It is unfortunate that u are stating that trains like 7007,8561 and many more will be removed but actually it is not done.Duplication with change of numbers will be complicated due to different timings.Kindly act immediately as and when it is brought to your notice.
Thanks for your notification/concern. Many of these "removed" trains are actually marked "Cancelled" in big bold letters at the top of the train page. Also, "Cancelled" trains do not appear on train searches to avoid confusion. A "Report Cancelled" button is also being introduced in each train page, to effect the change immediately.
