Trolleybuses in Glasgow

The Glasgow trolleybus system operated in the City of Glasgow, Scotland, between 1949 and 1967, with the network reaching its largest extent in 1959. It was the only British system to open after World War II.
The trolleybuses were owned and operated by Glasgow Corporation's Transport Department (along with the city's buses, trams and the Subway).
Routes.
All Glasgow's trolleybus routes were numbered from 101 onwards. Summary of services:
Vehicles.
The majority of Glasgow's trolleybuses were double-deck vehicles, painted in Glasgow Corporation's orange, green and cream livery (though in a different style from the buses and trams). The destination blinds on the trolleybuses used white letters on a green background (unlike the trams and buses, with more conventional white lettering on a black background).
Glasgow's first trolleybuses were a fleet of 34 three axle (six-wheeled), double-deck B.U.T. vehicles with bodywork by Metro-Cammell of Birmingham. They were almost identical to those built for London Transport, even briefly including London's distinctive trolleybus symbol (a "T" over the London Transport roundel). In 1950 Glasgow bought 30 Daimler trolleybuses.
Between 1957 and 1959, a fleet of 90 B.U.T. type 9613T trolleybuses with Crossley double-deck bodywork were built. Unlike the earlier vehicles, these trolleybuses had two axles.
There were three of the former Glasgow trolleybuses saved from scrap: TB78, TBS13, and TBS21.
TB78 is fully restored and in operation at the British Trolleybus Society museum, Sandtoft. It remains the only Scottish double-decker trolleybus in existence. 
TBS13 was displayed at the original Glasgow Museum of Transport in Albert Drive, Pollokshields, and moved with the museum to the Kelvin Hall. When that museum closed and some its collection was transferred to the new Riverside Museum in 2011, TBS13 was not one of the exhibits fortunate enough to be granted a place there; it resided at the Glasgow Museums Resource Centre at South Nitshill where it was not on public view except by arrangement at the Glasgow Transport Museum. However, to mark the 50th Anniversary of the end of the Glasgow system, TBS13 was returned to public display at the Glasgow Riverside Museum in May. It is now the only Scottish single-decker trolleybus in existence.
TBS21 was eventually scrapped in 2015. TBS21 was almost the last trolleybus to run on the streets of Glasgow. It had been repainted inside and out by GCT at Larkfield Works and, having been purchased by the NTA, it was allowed to tour the system on the final evening and ran behind the final service trolley (TB105) on the last 105 from Queen's Cross to Hampden Garage, for which it displayed a specially made 'Scotland’s Last Trolleybus' blind. It was, however, trumped by TB123, (the last trolleybus built for the city) which made a final trip under power the following morning (Sunday 28 May 1967) from Hampden to Gorbals Cross; from there it was towed by CUS807 to Ibrox bus garage where, as a final show of independence, it reversed into line on its batteries. 
It was also the only preserved trolleybus to run under wire in Scotland, England, and Wales - it completed tours of Cardiff in September 1967 and Bournemouth in May 1968. In the years since then, it has led a peripatetic existence, often stored outside, its condition deteriorating all the while until, eventually, it wound up at the ill-fated Beith Transport Museum in North Ayrshire. It was subsequently offered for sale again and there was a real chance that it might have been acquired by Sandtoft although its restoration would have been a long and expensive business. Unfortunately, its eventual purchaser, who apparently tried very hard to find a suitable home for it, had to accept the inevitable and TBS21 was scrapped in late 2016.
Closure.
The trolleybuses (as well as the city's much larger tram fleet) used electricity generated at the Pinkston power station, later sold to the South of Scotland Electricity Board. Following the closure of the tram system in 1962, the maintenance of the electrical supply system solely for the trolleybuses became impractically expensive.
Construction of approach roads to the Clyde Tunnel led to the abandonment of trolleybus services to Linthouse and Shieldhall in 1964. In 1965, Glasgow Corporation agreed to purchase 150 new Leyland Atlantean diesel buses to replace the remaining trolleybuses. Glasgow's last trolleybuses ran on 27 May 1967.
