Sir, i'm a regular traveller in this train and its the oldest train to SECR from Kerala, so without any choice I have to travel in this train. Regarding the Coaches and its maintainence, I can say as the train is from SR, TVC Division, TVC Officials take very less care according to me. Cockroaches are very rare in 3 AC and 2 AC coaches and if u r lucky enough u can even get RATS in the coach. U can even get "Khatmals" or "BED BUGS" as I found one which even sucked my BLOOD when i travelled in from DURG to ERN on 03/NOV/2011..
Regarding Timings this train generally runs on time except sum extraordinary conditions like Rail Roko in...
more... TELANGA or else what I suffred from, i.e. My coach 3AC caught fire because of Axle Broke Out.. :-) ;-)
Ur travelling from WARANGAL TO COIMBATORE i guess and i should warn u sir that this would be the peak time for piligrims to visit Shabarimala in KERALA..
Anyways HAPPY JOURNEY Sir.. :-)
