12424 ka to kuch samajh hi nahin aaya. It was supposed to be diverted but instead it stayed in its route and crawled. Finally reached cnb at 5 am where it was again halted for over an hour. Took record time of 15 hours to cover ndls-cnb. Was OT by all other raj except 12314 and 12034, which reached cnb just around 6 am.
