There is a communication gap between SCR and ECOR every time and looks like they don't give information to ECOR and it continues with reservation. Even many spls are announced till July end. The 4 trains being cancelled every 2-4 weeks reservation is opened and cancelled from EcOR only on starting date and its recurring process.
One more thing if you have booked tickets for May 5th in Uday reservation is done in both directions, tickets are allowed to be booked. Suppose the train is cancelled from April 30th and...
more... notification issued on April 29th the booking is not allowed further, but the tickets already booked are not cancelled and money returned till 4th May chart preparation, money will be credited in 4-7 days in May after journey date only. So you need to book in alternate trains with extra money. In some routes the cancelled trains are restored in last minute.
