Respected admins, i think some problem has developed in your site, how can two or more trains pass the same location at the same time on the same day? I was checking the action sequence for Chola, and found out about this, i request you to please rectify it. As of now, 12454 RNC Raj departs NDLS on Mon and Thu, and 12453 arrives on Sun and Wed. 12440 RNC Raj departs NDLS on Tue and Fri, and 12439 arrives on Mon and Thu. 12878 RNC GR departs NDLS on Wed and Sat and 12877 RNC GR arrives Tue and Sat.
