The bus bears resemblance to the Switch Metrocity, sharing similar interior and exterior features.

[1][2][3] The Metrodecker was launched by Optare in 2014 initially with the 4 cylinder Euro VI Mercedes-Benz OM934LA engine with a 6-speed ZF EcoLife transmission fitted.

[2] In June 2018, Reading Buses placed the first order for five diesel Metrodeckers with high specification interiors for use on Green Line route 702, following a period of demonstration.

The MetroDecker H2 is based on existing EV platform, utilising Arcola's A-Drive hydrogen fuel cell electric powertrain with a claimed range of up to 250 miles (400 km).

[22] An investigation into the Potters Bar fire found that a conductive coolant had inadvertently been added to the battery system of a Metrodecker EV instead of a non-conductive one, and the buses returned to service later that month.
