Mangalore Chennai Mail and OBHS
While having OBHS in any train is welcome, this one is an immense nuisance between Mangalore and Calicut. The train just starts from Mangalore but the OBHS staff, some of them a bit rude too jostle with the passengers in the Cannanore-Calicut section. this kind of cleaning could be completeed in Mangalore Central yard itself and the secondary cleaning can be after PGT.
