Portugal Double-decker buses were introduced in Portugal during the 1950s when buses in general started to be used in the main cities such as Lisbon, Porto, Coimbra and Setúbal. The types used were the AEC Regent and later the Daimler Fleetline and the Leyland Atlantean, with Portuguese-built bodies. There was also one Leyland Olympian as a demonstration vehicle in Lisbon. In Porto, there were double-decker trolleybuses, produced by Lancia and with Dalfa bodywork, in use from the mid-1960s until the mid-1990s. Double-decker buses were not in widespread use for normal service but were mainly used for sightseeing purposes. They were most commonly Portuguese-produced vehicles, including rebodies of regular service buses (for example, the Volvo B10R from Carristur), as well as some from former companies, such as the MAN SD202 from BVG Berlin, many of them still in circulation. The absence of double-decker buses on regular service lasted until 2011, when STCP acquired 15 double-decker buses, of the type MAN A39 (as used in Berlin). They were introduced at an event by the company, named "Duplex Tour", on 26 February 2011 and put into normal service on the 28th of that month. These buses can be seen usually on route 500. Russia Until 2011 double-decker buses were operating in the city of Barnaul. The double-decker fleet consisted of seven MAN SD200 and MAN SD202 second hand buses imported from Berlin. Those buses were used on routes 3, 10 and 17. In the mid-1990s, some double-deckers were operated briefly in Saint Petersburg. Spain Double-decker buses were introduced in 2014 in Bilbao by the city bus operator Bilbobus. They are not the first double deck vehicles in the city as ex-London Transport Q1 trolleybuses were sold to Bilbao after the end of London trolleybus operations in 1962 and were operated until the system's closure in 1978. Initially, six vehicles are operating on Bilbobus route 56. They have a capacity of 132 passengers - 80 seated and fifty standing. Sweden Sweden bought in 1965 50 Leyland Atlantean double-decker buses with Park Royal bodies. Leyland claimed they were the first double-decker buses with one man operation. They had two staircases and two pairs of doors. The Atlanteans were not replaced at the end of their revenue service life in 1974. Recently, however, in 2011 double-deckers returned to Sweden on revenue duties with VDL Synergy on in the
