Indian Railways to use vacuum toilets

• Stinking washrooms on trains may become a thing of the past with the railways launching the trial run of vacuum toilet on Dibrugarh Rajdhani.
• Fitted in the First AC coach at an estimated cost of about Rs 3 lakh, the vucuum toilet is also equipped with the bio-digester system.
• Railways will initially install 80 such toilets on a Shatabdi Express train.
• So far, railways have replaced 17,388 conventional toilets with bio-toilets, about 17,000 more are to be replaced by the end of this year.
• The environment-friendly vacuum-based toilets consume much less water than conventional ones despite improved efficiency of the flush, aiding water conservation efforts and also help prevent corrosion of rail tracks.
