from howrah, when this train rake start as coromandel,its very neat and clean. Onboard housekeeping staff are present,who clean the whole train first once after kharagpur. room spray are sprayed. and toilets are also neat and clean. SER howrah really send this rake like a king from howrah but as after 3 days it returns to howrah as chennai mail,it becomes dirty and stinky...all thanks to our aam janta travelling and negligence of houskeeping and SR.
