Why do trams exist?

Trams have been used for two main purposes: for carrying passengers and for carrying cargo. There are several types of passenger tram: Articulated. Cargo trams.



Trams exist because they provide a "middle ground" of high-capacity urban transport that is more efficient than buses but cheaper and easier to build than underground subways. Trams run on fixed steel rails, which offers a smoother, more predictable ride that attracts "choice riders" who might otherwise drive cars. Because they are electric and don't have heavy engines or rubber tires, they are much more energy-efficient and produce zero emissions at the point of use. In 2026, city planners favor trams because they have a "permanence" that encourages businesses to invest in the surrounding streets, creating vibrant, pedestrian-friendly corridors. Additionally, modern low-floor trams are incredibly accessible for people with strollers or wheelchairs, allowing for much faster boarding and "dwell times" compared to traditional buses with narrow steps.

They found that trams emit approximately 0.74 kg of carbon dioxide (CO2) per passenger kilometre. Buses showed the least impact, generating just 0.04 kg of CO2 per passenger kilometre, with cars and trains fairly equal at 0.25 kg of CO2 per passenger kilometre and 0.23 kg CO2 per passenger kilometre respectively.

Trams provide a useful public transport role in urban areas, but there are some disadvantages. Construction of tram routes can be costly and disruptive. Lineside equipment, electrification infrastructure and stations need to be built. Streets need to be closed for long periods, allowing tracks to be laid.

But the trams had become a political football (in Leeds it was Labour that did for them, in Liverpool it was the Conservatives). They were unwanted clutter from the past at a time when operating costs of public transport networks were rising and meeting housing targets was the big priority for investment.

Trams, which are also known as trolley cars, are much shorter and lighted in comparison. Travelling much slower than trains (in respect for the vehicular traffic around them) trams are powered by an overhead electrical apparatus or occasionally by diesel.

However, the demise of the streetcar came when lines were torn out of the major cities by bus manufacturing or oil marketing companies for the specific purpose of replacing rail service with buses. In many cases, postwar buses were cited as providing a smoother ride and a faster journey than the older, pre-war trams.
