The engines of Indian Railway Trains now will have its own little Bio-Toilet installed.
The toilets will be modern with its own intelligence. For example, to ensure safety, the toilet door will not open while the train is moving. Once the train halts to a stop, the toilet can be used. Also, while the driver is inside the toilet, Brakes will be engaged and cannot be released until the driver comes out.
This little step to serious comfort of the driver was also publicized by our Railway Minister Mr. Suresh Prabhu in the 2016-17 Rail Budget speech.
India has close to 60,000 train drivers working currently including a growing number of female drivers. They will be hopeful of the realization of this initiative.
