The Crack
The transit authority didn't answer fast enough, so Callum and Priya did the only thing left: they drove to column eleven and stood in the open access lane beneath it, waving down a maintenance supervisor who recognized Callum's name from seven years of industry rumor.
"You're the guy who called it on seven-B," the supervisor said, already reaching for his radio.
"I'm the guy who's telling you column eleven's vibration signature is doing the same thing right now. Stop the four-fifteen. Stop everything on this stretch until someone puts eyes on that bracket."
It took eleven minutes to get a track hold authorized — eleven minutes Callum spent watching commuters shuffle across the platform above them, oblivious, checking phones, exactly the way people had been checking phones on a different platform the night before.
The southbound express slowed, then stopped, two hundred feet short of column eleven, brakes shrieking against rail.
A collective exhale went through the small crowd that had gathered at the barricade — until a black SUV pulled up on the access road and Bram Halsey got out, flanked by two men in suits Callum recognized as Anchorpoint legal counsel.
"You don't have authority to halt commuter rail service," Halsey said, voice pitched for the growing crowd, calm and reasonable, a man performing calm and reasonable. "This is exactly the kind of unauthorized interference that got you terminated in the first place."
"Show them the email, Priya."
Priya held up her tablet, screen angled toward the two reporters who'd arrived at a dead run after her calls. Halsey's lawyers moved toward her at the same moment a groan — deep, metallic, unmistakable — rolled out from somewhere inside column eleven's support housing.
Everyone froze.
Dust sifted down from a hairline seam in the concrete jacket, fine as flour, drifting onto the empty track bed where a train full of people had been standing ninety seconds earlier.
"Get back," Callum said, already pulling Priya toward the barricade. "Everybody get back from the column, now—"
The groan came again, longer this time, and somewhere above them a support strut let go with a crack like a rifle shot.
