me too dont feel they take into consideration the opinion of the passengers or check on which day of the week the passenger demand is more. the train in my question is the newly announced 16561/16562 between YPR-KCVL-YPR. This is announced to run on a day where there are most number of trains and i feel this would soon become commercially non-viable.
If they had taken into account, the opinions of the passengers associations, they would definitely have decided to run this on a weekend.
