This is to register a complaint about the lack of cleaning service in Indian Railways. Until sometime back it was seen that cleanliness and hygiene was the norm in the railways as there was regular cleaning and a proper waste disposal system in place. However my recent trip in the Sanghamitra Express 12295 showed that the service was temporary because I was informed that the company to whom the tender was issued had expired so the service was stopped. As a result there were cockroaches and rats in our compartment and the neighbouring ones too. I urge the Railways department to kindly take notice and re introduce the cleaning service as it helped the 25 million passengers that travel in it daily.
