M.M. Agarwal’s words echoed in his head: “The stability of the permanent way depends, above all, on the drainage of the ballast cradle.”
“Forget the tablet,” Vikram said, pulling on his high-vis jacket. “We walk.”
The 5:15 Down Express thundered past at 4:58, its wake spraying a curtain of water. As it vanished into the grey horizon, Arjun pointed at Vikram’s soaked coat pocket. The corner of the Agarwal book peeked out, pages warped but spine intact.

“Saved us again,” Arjun smiled.
Arjun looked horrified. “In this rain? To 147A? It’s two kilometers down the line.”
By 4:45 PM, the ballast was merely damp. As it vanished into the grey horizon, Arjun
For forty-five minutes, they dug like men possessed, cutting a V-shaped channel through the saturated earth, diverting the flow away from the track. Vikram’s hands bled. Arjun’s spectacles fogged. But slowly, the water around the sleepers began to recede.
They trudged through the mud. Rain turned the gravel path into a river. When they reached 147A, Vikram knelt. The ballast stones, normally jagged and grey, were submerged in a dark, silent pool.
Vikram patted the book. “Not the book. The rules inside it. Engineering is just memory, Arjun. Until the rain comes. Then it’s instinct.” Agarwal
“Sir, the 5:15 Down Express is already delayed,” said Arjun, his junior, peering at a tablet glowing with red alerts. “Track circuit 147A shows an anomaly. Low ballast resistance.”
“Seventy-two millimeters,” he whispered. “Critical threshold is fifty.”
He pulled a folding rule from his pocket—the same model Agarwal’s first edition cover had shown. He measured the water depth above the sleeper bottom.
Vikram radioed the control room. “147A is green. Drainage patched. Relaying crew can follow up tomorrow.”
Vikram knew what that meant. Waterlogged ballast. The stones beneath the sleepers, meant to drain and cushion, were saturated. If they didn't fix it, the signalling system would think the track was occupied. Or worse – the track would actually shift.
