The train is a small world moving through a larger world - Niraj Kumar

First of all before I start let me say everyone that I am not against Kerala Express but these are facts which I have experienced whenever I travel from Tirupur to New Delhi.
The biggest headache is getting a confirmed ticket in Kerala Express,especially in AC.
The maintenance in Kerala Express have also become worst day by day.No Cleanliness you will often see Rats in Kerala Express.

for the traveller trying to book ticket from Tirupur to New Delhi especially on Monday and Thursday please book ticket from Erode to Saharanpur in Train No 12687 and get the confirm ticket.From the day this train had been extended to Madurai I have stopped travelling in Kerala Express.
Now this is what happened.
On a fine morning around 10 AM I sat to book ticket to NZM for my parents.Now as soon as it opened within 10 minutes Kerala Express got CKWL 14 in Tatkal Sleeper Class.
Now I checked For 12687 opening quota for AC in Tatkal is 86 from Erode while Kerala have 64.I booked a successful confirmed ticket in Sleeper Class.But when Chart was prepared to my shock my parents got upgraded to AC 3 Tier. The biggest advantage of this train is Last Moment seat availability in General Quota.
I am sorry but this train 12687 is my new train for travelling to Delhi,at present no family members in my house like to travel by Kerala.
12687 do not stop at Nellore,Gudur,Itarsi,Bina,Mathura,Faridabad and food quality is good as compared to Kerala.
I know I am gonna get lots of Red but this will be useful for one who wants to travel to Dehradun or Chandigarh via Chennai.
