Where is the highly prestigious Purushottam Express ? Its the first train of ECoR and also Odisha to get LHB (except Rajdhani) along with prestigious trains like Poorva and Sampoorn Kranti. Crowded throughout the year.
BTW...I do not support Kalinag Utkal Express.
I would like to add 12817/18 Jharkhand Swarn Jayanti Express. Delhi bound trains are generally augmented with 1AC coach because of the elite class traveling to the capital which includes politicians too. Overnight trains perform best with 1AC class if its running between important cities like Howrah-Danapur Express, Darjeeling Mail,...
more... Sri Jagannath Express, Howrah-Jamalpur Express, Howrah-Hatia Express, Howrah-Puri Express, Tapiswini Express ,etc because of the low fare compared to long distance trains. This is the reason most of the long distance trains have 1AC-cum-2AC coach.
