With bio-toilets slowly turning out to be a success on trains, the Central Railway now plans to construct compost loos for women at all the suburban stations. The authorities have already floated tender for the project. The stations where the toilets would come up first include Mulund, Nahur, Bhandup, Kanjurmarg, Vikhroli, Ghatkopar, Vidyavihar, Govandi and Mankhurd. Sources said that after the bids were opened up in March, work would be completed in the next three months.
