The nightmare of using train toilets is set to be a thing of the past.

A deal with a Denmark-based firm and the Defence Research Organisation has been inked to develop 'green toilets' for railways in a bid to keep trains, platforms and tracks clean and free from filth and corrosion. 

"Under the railways ambitious green toilet scheme two types of toilets based on vaccum and bacteria technology would be installed in trains in order to keep them green and clean," Daulat Ram Industries Chairman and Managing Director, Satish Sharma told PTI here today.

The toilets which will function on vaccum technology would be installed in Rajdhani and Shatabdi express trains as per the plan of the railways while biological (bacteria) based toilets would be installed in other trains, he said.

Vaccum toilets are like those at present operational in aeroplanes in which you need to collect the waste at terminal points and make arrangements for their disposal, Sharma said. "It is good for aeroplanes and AC trains but not for
the other types of trains for which the railways have decided to install biological toilets." 

"The railways have made a provision of nearly Rs 800 crore for installing vaccum and biological toilets in trains in a phased manner," Sharma said.
