Chennai EMU - என்னோட உயிர் டா நீ

Today travelled in 17213 from NED to AWB in SL with "current booking".
Train arrived at NED 1:10 hrs late.
All SL coach doors locked.. But Luckily my coach door was open.
While entering policeman asked me "do u have reservation?"
Then...
more...

he told me to close the door.
After departure from NED TC came & asked a couple in front of my seat to show ticket. They have II class ticket. TC told them to pay the difference.
They asked TC to adjust (may be with 50 Rs.)
But TC was very sincere....He told them to go to II class.
.
Policeman was continuously walking through reserved coaches with torch and looking for doors, windows......
Excellent security....
