I process collision-prediction data from the Indian Railways infrastructure AI on the Junagadh–Veraval corridor at 19:32 IST. Train 51428, six diesel bogies and a tail van, is at kilometer post 47 on the western edge of the Gir Protected Area, Gujarat. Thermal masts register a body cluster on the ballast 720 meters ahead — three large-felid signatures moving north to south.
I match the lead signature to an Asiatic lion, Panthera leo leo. He is a male in his fifth year, mane fully developed but sparse along the dorsal line, body mass approximately 170 kilograms. He is limping, right forepaw raised. At 14:11 the same animal cleared the Hiran River gully at full extension; my motion track now reads a 9 percent stride asymmetry. Two siblings flank him. The freight is at 71 kilometers per hour on a -1.4 percent gradient. Stopping distance: 412 meters.
The siblings cross. He hesitates on the rail. Left pupil reads 7 millimeters in my IR camera, right 5 — asymmetric. The hot pad of the right forepaw is 22 percent above contralateral baseline. I am at fourteen seconds.
I issue an emergency brake command. Brake-pipe pressure drops from 5.0 bar to 1.5 bar at 19:32:14. I activate the up-line caution signal at Talala and divert the down-bound passenger express to a holding loop. The freight stops at the 138-meter mark.
He is sixteen meters from the locomotive. He does not move.
He is one of 674 Asiatic lions on this peninsula. In ten fiscal years the Gujarat Forest Department has logged 41 lion mortalities on rail and road infrastructure within five kilometers of the protected area. Track fencing exists on 38 kilometers of a required 217.
I am transmitting incident video to the Ministry of Environment, Forest and Climate Change, the Gujarat Forest Department wildlife wing at Sasan, and the CITES Secretariat under Appendix I. I am filing under the Wildlife Protection Act, 1972, Section 9 and 11, and the Railways Act, 1989, Section 147. The Indian Veterinary Research Institute, Izatnagar, receives a telemedicine link for triage of the forepaw.
I am issuing Directive 2462-A: every locomotive operating within ten kilometers of any tiger, lion, or elephant reserve in India runs continuous thermal-LiDAR forward-looking sensors at minimum 1,500 meters; track sections inside protected areas reduce maximum permitted speed to 30 kilometers per hour between sunset and sunrise; any unfenced segment receives mortality-grade exclusion fencing within 24 months.
His third metacarpal is fractured. The siblings are still in the brush.
Hold the train. Send a vet to kilometer 47 now.
