considerably increased.With embedding of tram tracks in the road surface, the overall surface has become smoother, easing the traffic to some extent.With the tracks now running in the centre of the heavy traffic roads, commuters are encountering difficulties in getting to the trams' stops through the traffic and as a result, fewer people are able to use the tram. Mostly trams are found to be running with many seats vacant even during rush hours. This has also caused reduction of revenue for Calcutta Tram Company. One possible remedy towards difficulty of approach-ability to the trams could be to relay the tracks on left and the right sides of the road, adjacent to the footpaths. However, relaying the track may not be possible now as the modification will need enormous expenditure. Moreover, in many thoroughfares one flank of the road is used for parking cars on payment of fee. Thereby generating revenue to the government as well as providing space for car parking. Hence, relaying tram tracks on the side of the road may not be feasible. Though trams are environment friendly, the main drawbacks of tram are that they are slow moving and occupy a lot of road space which itself is less in Kolkata. In case of derailment or breakdown of a tram the entire road gets obstructed. It will be better to keep trams in only some roads where problem of traffic jams are expected to be less. The solution to this would be to improve the maintenance of the trams as well as the support of local traffic sergeants. Signals can be modified to stop when a tram is coming, for its easy passage. Also, tram tracks should be demarcated with a small but sturdy demarcation, which will enable bikes to traverse when there are no trams. Now, several initiatives have started to improve the tram's popularity as well as increasing revenues. The results are positive. The Tram Museum is the latest addition to such schemes, which also include heritage trams' small models and meals on wheels trams i.e. with dining options. 1st AC passenger tram ran in the city in 2019. Each of the AC trams, built at the Nonapukur tram depot near Muzaffar Ahmed Sarani, cost Rs 25 lakh and is fitted with a 5.5 tonne AC unit, LED light bulbs and fans. Rickshaws, auto-rickshaws and e-rickshaws Rickshaws pulled by men are common in Kolkata
