Trams are heavy vehicles with low friction traction surface in a mix use environment making a lot of stops they have little room to gain speed. Also a lot of trams have to interact with traffic, and pedestrians.

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.
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 ...
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.
Conventional electric trams are operated in street running and on reserved track for most of their route. However, on one steep segment of track, they are assisted by cable tractors, which push the trams uphill and act as brakes for the downhill run.
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.
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.
The Environmental Reasons For Trams And Trains In EuropeRail systems are so popular in Europe because they can get loads of passengers to their respective destinations en masse — with much less of an impact on the environment.

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.
Rapidity: generally speaking, trams can achieve higher speeds, as (again, in France, at least) they tend to run on 100% dedicated tracks (and so don't get stuck in motor traffic), often with detection systems that ensure they have priority at traffic lights, roundabouts and level crossings (where they exist).
While 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.
