“Saved us again,” Arjun smiled.
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.
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.
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. railway works engineering by m.m. agarwal pdf
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.
“Agarwal’s first rule, Arjun,” Vikram shouted over the storm, grabbing a heavy, brass-bound leveling staff. “ Never trust a sensor your boots haven't confirmed. ”
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.” “Saved us again,” Arjun smiled
By 4:45 PM, the ballast was merely damp.
“We build a temporary catch drain,” Vikram said, already moving. “Here, where the formation dips. Shovel.”
Vikram radioed the control room. “147A is green. Drainage patched. Relaying crew can follow up tomorrow.” Arjun’s spectacles fogged
“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.”
Arjun looked horrified. “In this rain? To 147A? It’s two kilometers down the line.”
