Yes these r all pre-planned i think to force passengers to leave train and travel by flight. Passengers will get fedup and move to flights. I had recently travelled to Mumbai by Duronto with huge late, i have heard passengers saying " train mein daily late jane se accha flight mein jana hai, kiraya bhi bohut difference nehin hai duronto aur flight ka time bachta hai" and more discussions.
In Kolkata to Delhi route also few years back there was same situation when all trains used to run late daily, passengers moved to Flights. Earlier Kolkata to Delhi route all trains used to have huge waiting and in festival seasons ER used to run Puja special, summer and winter special trains...
more... from Howrah/Sealdah/kolkata to Delhi. Now, specials trains to Delhi is hardly given throughout the year. Even Rajdhani/Duronto doesn't gets filled all through the year. Kolkata to Delhi flights increased and almost all flights run full. Passengers moved to Flights.
Same technique is now applied to Howrah-Mumbai/Pune/Ahmedabad route.
Next target will be Howrah to Chennai route.
Intentionally harrasing passengers and Rail Minister and Rail Board doesn't do anything all sleeping silently no socause to SECR , no corrective action taken, all trains running with huge late daily.
