Happy to post this review after a long time.
From Tirunelveli New Bus Stand(9:35 pm) to Coimbatore Gandhipuram(4;05 am).
Bus :SETC- Marthandam -Ooty Non A/c 2+2 -UD (White colored one).It belongs to Marthandam depot.
Both drivers were fast and bus clocked between 80-85 Kmph as per GPS.
There was no dinner break.
Overtook all SETCs, Arthi Travels(2 nos), Essar Travels ,and a few more omni buses.
Second driver took over from rest stop near Dindigul-Palani road and he was a bit rash.
6.5 hrs, I feel is a very good one by all standards.
