Sir,
I m not fully agree with you. On Sunday and other holidays also in some major cities counters are working full day. Here in chennai we have two counters working today also one at central and one at egmore after 14.00 hrs apart from current reservation counters.......but the difference is - it book tickets only for the train leaving before 11.00 hrs of next day for which chart will be prepared before opening of next day's counter.
