In 1998, SBS ordered the last batch of 70 Volvo Olympian 3-Axle with Walter Alexander Royale bodywork, which were delivered with the standee area pre-installed. Registered between March 1999 and December 2000, all units were retrofitted with LECIP electronic destination signages (EDS) in the early 2010s. Unlike the earlier batches, none of these buses received a lifespan extension of 2 years owing to a large influx of replacements. All units of this batch were retired between March 2016 and December 2017.
