Yes, 3 weeks ago, I urgently had to go to ERS from KPD.
Since I had not time for booking, I decided to take this train (hoping i could have a good sleep in empty seats) . But the train was full.
Got a Seat luckily. And also Surprising most of them were to Ernakulam itself. A lot of workers had deboarded at ERN as train had a stop there for entry to ERS.
