One of the greatest offlinks of 2016... 4hrs late running 22824 NDLS-BBS Rajdhani with Tughlakabad WAG-9 arriving at BLS station... This offlink had been given with this train because of loco failure in between BDL and MZP as the speeding train collided with a railway tie/sleeper kept on the track and the previous loco suffered damage... Finally this loco was called on for rescue..
