The Scania K310UD (K-Series 310-bhp Urban Double-deck) is a low-entry, three-axle bus chassis offered by Scania AB, intended for bodying as a double-deck bus. Also referred to as the ‘Scania KUD’ or simply ‘KUD’, it is one of many configurations offered by Scania’s K-series of bus chassis for city and intercity buses.

Currently, SBS Transit is the only public transport operator to own and operate the Scania K310UD in Singapore, with a single demonstrator unit to date. Several other Scania double-deck buses in Singapore are owned by private operators and configured as open-top sightseeing buses.

Technical Information:

Launched in 2006, the Scania K-, N- and F-series are the successors of the Scania L-series and the Scania 4-series. Scania’s K series of bus chassis, which are characterized by the same drivetrain layout: having a centrally-mounted engine and transmission unit oriented longitudinally behind the drive axle (rear axle).

Variants of this chassis are offered for coaches, intercity buses, or urban buses. These include the KUA (Urban Articulated), KUB (2-axle Urban Single deck), KUD (3-axle Urban Double deck), KIB (Intercity Bus) and the KEB (high-end coach). Engine options cover a range of horsepower ratings, from the lowest of 230hp, to the most powerful of 490hp, depending on the chassis variant and emission rating. When fitted with a lowered rigid front axle, the K-series can be bodied as a low-entry bus.

The Euro IV Scania K310UD demonstrator bus in Singapore is fitted with the DC9 engine rated at 310 horsepower (169 kW).

SBS Transit Scania K310UD demonstrator (SBS7888K)

Following Scania’s large success in supplying SBS Transit with Gemilang-bodied Scania K230UB single-deck buses (where 1,101 units were acquired), a double-deck bus based on the same K-series chassis platform was produced, and offered to SBS Transit for demonstration purposes.

The Scania K310UD demonstrator bus was registered on 26 March 2010 as SBS7888K, in the midst of Scania K230UB (Euro V Batch 2) registrations.

The Scania K310UD is in many ways technically similar to the Scania K230UB, both part of the Scania K-series, which SBS Transit previously ordered in very large numbers (1101 units). The bus was eventually kept by SBS Transit after its trial period, unlike other demonstrator buses which were sent away after operators decided not to purchase additional units.

The bodywork installed on SBS7888K was the first double-deck bodywork developed by Gemilang Coachworks. A similar bodywork design made its way to Scania K320UD buses delivered to bus operators Ritchies Transport (Auckland) in 2013, and Southlink (Adelaide) in 2015.

Similar to the K230UBs, the K310UD is a low-entry bus equipped with one wheelchair bay and a manual ramp. The bus made its revenue service debut on 15 May 2010, operating on the now-defunct Service 133M and later Service 133 after the route’s capacity downgrade to single-deck buses. From August 2010 to April 2016, it was deployed on Service 25. After a short stint on Service 168 (Apr 2016 – Jun 2016) and 72/72B (Jun 2016 – Sep 2016), it was redeployed to Hougang Bus Depot as a permanent Training Bus after the Full Transition of the Bus Industry to the Bus Contracting Model, which saw many non-standard demonstrator buses removed from revenue service.

In May 2019, SBS7888K was transferred to Ang Mo Kio Bus Depot, and continues to be relegated to training duties.

Additional Specifications:

SBS7888K has a licensed capacity of 132 passengers, inclusive of 55 upper deck seating, 28 lower deck seating, 49 passengers and one wheelchair.

In 2011, SBS7888K was briefly shipped to Bangkok and bore a special advertising wrap in celebration of Scania’s 100th anniversary. The bus later returned to Singapore and continued revenue service on Service 25.
