Passenger-carrying vehicle that runs on rails laid in city streets. Streetcars in the 1830s were pulled by horses. Electric motors later supplied the power, with electricity transmitted by a trolley from overhead electric lines. From the 1890s to the 1940s, streetcars were widely used in cities around the world; they were gradually replaced by the automobile, the bus, and the subway, and by the 1950s few remained. A variant, the cable car, invented in 1873 for use on San Francisco's steep hills, is drawn by a continuous cable set in a slot between the tracks.

Tramways or street railways were common throughout the industrialized world in the late 19th and early 20th centuries, but they disappeared from many U.S. cities in the mid-20th century. In European cities they remained quite common. In recent years, they have made a comeback in many U.S. cities. Many newer light rail systems share features with trams, although a distinction may be drawn between the two, with the term light rail preferred if there is significant off-street running.
The terms “tram” and “tramway” were originally Scots and Northern English words for the type of truck used in coal mines and the tracks on which they ran—probably derived from the North Sea Germanic word “trame” of unknown origin meaning the “beam or shaft of a barrow or sledge”, also “a barrow” or container body.
Although “tram” and “tramway” have been adopted by many languages, they are not used universally in English, North Americans preferring “trolley”, “trolley car” or “streetcar”. The term “streetcar” is first recorded in 1860, and “trolley” is believed to derive from the “troller,” a four-wheeled device that was dragged along dual overhead wires by a cable that connected the troller to the top of the car and collected electrical power from the overhead wires, sometimes simply strung, sometimes on a catenary. The trolley pole, which supplanted the troller early on, is fitted to the top of the car and is spring-loaded in order to keep the trolley wheel or skate, at the top of the pole, firmly in contact with the overhead wire. The terms trolley pole and trolley wheel both derive from the troller.
Modern trolleys often use a metal shoe with a carbon insert instead of a trolley wheel, or have a pantograph. Other streetcars are sometimes called trolleys, even though strictly this may be incorrect: for example, cable cars, or conduit cars that draw power from an underground supply.
Tourist buses made to look like streetcars are sometimes called trolleys in the U.S. (tourist trolley). Open, low-speed segmented vehicles on rubber tires, generally used to ferry tourists short distances, can be called trams, particularly in the U.S.; a famous example is the tram on the Universal Studios backlot tour.
The very first tram (streetcar) was the on the Swansea and Mumbles Railway in south Wales, UK); it was horse-drawn at first, and later moved by steam and electric power. The Mumbles Railway Act was passed by the British Parliament in 1804, and the first passenger railway (which acted like streetcars did in the US some 30 years later) started operating in 1807.
The first streetcars, also known as horsecars in North America, were built in the United States and developed from city stagecoach lines and omnibus lines that picked up and dropped off passengers on a regular route without the need to be pre-hired. These trams were an animal railway, usually using horses and sometimes mules to haul the cars, usually two as a team. Rarely other animals were put to use, including humans in emergencies. The first streetcar line—the New York and Harlem Railroad’s Fourth Avenue Line—ran along the Bowery and Fourth Avenue in New York City, and began service in 1832. It was followed in 1835 by New Orleans, Louisiana, which is the oldest continuously operating street railway system in the world, according to the American Society of Mechanical Engineers.
One of the advantages over earlier forms of transit was the low rolling resistance of metal wheels on steel rails, allowing the animals to haul a greater load for a given effort. Problems included the fact that each animal could only work so many hours per day, had to be housed, groomed, fed and cared for day in and day out, and produced prodigious amounts of manure, which the streetcar company had to dispose of. Since a typical horse pulled a car for perhaps a dozen miles a day and worked for four or five hours, many systems needed ten or more horses for each horsecar. Electric trams largely replaced animal power in the late 19th and early 20th centuries. New York City closed its last horsecar line in 1917. The last regular mule drawn streetcar in the U.S., in Sulphur Rock, Arkansas, closed in 1926. During World War II some old horse cars were temporarily returned to service to help conserve fuel. A mule-powered line in Celaya, Mexico, operated until 1956. Horse-drawn trams still operate in Douglas, Isle of Man. There is also a small line on Main Street at DisneyWorld, outside Orlando, Florida. A small horse-drawn service operates every 40 minutes at Victor Harbor, South Australia, daily with 20-minute services during tourist seasons, between the mainland and Granite Island across a causeway.
The tram developed after that in numerous cities, including London, Southampton, Berlin, Paris, Kyoto, Tokyo, Hong Kong and Melbourne. Faster and more comfortable than the omnibus, trams had a high cost of operation because they were pulled by horses. That is why mechanical drives were rapidly developed, with steam power in 1873, and electricity after 1881, when Siemens AG presented the electric drive at the International Electricity Exhibition in Paris.
