 Due to the limited demand for older double deck coaches and the high seating capacity on the upper deck, many double-deck Metroliner DR130s were converted to open-top buses by Ensignbus, for use on their London Pride Sightseeing operation, latterly passing to The Original Tour.A total of 172 Metroliners were built, in four different variants.Only 21 of the original style of single deck Metroliner were built in 1983-84, 15 for NBC (East Kent and Eastern National), 4 for SBG (Eastern Scottish and Northern Scottish) and 2 for Strathclyde PTE.
