Featuring no technological improvements, and built at a cost of Rs 11.5 lakh each at Kolkata's Nonapukur depot, these swanky new trams concentrate on improving passenger comfort. They&rsquore slimmer and feature large glass windows. On the inside, the bucket seats with cushions, replacing the wooden seats, are gentler on the posterior. There are more fans, power backup and a single class of travel. Two trams have rolled out while two more are under construction (10 more have been sanctioned). The trams will travel at a leisurely 40km/hr. At a minimum fare of Rs 4, it&rsquos a joyride and everyone&rsquos invited.
