Not that much clean espicially one rake is having S1 coach with full of cockroaches. I even complained regarding this to MAQ station master and he replied me that the maintenance is done at Trivandrum and at Mangalore they dont have enough time for proper maintenace or for pest control. They minimum require 4-5 hours for proper maintenance. He noted my complaint and forwarded it to higher authorities. This was in the month of February 8, 2011.
