[3] The first example, built on a Volvo B9TL chassis for Delaine Buses, was displayed at Euro Bus Expo 2006.

The Olympus replaced the OmniDekka on Scania chassis (though was still sold alongside the bus until 2011), which is 10.6 or 11.9 metres in length.

At the beginning of January 2007, Reading Buses ordered six Olympus with Scania chassis for their Loddon Bridge FastTrack park and ride contract to replace Optare Excels.

Due to problems with the new Transport for London specified air-conditioning units, some buses failed the tilt test by one degree, and entered service late.

Reading Buses has numerous examples bodied by Darwen, in addition to a few built by East Lancs before they went into administration.
