Trams cannot go around obstacles, they don't mix well with bikes, they take up too much space and “they cost a fortune,” as Washington DC can tell you.

Trams get stuck in traffic, are rather uncomfortable, can only go on their rails and are inflexible, have capacity that is comparable to that of busses (far less than subways), require ugly wires above to provide power, require pedestrians to cross a lane of traffic to get in and frankly I would hate to drive anywhere ...
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.
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.
Pedestrians and cyclistsWhile collisions with cars are the most common form of tram accident, cyclists and pedestrians are the group most at risk of death during tram collisions. Cyclists may experience a loss of control if bicycle tires get jammed in tramway tracks.
Low Carbon Emissions: Trams have minimal carbon emissions making them an ideal option for eco-conscious individuals. Not only do they produce less pollution but they also emit less greenhouse gases into the atmosphere. Efficient use of Energy: Trams run on electricity which makes them highly energy efficient.
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.

The reason trams are attractive is: it turns out that trams can offer a higher frequency of service – “turn up and go” – 2 minutes in Budapest. this is due to high first cost but very low running cost (no expensive maintenance of tyres, brakes engine.
Interesting Facts about TramsFirst electric tram in England was opened in 1885 in Blackpool. There are more than 200 European cities who have active tram lines. More than 36,000 trams and light rail vehicles are currently in operation all around the world. The largest fleet of trams is in a city of Prague (920).
An extensive tram network covered large parts of London for several decades during the first half of the twentieth century. By the 1950s, however, trams were seen as old fashioned and were gradually phased out to create more room for buses and cars.
Trams are cheaper per passenger km than buses in the right circumstances. As per above the cost per passenger mile of a tram is around half that of a bus.
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.
