Earlier when this train had 13 SL coaches ( when it ran as Slip train Tata-Alleppey and DHN-Allp), it was a preferred day option by lot of passengers between PGT, CBE, ED, Salem going to Chennai.
However now with only 5 sleeper coaches, best is to avoid travel in this train in Sleeper Class
From Allp/Ernakulam till Tiruppur somehow one can manage. After that is pathetic to travel in the SL coaches of the train.
