBS Transit Batch 2 Citaros have licensed carrying capacity of 90 passengers, comprising 35 seating passengers and 55 standing passengers. The wheelchair bay accommodates a single wheelchair.

 

 

SBS Transit Batch 3:

In July 2014, SBS Transit announced orders worth S$311 million for 250 Mercedes-Benz Citaro buses and 415 Volvo B9TL Wright buses, a total of which 296 will be funded by the Government under the Bus Service Enhancement Programme (BSEP). These 250 Mercedes-Benz Citaros fall under the Batch 3, with deliveries starting in April 2015. However, in December 2015, the LTA bought out SBS Transit’s contract for any remaining buses yet to be delivered, transferring these buses to the Government Contracting Model (GCM).

The Batch 3 Mercedes-Benz Citaro were registered from 23 Apr 2015, using the registration numbers SBS6819S – SBS6821J, SBS6866E – SBS6893B for SBS Transit-owned buses, SBS6509L – SBS6529D, SBS6546D – SBS6599B, SBS2000M – SBS2004C for BSEP buses and SG1000G onwards for GCM buses.

Additional buses of unknown quantity were ordered by LTA ontop of SBS Transit’s order of 250 buses.

    (The first 23 batch 3 buses, batch 2 & 1 buses had a grey floor design on the raised part of the bus at the seating area after the exit door)
  • Leg safety panel directly after exit door and standee area changed from frosted glass to black glass.
  • Reduced height of exit door sensor

As announced in December 2015, the LTA will buy over 12 Citaros from SBS Transit to expand the GCM bus pool. These buses are SBS6882H to SBS6893B.

SBS Transit Batch 3 Citaros have licensed carrying capacity of 90 passengers, comprising 35 seating passengers and 55 standing passengers. The wheelchair bay accommodates a single wheelchair.


SBS Transit BSEP Batch

For background information on the BSEP, read the Bus Service Enhancement Programme article.

Before the Bus Contracting Model (BCM/GCM) was launched, the LTA had directly funded the purchase of buses under the Bus Service Enhancement Programme (BSEP) launched in 2012, where these resources were used to launch new bus routes and enhance existing ones. Whilst registrations for Batch 1, 2 and 3 Mercedes-Benz Citaro were ongoing, a portion of buses from each batch were diverted to the BSEP, where they were registered as SBS6300X – SBS6599B and SBS2000M – SBS2004C.

Technical specifications of the BSEP-registered Citaros are identical to the Production batches that they were taken out from.

  • Initial batch: SBS6300X – SBS6341C
    = Similar to Batch 1 specs
  • Second batch: SBS6342A – SBS6508P, SBS6530Z – SBS6549X
    = Similar to Batch 2 specs
  • Third batch: SBS6509L – SBS6529D, SBS6546D – SBS6599B, SBS2000M – SBS2004C
    = Similar to Batch 3 specs

Deliveries ended in early 2016 with the remainder of buses registered under the GCM instead. BSEP Mercedes-Benz Citaros were also the first buses to spearhead the transition to the GCM as these buses were owned by the Government.

Additional Specifications:

Under the BSEP, these buses are subject to strict deployment regulations, such as being barred from commercial advertising, and deployment only on BSEP bus routes or enhanced bus routes under the BSEP scheme. The LTA can track bus positioning, passenger loading statistics and other parameters in real time.


Transition to Government Contracting Model (GCM)

For a more detailed guide, please refer to this article.

As part of the GCM, LTA would purchase buses from both SBS Transit and SMRT Buses to lease them to the winning transport operators of the various route packages. The bus models for this scheme include SBS Transit’s Mercedes-Benz Citaros, SBS Transit’s Volvo B9TL Wrights, SMRT’s MAN A22s, SMRT’s Alexander Dennis Enviro500s as well as SMRT’s MAN A95s.

LTA has initiated the GCM initially using buses destined for SBS Transit but registered under the Bus Service Enhancement Programme (BSEP). These buses, destined for service with SBS Transit fleet but owned by the Government, were rerouted to operators of the first few GCM packages such as Tower Transit, the initial operator of the Bulim Bus Package. As such, several new Citaro buses built to SBS Transit (Third Batch) specifications would be registered from SG1000G onwards.

To further expand the GCM bus pool, the LTA said on 29 December 2015 that it would take over SBS Transit’s bus purchasing contracts worth S$164 million for 346 new bus purchases, scheduled for delivery in 2016 and 2017. It will also directly buy 50 buses, worth about S$23 million, which were delivered to SBST between June and December in 2015.

Among the 346 buses to be bought under the contracts, 100 are single-deck Citaro buses, and among the 50 buses to be bought from SBS Transit, 12 are single-deck Citaro buses. In total, LTA will be buying 112 Mercedes-Benz Citaro single-deck buses (SBS6882H – SBS6893B).

SBS Transit Specification Citaros for SMRT

On 11 Feb 2016, 9 Mercedes-Benz Citaro buses were registered as SG1691L SG1699R for SMRT Buses. These buses were originally to be registered SG1011A – SG1019D for Tower Transit under the Bulim Bus Package. However, for various reasons, they were passed on to be operated by SMRT Buses for the short term, possibly to offset smaller quantities of MAN A22 buses ordered under the BSEP. With insufficient MAN A22 BSEP buses, new BSEP bus services such as Service 805 were introduced running on non-BSEP buses.

SG1000G – 1000th Mercedes Benz Citaro Celebrations

To celebrate the delivery of the 1000th Citaro, SG1000G had a large “1000th Citaro Celebrations” text pasted across the windows, on both sides of the bus. First spotted in early March 2016, the bus was also programmed with a custom “1000th Citaro Bus In Singapore” Electronic Display Signage message used for an internal event.

When SG1001D was the first Citaro to be registered under the GCM, as compared to SG5000E being the first Volvo B9TL, we gather that SG1000G was likely reserved by the LTA for the 1000th Citaro delivered to Singapore.

The bus is currently operated by SBS Transit, sporting a early version of the Lush Green livery with a grey section at the front. The operator logo was added in early 2017.
