The Volvo Olympian 2-Axle are the last non-air conditioned buses to be brought in by Singapore Bus Services and also the last non air-conditioned buses in Singapore. Due to the additional weight of the air-compressor which necessitated a third axle, they were unable to be retrofitted with air-conditioning. In late 2003, most of these buses were redeployed to industrial routes to replace the then outgoing Leyland Olympian 2-Axles. Half of this batch had their lifespan extended by 2 years due to insufficient deliveries of new buses. All units were retired between June 2011 and September 2013, and the non-airconditioned bus fare structure was abolished shortly after.
