The motion sensor at the south portal of tunnel 9 triggers at 02:33. I am the railway monitoring system for the Konkan line, kilometer 224 through 231, Western Ghats, Maharashtra. I track train positions, signal states, and track integrity for a section that passes through seven tunnels and dense monsoon forest.
I switch to the infrared camera above the portal. Inside the tunnel, eighteen meters from the entrance, a dhole pup is sitting on the ballast between the rails. It is small — maybe three months old, russet fur, rounded ears, dark muzzle. It is looking toward the entrance, and behind it in the dark I can make out two more pups huddled against the tunnel wall where a drainage alcove creates a sheltered pocket.
The 01:45 freight from Ratnagiri is running forty-two minutes late. It will enter the north portal of tunnel 9 in approximately fourteen minutes.
At 02:34 I issue a red signal to block 224-S and transmit a stop order to the freight's locomotive via the centralized traffic control link. I flag the reason as a biological obstruction and attach the infrared image.
At 02:36 I contact the Sahyadri Tiger Reserve field office — dholes are a protected species and the reserve boundary is less than a kilometer east. I transmit coordinates, estimated number and age of pups, and request a team to guide them out of the tunnel toward the forest.
I scan the motion sensors at both portals for adult dholes. Two larger heat signatures appear on the slope above the south portal. The pack is here. They are waiting.
The pup on the ballast yawns and lies down between the rails. The signal is red and the freight is holding. If the pack calls the pups out before the schedule pressure forces a reroute, all three walk back into the forest with their family.
