Mercedes-Benz OC500LE

梅斯特斯平治OC500LE (顺丰)
The history of OC500LE in Singapore began on 8 May 2004, when TransPerth TP1854 was brought to Singapore for an one-day evaluation in the Orchard shopping district. A Mark IV CNG model, the public was invited to ride on this bus for a round sightseeing trip (and for the two public operators to evaulate the bus). This bus was then returned to its original owner for continued revenue service. Little was heard after that, and for quite a while it was a subject of envy and hope by bus fans - that the OC500LE would one day return for revenue service in Singapore.

Four years later, the dream became a reality when SMRT Buses chose the OC500LE as its first fleet purchase under the re-branded company. Its demonstrator unit had the honour of being number 1 in the new registration prefix and was paraded as the first Euro V bus in South-East Asia and under the 'SMRT is Green' campaign. 66 more units were initially purchased, known to bus-fans as Batch One.

The OC500LE was the first wheelchair-accessible bus (WAB) introduced by SMRT Buses. It features the improved OM 457 hLA engine with the ZF6HP592C EcoMat six-gear automatic. To meet the stringent emission standards, the Selective Catalytic Reduction (SCR) with AdBlue was chosen for exhaust treatment. The LAWO SICMA-Flex EDS (orange colour) is LED-based and now standard within the industry, replacing previous flip-dot models. And Konvekta air-con unit was installed in all units.

Subsequently, SMRT Buses was satisfied with OC500LE's performance, and made a further purchase of 67 units. These Batch Two buses were introduced in July 2009, with a few slight changes made to its interior, bringing the total fleet to 134 buses. All units were assembled by the Thailand-based Thonburi Busbody, with the bodywork supplied by Gemilang.

Unfortunately in December 2009 TP1854 was destroyed by fire in Perth, Australia while on revenue service. (http://www.youtube.com/watch?v=NMW7e0YiCuY) Nobody was injured in the incident. In January 2010, SBS Transit declined the purchase of OC500LEs and returned its own demonstrator unit that it had evaluated for months to the dealer Cycle and Carriage. This unit subsequently went to private operator Chitson Transport.
