Indian Railways — toilets

I'm travelling in bangalore kannur express train regularly.. Compartments are new.. But toilets are stinking so bad.. Smell is so bad so that it's not able to sleep too.. This problem of hygiene in toilets has been there with railways for years and not been sorted out.. Also can't blame that people are also responsible.. But for new compartments atleast an effort should be made to make toilet clean.. Request to take action. I had sent mail before too but in vain.. God knows whether somebody acts.. Railways are public transport and even foreigners see these as a bench mark for our progress.. So lots of improvement to be done for hygeine in trains.. Now situation is just pathetic