The convenience and economy of electricity resulted in its rapid adoption once the technical problems of production and transmission of electricity were solved. The first prototype of the electric tram was developed by Russian engineer Fyodor Pirotsky, who modified a horse tram to be powered by electricity. The invention was tested in 1880 in Saint Petersburg, Russia. The world’s first electric tram line opened in Lichterfelde near Berlin, Germany, in 1881. It was built by Werner von Siemens (see Berlin Straßenbahn).
In Japan, the Kyoto Electric railroad was the first tram system, starting operation in 1865. By 1932, the network had grown to 82 railway companies in 65 cities, with a total network length of 1,479 km. By the 1960s the tram had generally died out in Japan.
Britain had the first European trams and until 1935 a large and comprehensive network of systems. For example, it was possible to go by tram across northwest England, from Liverpool to Bolton, using connecting systems. These were mostly closed by a mixture of the same forces as in the US, but with political overtones, since most of the UK systems were municipally owned. The oil and car industries did not like the fact that the municipal tram systems were powered by electricity generated from coal, and to a large extent made car ownership unnecessary.
The 1931 Royal Commission on traffic argued that trams held up cars. When it is realised that there were only one million cars then, what this meant was that trams with poorer people were holding up cars with richer people.
In the UK there was a big public reaction against tramway abandonment, much bigger than the present one against UK Post Office closures, and on a par with the reaction against the Beeching Rail closures in the 1960s, and with the same result. Tram (train) passengers largely did not transfer to the new (flexible and cheaper) buses, but bought cars- resulting in the congested cities in the UK today.
After the war continental countries had little choice but to rebuild their tramways as they could not import oil or rubber but had steel and electricity.
In the 19th century Calcutta (now Kolkata) was developing fast as a British trading and business centre. Transport was mainly by palanquins carried on men’s shoulders or phaetons pulled by horses. In 1867, the Calcutta Corporation, with financial assistance from the Government of Bengal, developed mass transport. The first tramcar travelled the streets of Calcutta on February 24, 1873, with horse-drawn coaches running on steel rails.
The first mechanical trams were powered by steam. Generally, there were two types of steam tram. The first and most common had a small steam locomotive (called a tram engine in the UK) at the head of a line of one or more carriages, similar to a small train. Systems with such steam trams included Christchurch, New Zealand; Sydney, Australia; and other city systems in New South Wales.
The other style of steam tram had the steam engine in the body of the tram, referred to as a tram engine. The most notable system to adopt such trams was in Paris. French-designed steam trams also operated in Rockhampton, in the Australian state of Queensland between 1909 and 1939. Stockholm, Sweden, had a steam tram line at the island of Södermalm between 1887 and 1901. A major drawback of this style of tram was the limited space for the engine, so that these trams were usually underpowered.
Cable cars suffered from high infrastructure costs, since an expensive system of cables, pulleys, stationary engines and vault structures between the rails had to be provided. They also require strength and skill to operate, to avoid obstructions and other cable cars. The cable had to be dropped at particular locations and the cars coast, for example when crossing another cable line. Breaks and frays in the cable, which occurred frequently, required the complete cessation of services over a cable route, while the cable was repaired. After the development of electrically-powered trams, the more costly cable car systems declined rapidly.
Cable cars were especially useful in hilly cities, partially explaining their survival in San Francisco, however, the most extensive cable system in the U.S. was in Chicago, a much flatter city. The largest cable system in the world, in the relativly flat city of Melbourne, Victoria, Australia, had at its peak 592 trams running on 74 kilometres of track.
The San Francisco cable cars, though significantly reduced in number, continue to perform a regular transportation function, in addition to being a tourist attraction. Single lines also survive in Wellington, New Zealand (rebuilt in 1979 as a funicular but still called the “Wellington Cable Car”) and Hong Kong.
Multiple functioning experimental electric trams were exhibited at the 1884 World Cotton Centennial World’s Fair in New Orleans, Louisiana, but they were deemed good enough to replace the Lamm fireless engines then propelling the St. Charles Avenue Streetcar in that city.
