I can't understand the logic that if already Porbandar had a dedicated SF connectivity from Kolkata, then why another SF train SRC PBR Kavi guru express was given? Instead, IR could have removed the Okha B2 slip coach from Aradhana SF here, make it dedicated Hwh PBR Aradhana express and make that Kavi guru express to be a SRC-Okha/Veraval Kavi guru express with slip coaches separation/joining at Rajkot just like Saurashtra Mail.
At least by this Kolkata would have got dedicated trains to all these tourist cities of Porbandar, Dwarka, and Somnath.
