The Development cell of Indian Railways has developed a “Hybrid Vacuum Toilet” design that combines the advantages of Vacuum toilets and Bio toilets. It will help to maintain hygiene and cleanliness in toilets or tracks of Indian Railways as there will have no direct evacuation of human waste. This newly developed toilet facility has been fitted on trial basis in Dibrugarh Rajdhani. The concept of a hybrid vacuum toilet is a first ever system of its kind to have been developed and built by any railway system in the world.
