Travelling today in 12817.. A1 is 2012 made & A2 is 2014 made.. Just a couple of months ago, this train possessed 2021/2022 made coaches.
Near the gates, OBHS duty sheets of trains like Mumbai Duronto, Chennai Mail, Gitanjali etc pasted.. Easy to guess, where this coach was and where this is now.. !! Atleast trains which are covering journeys in more than 15-16 hrs, allott them new coaches.. My coach has no charging point on side berths & only 2 in inside bay i.e. 2 charging points for 6/7 passengers..
