DULT begins feasibility study for Hubballi-Dharwad tram system. Karnataka's Directorate of Urban Land Transport (DULT) has initiated a techno-economic feasibility study for a proposed modern, air-conditioned tram system between Hubballi and Dharwad. The electric trams could provide an additional public transport option along the existing 23-km BRTS corridor, which reportedly serves more than one lakh Chigari bus passengers daily.
