i am the frequent traveler between ERN TO MAS. Generally i opt for tvc mas mail which correct one for all by all means. Due to Onam traffic I was forced to travel to ERN through 22207 MAS TVC AC Superfast I never experienced such terrific travel in my 40 years train journey. I understood that the SR were testing their valued customers by introducing sidelined coaches by giving AC super Fast trains.
It is better to introduce doronto type trains
