HARTASUMA takes pride in refurbishing and modernising coaches, replacing existing components and integrating new ones. Components  become obsolete after 10-15 years due to developments in technology and electronic systems. We make it a point that our engineers are trained to examine the status of both the vehicle and the individual components to ensure the preservation of functioning components and replace those that are out of date. At present, HARTASUMA is proud to have refurbished and rehabilitated more than 300 coaches.
