If you’d like to do a journey on a complete Blue Formation, I would suggest you to take 03245 Danapur-Smvt Bengaluru SF special or its counterpart, tbh it’s one of the worst train to get delay for more than 10hours, plan a short journey in this train just to experience this final blue ICF era. Among all the zones, East central railway maintains these rakes very well. If you’re around ECR, it’s easy to witness plenty of passenger trains running with these Blue versions. 8hrs delayed 03245 Danapur
