SER is a 3rd class zone of IR. Almost 90% trains runs late daily. Passengers suffering and our worst railway minister has no headache busy in publicity stunts.
Howrah -Mumbai Duronto Exp is intentionally delayed by SER, SECR just to give passengers to Flights. Just do an RTI about increase in nos of passengers and flights between Kolkata and Mumbai and Pune in last 5 yrs. You will see number of passengers and flights between Kolkata and Mumbai has increased and number of passengers decreased in Howrah-Mumbai / Pune Duronto exp.
1st...
more... Howrah to Delhi route was destroyed intentionally, then Howrah-Mumbai, Howrah -Pune route and now Howrah-Chennai route. Next is Howrah-Bengaluru route. All these routes are intentionally been destroyed by poor punctuality of trains and dirty trains. Same tactics just to give more and more passengers to private flight operators and with high flight tickets nowadays.
IR will make losses year after year then SELL to Private Adani, Ambani, etc.
Vande Bharat is the next private trains in future according to me. Soon all VB trains (after VB sleeper, VB Metro starts ) will be given to private players to run and maintain rakes according to me.
