Coromandel & its Counter Part Madras Mail are one of the dirtiest rakes of South Eastern Rly.Even Howrah Yesvantpur has also become very dirty especially the sleeper coaches.I dont know why Santragachhi Coaching Yard is showing so much negligience towards the Rakes maintained by it.Previously it maintained all the rakes very neat & clean.I think they should learn something from SWR & SCR.
