Prime Minister has identified the right cause. I will be more than happy to work as a volunteer and in fact this is the positive multi-layer marketing idea that you keep nominating. Indian Railways is making new bio toilets and we are making sure that we call Research and Development Organization of Indian Railways and all scientific organizations of India as well as IITs to help with technological and monetary options to keep railways clean. Indian Railways is working on total cleaniless concept, which includes total quality management in terms of end-to-end solutions, including how you collect the waste disposal. Also, we are trying to create a new agency - rail housekeeping companies - who will ensure the toilets are clean.
