Indian Railway sleeper coaches have always been dependent on the windows for natural ventilation. Be it hot or cold or rainig outside, closing the windows was never a feasible option. It only meant sacrificing on the passengers comfort and the proper ventilation. The open windows also invites in loads of dust at high speeds and passengers are often prone to theft of their belongings due to open windows. The project thus is carried out from a proposal by the Indian railways for developing a forced air ventilation system for a sleeper coach thus eliminating the need for openable windows, and depending on them for ventilation. The project also aims to improve the overall hygiene and cleanliness of the coach.
