6 hrs slot for PM/SM after the rake is placed on pitline. What about rake stabling from PF to Pitline and back to PF, pitline availability at that hour of time all these take 1-2hrs. If there is any late of incoming train then it will added to 7-8 hrs and spls are known for late running as they are meted with spl treatment.
I have a doubt of occupancy of MYS spl with 4 2AC and also Kanyakumari spl without Nagpur that too with less sleeper 4-5 in a rake.