Electric trams (trolley cars) were first successfully tested in service in Richmond, Virginia, in 1888, in the Richmond Union Passenger Railway built by Frank J. Sprague. There were earlier commercial installations of electric streetcars, including one in Berlin as early as 1881 by Werner von Siemens and the company that still bears his name, and in Saint Petersburg, Russia, invented and tested by Fyodor Pirotsky in 1880. Another was by John Joseph Wright, brother of the famous mining entrepreneur Whitaker Wright, in Toronto in 1883. The earlier installations proved difficult or unreliable. Siemens’ line, for example, provided power through a live rail and a return rail, like a model train, limiting the voltage that could be used, and providing elecric shocks to people and animals crossing the tracks. Siemens later designed his own method of current collection, from an overhead wire, called the bow collector. Once this had been developed his cars became equal to, if not better than, any of Sprague’s cars. The first electric interurban line, connecting St Catharines and Thorold, Ontario, opened in 1887, and was considered quite successful at the time. While this line proved quite versatile as one of the earliest fully functional electric streetcar installations, it required horse-drawn support while climbing the Niagara Escarpment and for two months of the winter when hydroelectricity was not available. It continued in service in its original form into the 1950s.
Since Sprague’s installation was the first to prove successful in all conditions, he is credited with being the inventor of the trolley car. He later developed multiple unit control, first demonstrated in Chicago in 1897, allowing multiple cars to be coupled together and operated by a single motorman. This gave birth to the modern subway train.
Two rare but significant alternatives were conduit current collection, which was widely used in London, Washington, D.C. and New York, and the surface contact collection method, used in Wolverhampton (the Lorain system), Hastings (the Dolter stud system) in the UK, and currently in Bordeaux, France (the ground-level power supply system).
Attempts to use batteries as a source of electricity were made from the 1880s and 1890s, with unsuccessful trials conducted in among other places Bendigo and Adelaide in Australia, and for about 14 years as The Hague accutram of HTM in the Netherlands.
A Welsh example of a tram was usually known as the Mumbles Train, or more formally as the Swansea and Mumbles Railway. Built as the Oystermouth Railway in 1804, on March 25, 1807 it became the first passenger-carrying railway in the world. Converted to an overhead wire system it operated electric cars from March 2, 1929 until its closure on January 5, 1960. These were the largest tram cars built for use in Britain and seated 106 passengers.
Another early tram system operated from 1886 until 1930 in Appleton, Wisconsin, and is notable for being powered by the world’s first hydroelectric power station, which began operating on September 30, 1882 as the Appleton Edison Electric Company.
There is one particular hazard associated with trams powered from a trolley off an overhead line. Since the tram relies on contact with the rails for the current return path, a problem arises if the tram is derailed or (more usually) if it halts on a section of track that has been particularly heavily sanded by a previous tram, and the tram loses electrical contact with the rails. In this event, the underframe of the tram, by virtue of a circuit path through ancillary loads (such as saloon lighting), is live at the full supply voltage, typically 600 volts. In British terminology such a tram was said to be ‘grounded’—not to be confused with the US English use of the term, which means the exact opposite. Any person stepping off the tram completed the earth return circuit and could receive a nasty electric shock. In such an event the driver was required to jump off the tram (avoiding simultaneous contact with the tram and the ground) and pull down the trolley before allowing passengers off the tram. Unless derailed, the tram could usually be recovered by running water down the running rails from a point higher than the tram. The water providing a conducting bridge between the tram and the rails.
In some places, other forms of power were used to power the tram. Hastings and some other tramways, for example Stockholms Spårvägar in Sweden, used petrol trams and Lytham St Annes used gas trams. Paris operated trams that were powered by compressed air using the Mekarski system. In New York City some minor lines used storage batteries.
The latest generation of light rail vehicles is of partial or fully low-floor design, with the floor 300 to 360 mm (12–14 inches) above top of rail, a capability not found in older vehicles. This allows them to load passengers, including in wheelchairs, directly from low-rise platforms that are not much more than raised sidewalks. This satisfies requirements to provide access to disabled passengers without using expensive wheelchair lifts, while at the same time making boarding faster and easier for other passengers.
Various companies have developed particular low floor designs, varying from part low floor, e.g. Citytram , to 100% low floor, where a corridor between the drive wheels links each end of the tram. Passengers appreciate the ease of boarding and alighting from low floor trams but for the operator the restrictions of seating layout imposed by 100% designs limits the ability to provide seats, and to vary the configuration for different city needs. There is also some evidence that passengers do not like sitting in low floor areas, especially when trams run in mixed traffic with larger vehicles looming above.
Tram-train operation uses vehicles such as the Flexity Link and Regio-Citadis, which are suited for use on urban tram lines and also meet the necessary indication, power, and strength requirements for operation on main-line railways. This allows passengers to travel from suburban areas into city-centre destinations without having to change from a train to a tram.
It has been primarily developed in Germanic countries, in particular Germany and Switzerland. Karlsruhe is a notable pioneer of the tram-train.
