Exactly... if New Delhi Departure is after 6 and Chandigarh departure after 5 PM then even i will board this train up n down once or twice a month.
Currently i commute by Car between Delhi and Chandigarh. Kalka Shatabdi is 11 AM arrival which is too late for me, and Departure from Chandigarh is 6.30 PM which is again too late for me... 6 AM NDLS and 5 PM CDG perfectly suits me.
