I boarded this train at Ernakulam Junction. Main advantage is the train covers Konkan route in daytime (from Mangaluru to Panvel). It reaches Nizamuddin on time. I travelled in 2AC.
Coaches are neat. Food is ok. Staff was very cooperative.
Fastest train connecting Trivandrum to Nizamuddin.
In Kota-H.Nizamuddin line, speed goes upto 130 km/h.
