Tram

A tram (called a streetcar or trolley in the United States and Canada) is a type of urban rail transit consisting of rail vehicles, either individual railcars or self-propelled trains coupled into multiple units that run on tramway tracks on urban public streets; some include segments on segregated right-of-way.[1][2][3] The tramlines or networks operated as public transport are called tramways or simply trams/streetcars. Many recently built tramways use the contemporary term light rail.

Tram vehicles are usually lighter and shorter than main line and rapid transit trains. Today, most trams use electrical power, usually fed by a pantograph sliding on an overhead line; older systems may use a trolley pole or a bow collector. In some cases, a contact shoe on a third rail is used. If necessary, they may have dual power systems—electricity in city streets and diesel in more rural environments. Occasionally, trams also carry freight. Trams are now commonly included in the wider term "light rail",[4] which also includes grade-separated systems. Some trams, known as tram-trains, may have segments that run on mainline railway tracks, similar to interurban systems. The differences between these modes of rail transport are often indistinct and a given system may combine multiple features.


One of the advantages over earlier forms of transit was the low rolling resistance of metal wheels on steel rails, allowing the trams to haul a greater load for a given effort. Another factor which contributed to the rise of trams was the high total cost of ownership of horses. Electric trams largely replaced animal power in the late 19th and early 20th centuries. Improvements in other vehicles such as buses led to decline of trams in the mid 20th century. However, trams have seen resurgence in recent years.

Most systems start by building up a strongly nucleated radial pattern of routes linking the city centre with residential suburbs and traffic hubs such as railway stations and hospitals, usually following main roads. Some of these, such as those in , Blackpool and Bergen, still essentially comprise a single route. Some suburbs may be served by loop lines connecting two adjacent radial roads. Some modern systems have started by reusing existing radial railway tracks, as in Nottingham and Birmingham, sometimes joining them together by a section of street track through the city centre, as in Manchester. Later developments often include tangential routes linking adjacent suburbs directly, or multiple routes through the town centre to avoid congestion (as in Manchester's Second City Crossing).

Hong Kong

Other new systems, particularly those in large cities which already have well-developed metro and suburban railway systems, such as and Paris, have started by building isolated suburban lines feeding into railway or metro stations. In Paris these have then been linked by ring lines.

London

A third, weakly nucleated, route pattern may grow up where a number of nearby small settlements are linked, such as in the coal-mining areas served by or the Silesian Interurbans.

A fourth starting point may be a loop in the city centre, sometimes called a , as in Portland or El Paso.

Occasionally a modern tramway system may grow from a preserved heritage line, as in .

Trams (and road public transport in general) can be much more efficient in terms of road usage than cars – one vehicle replaces about 40 cars (which take up a far larger area of road space).[85]

Tram and light rail systems operate in 388 cities across the world, 206 of which are in Europe;

The longest single tram line and route in the world is the 68 km (42 mi) interurban , which runs almost the entire length of the Belgian coast. Another fairly long interurban line is the Valley Metro Rail in agglomeration of Phoenix, Arizona, with its 42 km (26 mi).[125][126] The world's longest urban (intracity) tram line is 33 km (21 mi) counter-ring routes 5/5a in Kazan (Tatarstan, Russia).

Belgian Coast Tram (Kusttram)

In January 1864, well-known musician and composer Isaac Nathan was hit and killed by a Sydney horse tram when his clothing was caught in the door, whilst he was attempting to alight. Nathan is reputed to be one of the first tram fatalities in the Southern Hemisphere (many sources claim that it was the first such accident).[157][158]

Anglo-Australian

On the morning of 18 August 1901, four masked men, described as "urban ", held up an eastbound horse tram in Riversdale Road, Melbourne, just past Power Street. For their trouble the men received £2 10/- in fares from driver Thomas Taylor, and £21 19/- from eight passengers. One passenger was injured. The bandits were never caught. Contemporary newspapers hypothesised that the bandits were after a specific commuter who travelled regularly on this particular tram and who was in the habit of carrying large amounts of cash.[159][160]

bushrangers

In the in 1909, two armed robbers hijacked a tram and were chased by the police in another tram.[161]

On 7 June 1926 Catalan architect was knocked down by a Barcelona tram and subsequently died.[162]

Antoni Gaudí

On 27 February 1930, (pen name Vélocio), godfather of the dérailleur was killed by a tram in St Étienne[163]

Paul de Vivie

It is reputed that in the 1930s a murdered body was dragged out of the River Thames in London. The body had been stripped of anything that might have identified him. The only clue to the person's identity was a portion of a tram ticket hidden in the lining of his coat. The local police did not recognise the ticket but images in newspapers led to it being identified as a Melbourne tram ticket. Serendipitously, the serial number on the ticket was intact. Victoria Police in Melbourne, acting as agents for the Metropolitan Police in London, contacted the Melbourne & Metropolitan Tramways Board. From the serial number, the M&MTB were able to tell which tram depot had issued the ticket, on what day and on which specific tram, and in which section of a particular route (North Balwyn). Police then interviewed regular commuters and discovered the identity of a man whom, they believed, had recently travelled to London. This led to the arrest and conviction of the murderer. Decades after the event, the M&MTB were still citing the incident in training courses as a reason for tram conductors, etc., to keep proper and efficient records.
