Talk to a RailFan - you will learn a LOT about Trains.

Additional CC coaches should be added by removing two of the reserved coaches. Chair car tickets are sold quickly before weeks than the 2S ones. Most of the time, the train is occupied by unreserved passengers after TPJ. So it is better to increase the CC coaches. The same should be done for it's pair Vaigai also.
Seen here is the majestic and first WDP 4B of GOC #40063 which regularly hauls Pallavan from KKDI to TPJ.
