were exported to Trinidad and Tobago for use by the National Bus Company. Nederlandse Spoorwegen in the Netherlands purchased 25 on behalf of their bus subsidiaries NZH, Westnederland, Centraal Nederland and Zuidooster. Problems with windscreen glare resulted in the windscreens being removed and a different version being fitted. In France, Dijon purchased six, while St Étienne Municipality purchased 20. Singapore Bus Services received a single 11.6 metres (38 ft) dual door Leyland National 2 in February 1981 which would mostly work on bus route 143 as SBS6820L until its withdrawal in 1983, after which it was exported to Australia. In Australia, ACTION purchased 70 Nationals in 1974–75, 16 being fully assembled in England and 54 in Australia. Some were repowered with MAN engines. In 1975, Brisbane City Council purchased seven while the Melbourne & Metropolitan Tramways Board purchased 30. The Metropolitan Transport Trust purchased 63 in 1975–76 for use in Hobart. These were all 10.3 metre (33 ft 9 in") units, however one was rejected and its replacement was a 10.9 metre (35 ft 9 in) unit. Surfside Buslines were the largest Australian private bus operator with a fleet of 38 purchased new and second-hand. The chassis of the Leyland National was also sold as the Leyland B21 in limited numbers to overseas operators. Replacement In all over 7,000 Leyland Nationals were built. It was replaced by the Leyland Lynx. Survivors As a result of legislation preventing the use of step-entrance buses on normal public bus routes, no Nationals remain in service, the last major operator was Chase Bus Services, Chasetown who sold the operations to Arriva Midlands and ceased operating as a separate entity on 28 April 2007. Notably all but two retained Leyland 510 engines to the end. One Leyland National was converted by the Manx Department of Education and Children to act as a mobile IT classroom. The Manx Telecomputer Bus was in operation from 1998 to 2020. Over 100 Leyland Nationals have been preserved. The Workington factory has closed, though part of the building now forms part of a Stobart Group depot. Among these is the very first Leyland National for Midland Red, 101 (HHA 101L) which, preservation by First Midland Red, has recently been purchased by The Green Bus Company for further preservation. Articulated bus derivative In 1980, some underfloor-engined articulated buses with bodywork derived from the Leyland National were assembled by Charles H Roe.