Goods have been carried on rail vehicles through the streets, particularly near docks and steelworks, since the 19th century (most evident in Weymouth), and some Belgian vicinale routes were used to haul timber. At the turn of the 21st century, a new interest has arisen in using urban tramway systems to transport goods. The motivation now is to reduce air pollution, traffic congestion and damage to road surfaces in city centres. Dresden has a regular CarGoTram service, run by the world’s longest tram trainsets carrying car parts across the city centre to its Volkswagen factory. Vienna and Zürich use trams as mobile recycling depots. Kislovodsk had a freight-only tram system comprising one line which was used exclusively to deliver bottled Narzan mineral water to the railway station.
In the spring of 2007, Amsterdam piloted a cargo tram operation, aiming to reduce particulate pollution by 20% by halving the number of lorries—currently 5,000—unloading in the inner city during the permitted timeframe from 07:00 till 10:30. The pilot, operated by City Cargo Amsterdam, involved two cargo trams, operating from a distribution centre and delivering to a ‘hub’ where electric trucks delivered to the final destination.
The trial was successful, releasing an intended investment of 100 million euro in a fleet of 52 cargo trams distributing from four peripheral ‘cross docks’ to 15 inner-city hubs by 2012. These specially-built vehicles would be 30 metres long with 12 axles and a payload of 30 tonnes. On weekdays, trams are planned to make 4 deliveries per hour between 7 a.m. and 11 a.m. and two per hour between 11 a.m. and 11 p.m. With each unloading operation taking on average 10 minutes, this means that each site would be active for 40 minutes out of each hour during the morning rush hour.

Joseph Conrad described Amsterdam’s trams in chapter 14 of The Mirror of the Sea (1906): From afar at the end of Tsar Peter Straat, issued in the frosty air the tinkle of bells of the horse tramcars, appearing and disappearing in the opening between the buildings, like little toy carriages harnessed with toy horses and played with by people that appeared no bigger than children.
Danzig trams figure extensively in the early stages of Günter Grass’s Die Blechtrommel (The Tin Drum). In the last chapter the novel’s hero Oskar Matzerath and his friend Gottfried von Vittlar steal a tram late at night from outside Unterrath depot on the northern edge of Düsseldorf.
It is a surreal journey. Von Vittlar drives the tram through the night, south to Flingern and Haniel and then east to the suburb of Gerresheim. Meanwhile, inside, Matzerath tries to rescue the half-blind Victor Weluhn (who had escaped from the siege of the Polish post office in Danzig at the beginning of the book and of the war) from his two green-hatted would-be executioners. Mazerath deposits his briefcase, which contains Sister Dorotea’s severed ring finger in a preserving jar, on the dashboard “where professional motorman put their lunchboxes”. They leave the tram at the terminus, and the executioners tie Weluhn to a tree in von Vittlar’s mother’s garden and prepare to machine-gun him. But Matzerath drums, Weluhn sings, and together they conjure up the Polish cavalry, who spirit both victim and executioners away. Matzerath asks von Vittlar to take his briefcase in the tram to the police HQ in the Fürstenwall, which he does.
The latter part of this route is today served by tram route 703 terminating at Gerresheim Stadtbahn station (“by the glassworks” as Grass notes, referring to the famous glass factory).

In his 1967 spy thriller An Expensive Place to Die, Len Deighton misidentifies the Flemish coast tram: “The red glow of Ostend is nearer now and yellow trains rattle alongside the motor road and over the bridge by the Royal Yacht Club ..” [Chapter 38, page 198 of the Companion Book Club edition.]
In the US, Bachmann Industries is a mass supplier of HO trams and kits. Bowser has produced white metal models for over 50 years. There are many boutique vendors offering limited run epoxy and wood models. At the high end are highly detailed brass models which are usually imported from Japan or Korea and can cost in excess of $500. Many of these run on 16.5 mm gauge track, which is incorrect for the representation of standard (4ft 8½ins) gauge, as it represents 4ft 1½ins in 4 mm (1:76.2) scale. This scale/gauge hybrid is called OO scale.
O scale trams are also very popular among tram modelers because the increased size allows for more detail and easier crafting of overhead wiring. In the US these models are usually purchased in epoxy or wood kits and some as brass models. The Saint Petersburg Tram Company produces highly detailed polyeurathane non-powered O Scale models from around the world.
It is thought that the first example of a working model tramcar in the UK built by an amateur for fun was in 1929, when Frank E. Wilson created a replica of London County Council Tramways E class car 444 in 1:16 scale, which he demonstrated at an early Model Engineer Exhibition. Another of his models was London E/1 1800, which was the only tramway exhibit in the Faraday Memorial Exhibition of 1931. Together with likeminded friends, Frank Wilson went on to found the Tramway & Light Railway Society in 1938, establishing tramway modelling as a hobby.
