In Gudur - Bhubaneswar section you mostly see TTE
coming regularly to earn some extra money & to do duty as well.
In trains towards KGP - HWH - GHY or Vskp - SBP - Ranchi you don't see TTE's coming in some trains & section regularly.
TTE knows where extra collection lays...
more... & where to avoid.
You don't know even that TTE's association in Divisional level hel Auction to get some extra money during Festival & important seasons.
if Certain persons wins auction, other TTE's avoid to go in those trains and coaches.
That's why in Festival & Important seasons you only see 1 TTE handling 4 or 5 coaches only comes for collections and avoids passager problems allots same seat to other unconfirmed Tickets also.
