Today, CRO happened 3 kms before Gotan Railway Station. 02477 Jodhpur - Jaipur InterCity High Court SF Express was in high speed powered by BGKT 40344 WDP4D. A cow herd was crossing track but a cow was left behind suddenly it ran and crossed fencing and came in front of loco. I was capturing video and was away as the cow came suddenly so couldn't do anything even the loco pilot made honkings but couldn't apply emergency brakes as the train was in high speed.
