Similar thing was done when 12461 VB was started, they short terminated 20966 Intercity at GG and the platform at SBIB where 20966 was placed, it is now used for 12461.
Now passengers of 20966 heading for Haridwar who need to just change the platform at SBIB for 19031, now have to travel from GG to SBIB by road.
