In the late 1970s in Ireland, Córas Iompair Éireann (now Bus Éireann and Dublin Bus) commissioned a range of single and double decker buses to be designed and produced. The prototypes were devised in Germany and production was carried out in Shannon, Co. Clare, Ireland. A total of 51 express coaches (KE type) and 366 double deck buses (KD) were assembled at this facility between 1980 and 1983. They remained in service until 1997 and 2000 respectively. Some surviving examples are now exhibits at the National Transport Museum of Ireland in Howth, Co. Dublin.
