What are differences between IRY/IR20 and LHB in terms of ride comfort? Are there any plans of NR upgrading the ASR Swarna Shatabdi to LHB?
To add, IRY/IR20 coaches of this train earlier sported a 'white and blue' livery, similar to ICF Shatabdi livery which was later changed to 'only blue' livery. Now it runs with the 'blue and grey' livery of LHB Shatabdi.
