Tita Gaur wagons is a 26 year old Kolkata based company. The stock has delivered an 850% return in the last three years. It began operations in the early 80s, manufacturing railways related stuff that was at the bottom of the value chain. In 2015, it bought a wagon manufacturer on Rajasthan, which had already the capacity to make 2,400 units a year. And this was the most Tita Gaur needed to foray into the passenger rail segments.
