The Reading trolleybus system served the town of Reading in the English county of Berkshire and was owned by Reading Corporation, which had operated an electric tramway since 1901. As there was a need for major refurbishment of the tramway in the 1930s, they decided to replace it with a trolleybus network. The first route was converted on , and by mid 1939, trolleybuses were running over most of the tramway routes, with the last tram running on 20 May. By the standards of the various now-defunct trolleybus systems in the United Kingdom, the Reading system was a moderately sized one, with a total of four routes, and a maximum fleet of 63 trolleybuses, a size that lasted from 1 December 1950 to 27 March 1952.
Reading saw a large increase in population during the Second World War, and extra vehicles were obtained to meet the demands for transport. During this period, all of the termini were given new non-geographical names, in case there was an invasion, but most were reverted when hostilities ceased. In the post-war period, small extensions to the system continued to be made, and although a batch of second-hand trolleybuses were purchased in 1949, most acquisitions were new, with a final batch of twelve obtained from Sunbeam Commercial Vehicles in 1961. The demise of the system was hastened by the manufacturer of overhead wiring announcing that they would cease production of these items, and by some major roadworks taking place in the town, which would have required reconstruction of the overhead wiring. The first closure of a route took place in July 1965, and the system closed on .
Reading was at the forefront of the trolleybus preservation movement, when Reading Transport Society obtained the first British trolleybus to be privately preserved. Another five Reading vehicles were eventually saved, including one that was sold to Teesside for further service when the Reading system closed. The Reading Transport Society spent years searching for a site where their vehicles could be exhibited and operated, and were instrumental in setting up The Trolleybus Museum at Sandtoft in 1969, where all of the preserved vehicles are normally stored. The Society was rebranded as the British Trolleybus Society in 1971, reflecting the wider remit that they now had.
History Reading Corporation had run an electric tramway network since 1 November 1901, and by the 1930s the tramcars were showing their age, as the fleet still consisted of the 30 vehicles that had been bought for the opening of the system and another six that had been acquired a year later, although many had been fitted with new bodywork at the Mill Lane depot in the 1920s. In 1931 a Tramways (Future Policy) Subcommittee was created, to consider what should be done when replacement of the tramcars became necessary. Formal visits were made to see several trolleybus systems, and the committee proposed a trolleybus network as the solution. As they were already promoting a bill in Parliament to authorise the supply of electricity, the initial plan to obtain powers to convert the Caversham Bridge to Whitley Wood route became a more general request to cover the conversion of all the tram routes, and these powers were enshrined in the Reading Corporation Act 1935 (25 & 26 Geo. 5. c. xc).
Trams on the route along Erleigh Road had been withdrawn on 7 August 1932, to be replaced by motorbuses, The overhead wiring on part of the route was altered for trolleybuses, and a Sunbeam demonstrator was obtained in May 1936 to allow driver training to take place. The vehicle was fitted with a skate to allow it to run under the tramway wires between the depot and the test track, and although there was never a public trolleybus service on the Erleigh Road route, passengers were often carried free of charge during this period to provide a taster for the new mode of transport. Trams were withdrawn from the Caversham to Whitley Street route on 15 July 1936, to be temporarily replaced by motor buses while the conversion of the overhead wiring was completed. A formal opening took place on 18 July, with the Mayor driving the Sunbeam demonstrator, now No.1 in the corporation's fleet. The other five vehicles obtained to provide the service were an eclectic mix, with one each from Associated Equipment Company (AEC) of Southall, Guy Motors of Wolverhampton, Leyland Motors of Leyland, Ransomes, Sims & Jefferies of Ipswich, and another Sunbeam. All had lowbridge bodywork by Park Royal Vehicles, with 50 seats on the demonstrator and 52 seats on the rest.
The different makes of trolleybus were assessed, and an order was placed with AEC for 25 vehicles to enable the rest of the trams to be withdrawn. These were of highbridge design, with a central gangway on the top deck, rather than the offset sunken gangway of the lowbridge design. Because a highbridge design is inherently taller than a lowbridge vehicle, the corporation had to obtain a special dispensation from the Ministry of Transport, as low bridges on Caversham Road and Oxford Road meant that the overhead wires were very close to the roof at these locations. As well as the price being competitive, AEC had the advantage that their works were only away. Delivery of the first vehicle occurred on 14 December 1938, and the final one arrived on 18 April 1939. New overhead wiring was erected, and where possible, the tramway wiring was removed, with the trams using one of the trolley wires to obtain their power. The "main line" tramway route ran from Oxford Road, near its junction with Craig Avenue in the west, to Wokingham Road in the east, with a branch to London Road. The trolleybus route would be somewhat longer, with an extension along Wokingham Road to the "Three Tuns" public house at one end, and a longer extension to "The Bear" public house in Tilehurst at the other. Driver training took place at the Tilehurst end, where there was no conflict with the trams, and the final trams ran on 20 May 1939, bringing 38 years of tramway operation to an end. Trolleybuses ran along the extended route on the following day.
