The Scania K310UD (K-Series 310-bhp Urban Double-deck) is a low-entry, wheelchair-accessible double-decker transit bus built by Scania AB. Commonly referred to as the “KUD”, the chassis is manufactured in Europe, and the bodywork supplied by Gemilang Coachworks of Malaysia.
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. Many other Scania double-deck buses in Singapore are owned by private operators and configured as open-top sightseeing buses.
The Scania K-series is the successor of the Scania L-series and the Scania 4-series. 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 470hp, depending on the chassis variant (e.g. the 230hp engine is only available with the KUB).
Unique features of the Scania K-series is the longitudinally, straight-up mounted, inline-cylinder engine located at the rear. The K-series is available with the 9-litre 5-cylinder engine or the 12-litre 6-cylinder engine. Both engine types use Exhaust Gas Re-circulation (EGR) technology to achieve the Euro IV rating. Euro V-rated engines feature both a larger bore and a longer stroke.
SBS Transit K310UD demonstrator (SBS7888K)
Following the successful large intake of the Scania K230UB, SBS Transit acquired a Scania K310UD for demonstration purposes. It was registered as SBS7888K on 26 Mar 2010, during which the Euro V Batch 2 Scania K230UBs were being registered.

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.
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. From 2011 to 2016, it was deployed on Service 25. After several months of rotating around Service 168 and 72/72B, it was redeployed 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.
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 covered in a special advertising wrap in celebration of Scania’s 100th anniversary. The bus later returned to Singapore and continued revenue service on Service 25.
