full_context: Document 1: Royal Institute of British Architects: Its services include RIBA Insight, RIBA Appointments, and RIBA Publishing. It publishes the RIBA Product Selector and RIBA Journal. In Newcastle is the NBS, the National Building Specification, which has 130 staff and deals with the building regulations and the Construction Information Service. RIBA Bookshops, which operates online and at 66 Portland Place, is also part of RIBA Enterprises.
Document 2: Melbourne: Melbourne has the largest tram network in the world which had its origins in the city's 1880s land boom. In 2013–2014, 176.9 million passenger trips were made by tram. Melbourne's is Australia's only tram network to comprise more than a single line and consists of 250 km (155.3 mi) of track, 487 trams, 25 routes, and 1,763 tram stops. Around 80 per cent of Melbourne's tram network shares road space with other vehicles, while the rest of the network is separated or are light rail routes. Melbourne's trams are recognised as iconic cultural assets and a tourist attraction. Heritage trams operate on the free City Circle route, intended for visitors to Melbourne, and heritage restaurant trams travel through the city and surrounding areas during the evening. Melbourne is currently building 50 new E Class trams with some already in service in 2014. The E Class trams are about 30 metres long and are superior to the C2 class tram of similar length. Melbourne's bus network consists of almost 300 routes which mainly service the outer suburbs and fill the gaps in the network between rail and tram services. 127.6 million passenger trips were recorded on Melbourne's buses in 2013–2014, an increase of 10.2 percent on the previous year.
Document 3: London: London's bus network is one of the largest in the world, running 24 hours a day, with about 8,500 buses, more than 700 bus routes and around 19,500 bus stops. In 2013, the network had more than 2 billion commuter trips per annum, more than the Underground. Around £850 million is taken in revenue each year. London has the largest wheelchair accessible network in the world and, from the 3rd quarter of 2007, became more accessible to hearing and visually impaired passengers as audio-visual announcements were introduced. The distinctive red double-decker buses are an internationally recognised trademark of London transport along with black cabs and the Tube.
Document 4: Telegram messenger: By the 1960s the number of telegrams being delivered had dropped to 10 million, and in 1976 only 844 were delivered. Consequently the Post Office took the decision in 1977 to abolish the service. The service continued for a few years and was briefly operated by British Telecom after it split from the Post Office. British Telecom announced on 19 October 1981 that the telegram would be discontinued, and it was finally taken out of service on 30 September 1982 after 139 years in the United Kingdom.
Document 5: Royal Institute of British Architects: RIBA Enterprises is the commercial arm of RIBA, with a registered office in Newcastle upon Tyne, a base at 15 Bonhill Street in London, and an office in Newark. It employs over 250 staff, approximately 180 of whom are based in Newcastle.
Document 6: Melbourne: Melbourne has an integrated public transport system based around extensive train, tram, bus and taxi systems. Flinders Street Station was the world's busiest passenger station in 1927 and Melbourne's tram network overtook Sydney's to become the world's largest in the 1940s, at which time 25% of travellers used public transport but by 2003 it had declined to just 7.6%. The public transport system was privatised in 1999, symbolising the peak of the decline. Despite privatisation and successive governments persisting with auto-centric urban development into the 21st century, there have since been large increases in public transport patronage, with the mode share for commuters increasing to 14.8% and 8.4% of all trips. A target of 20% public transport mode share for Melbourne by 2020 was set by the state government in 2006. Since 2006 public transport patronage has grown by over 20%.
Document 7: Royal Institute of British Architects: The British Architectural Library, sometimes referred to as the RIBA Library, was established in 1834 upon the founding of the institute with donations from members. Now, with over four million items, it is one of the three largest architectural libraries in the world and the largest in Europe.

Buses are operated by the state-owned Delhi Transport Corporation (DTC), which owns largest fleet of compressed natural gas (CNG)-fueled buses in the world. Personal vehicles especially cars also form a major chunk of vehicles plying on New Delhi roads. New Delhi has the highest number of registered cars compared to any other metropolitan city in India.

Document 12: Southampton: There are two main termini for bus services. As the biggest operator, First uses stops around Pound Tree Road. This leaves the other terminal of West Quay available for other operators. Uni-link passes West Quay in both directions, and Wilts & Dorset drop passengers off and pick them up there, terminating at a series of bus stands along the road. Certain Bluestar services also do this, while others stop at Bargate and some loop round West Quay, stopping at Hanover Buildings. There was a tram system from 1879 to 1949.
Document 13: Trolleybuses in Newcastle upon Tyne: By the standards of the various now - defunct trolleybus systems in the United Kingdom, the Newcastle system was a large one, with a total of 28 routes, and a maximum fleet of 204 trolleybuses. It finished on 2 October 1966 (1966 - 10 - 02).
Document 14: New Haven, Connecticut: The New Haven Division buses follow routes that had originally been covered by trolley service. Horse-drawn steetcars began operating in New Haven in the 1860s, and by the mid-1890s all the lines had become electric. In the 1920s and 1930s, some of the trolley lines began to be replaced by bus lines, with the last trolley route converted to bus in 1948. The City of New Haven is in the very early stages of considering the restoration of streetcar (light-rail) service, which has been absent since the postwar period.