The onset of the Second World War brought its own problems, with Reading seeing a rapid increase in population, from 100,000 to 140,000 in just two years, and corresponding increases in the number of passengers trying to use the system. Attempts to hire surplus trolleybuses or motor buses from other operators failed, but in 1942 an order was placed with Sunbeam for six utility-bodied vehicles, which arrived in 1943. All of the termini were renamed to remove geographical information, in case of invasion, with Caversham becoming Promenade, Whitley becoming Whit Pump, Tilehurst becoming Bear Inn, Wokingham Road becoming Three Tuns, and London Road becoming Liverpool Road. When hostilities ceased, all but Liverpool Road reverted to their pre-war names. On 31 July 1944 a new branch was opened from Oxford Road to Kentwood, enabling trolleybuses to replace motor buses with a consequential saving in precious oil based fuel.
In 1949 the Whitley Street line was extended along Northumberland Avenue on 5 June, with a branch to Whitley Wood and a short branch to Reading General station opening on 7 August. Subsequent short extensions took the system to its full extent, with the Kentwood route running to Armour Hill and the Northumberland Avenue line running to the junction with Whitley Wood Road. Services on the extended system were provided by purchasing twelve three-axle Karriers from the Huddersfield system, although only six were used in public service, and a batch of 20 vehicles from British United Traction with air-operated doors on the rear platform were delivered in 1950. The final additions to the fleet were twelve Sunbeams with front entrances, which arrived in 1961.
Demise By 1965, many UK trolleybus systems had closed, and there were just 16 still in operation. The main manufacturer of the overhead equipment and wiring for trolleybus systems, British Insulated Callender's Cables, gave notice that they would cease production by the end of the year, because of difficulties in making the wire in sufficient quantities for it to be economic. At the same time the trolleybuses came in for some bad publicity in the local press because they cost more to operate compared to motor buses and they were inflexible, even though the trolleybuses were profitable (Reading's motor buses made a loss), faster and less polluting. Reading Corporation decided to abandon the trolleybus system, and the routes were phased out between July 1965 and November 1968.Reading trolleybus plan-first step Commercial Motor 4 November 1966End of Reading trolleybuses Commercial Motor 8 November 1968
The first route to close was the Caversham Bridge section, on 10 July 1965. At the same time, the wiring allowing the trolleybuses to serve the Stations was altered, in preparation for the introduction of a one-way system in the area. The decision to abandon the system was taken at a Council meeting on 26 July 1966, and large-scale closure began on 8 January 1967, when services on the Whitley Wood branch were withdrawn. Next to go were the route to Northumberland Avenue and the branch to the stations, which ceased on 31 December 1967. The Liverpool Road and Armour Hill branches closed on 3 March 1968, leaving just the main line from Tilehurst to Wokingham Road, which lasted until 3 November 1968, with trolleybus No.144 making the final ceremonial trip.
The UK's first contra-flow bus lane was instigated along Kings Road, when that road was made one-way in the early 1960s. The trolleybuses continued to operate two-way, as it was considered uneconomic to erect wiring on the new inbound route, London Road. The concept of the contra-flow bus lane proved successful, and was adopted in other places for motor buses. The extended main line from the Three Tuns to the Bear still exists today as Reading Buses route 17, the town's busiest and most frequent route, and the first to be designated a premier route. This was a scheme to upgrade the quality and level of service, including better provision for passengers with reduced mobility, realtime service information, and a higher capacity, more reliable bus service. This standard was rolled out on route 17 in 2004.
Depots The Corporation owned a tram depot on Mill Lane, near to where the north-south Caversham to Whitley Street route crossed the east-west Wokingham Road to Norcot route. The site also contained a power station equipped with three boilers and four steam engines, which could supply 400 kW at 500 volts for the trams. For the arrival of the trolleybuses, a new depot was constructed on the same site, and temporary tracks were laid to enable the trams to be parked in the adjacent motor bus depot. Wiring was erected along a small section of London Street and all of Mill Lane, to allow the vehicles to reach either of the main routes, but there was never a public service on the depot access wires. In order to supply power to the new overhead wiring, substations were constructed at Crescent Road on Wokingham Road, Catherine Street on Oxford Road, near the "Rex" Cinema at Norcot, and at Kentwood Hill in Tilehurst. Soon after trolleybus operation began, power was available from the national grid, and the Mill Lane power station was shut down in October 1936. The equipment was removed from the boiler house in 1941, and the building became the trolleybus maintenance workshop.
