Development Cell of the Railway Board has come up with a design that combines the advantages of vacuum toilets and those of bio-toilets to create a new design of a hybrid vacuum toilet.
One such toilet has been fitted in the Dibrugarh Rajdhani for trial purposes.
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.
The prototype consists of a custom designed Vacuum toilet adapted from a commercially available vacuum toilet that is used in aircrafts which evacuates its discharge into a bio-digester tank which is now successfully proven in the bio-toilets of Indian Railways.
