Trans-Island Bus Services bought Mercedes-Benz O405 with Hispano Carrocera (both with and without air-con, although the latter was retrofitted with air-con later on) and Volgren CR221 bodies to replace the ageing Hino RK176, Nissan Diesel U31F and Hino HT228KA from 1994 to 1999. All Mercedes-Benz O405 with Hispano Carrocera bodywork had been retired by 25 September 2016. The Volgren-bodied O405s on the other hand were used as permanent training buses, only fully retiring by late February 2017. TIBS also procured various batches of bendy buses (Hispano Mark 1, Hispano Mark 2, Pininfarina-designed Hispano Habit and Volgren CR221) bodies between 1996 and 2004. All buses were retired on 1st December 2020, in line with LTA's directive of removing non-wheelchair accessible buses from revenue service.LTA official website Land Transport Authority
