This was the main problem in RSA. If the staff's forget to change the board, it'll be very big issue for common people. Here, Podhigai N Nellai are next to next trains. If someone wrongly boards na they've to face the issue with TTR. Currently all side boards/main boards showing their RSA. See my attached pictures.
Pic 1: A common man can confuse with this, whether it goes to Sengottai or Tirunelveli. This board is to reduce the work of ground staff which only makes issue.
Pic 2: This clearly shows the destination...
more... which help the common man to identify, which gives some work for the ground staff to change the board for their destination.
Pic 3: Name board. I saw most of the times it remains as Nellai (unchanged) and I changed it to Pothigai. This pic too I take after changing from Nellai. Not only this, I've changed lot of times Chozhan/Mangalore name boards after intimating Guard.
In general, we have to think from the common man's point of view.
