Oliver heard it from below the tower’s service floor: a dry metallic ping, followed by the groan of a cable under too much weight. Nadia was already moving toward the hatch.
“Stay clear of the counterweight,” Otta called from the upper landing.
Nadia stopped at the hatch lip. Through the iron grid, the counterweight hung crooked in its guide, a dark block of iron with one bright line of cable still holding it. The rail above it had shifted a finger’s width toward the gap.
“That strand won’t hold a train,” Oliver said.
“It won’t hold much longer at all,” Otta replied. “The counterweight has slid out of its guide. If it drops, the rail goes with it.”
Nadia leaned closer, keeping her hands on the stone. The cable was frayed nearly through. Below it, a narrow ledge ran along the guide’s inner wall. The counterweight had missed it by inches.
“Can we get it onto that ledge?” she asked.
“If we move it without taking the load first, the strand will go.” Otta’s gaze flicked to Nadia’s chest. “The core could hold it for a moment.”
“No.” Nadia rose. The answer came too quickly to soften. “Not without knowing what it takes from the rail, or from me.”
Oliver glanced at the bent guide. He knew the cost of a moment borrowed from an unknown force. “Then we need another support.”
Otta led them through a narrow door into the tower’s shutter room. A thick chain ran from an old hand winch to the iron shutter over the ruined landing. Its links were dark with age but unbroken. At the chain’s far end, a ring had been set deep into the tower’s central stone pier.
“The chain can hold the counterweight?” Nadia asked.
“It used to raise the landing shutter. The ring is part of the inner pier, separate from the rail’s guide.” Otta touched the winch, not the chain. “It will reach the counterweight if we lower it. It won’t reach if the block stays where it is.”
The shutter covered an opening onto the landing that had collapsed. It had not moved since the tower’s warning changed to two flashes: no safe landing; someone listening.
“If we take the chain,” Otta said, “the shutter stays closed. There’s no second hoist.”
Nadia looked at the sealed opening. Then she turned back to the counterweight diagram scratched into the service wall. “Can we lower it onto the guide ledge and attach the chain there?”
“We can try.” Otta’s mouth tightened. “The guide’s twisted. I can’t promise the ledge will take the block.”
Next
Will the repaired chain and rail hold when Mercy’s full engine weight reaches the tower-side joint?
“Then we test the ledge before we transfer the weight.” Nadia pointed to the winch. “Oliver, can you keep tension on the remaining cable from the brake?”
“I can hold it. I can’t make it stronger.”
“You don’t have to. Just keep it from taking a sudden pull.”
They went back to the service floor. Oliver worked the brake lever until the cable’s vibration steadied under his hand. Otta set a pair of iron stops in the guide’s lower slots. Nadia took a long-handled maintenance bar from the wall and tested each stop against the stone. One seated. The other rocked.
“Loose,” she said.
Otta handed her a wedge. “That one was used for the shutter track.”
Nadia drove it into the slot with the heel of her palm and checked it again. The iron sat flush now.
“Ready?” Oliver asked.
“Lower it by a finger,” Nadia said.
Otta eased the brake. The counterweight descended with a grinding scrape. The surviving strand pulled taut. Oliver kept the lever steady, arms locked, while Nadia watched the gap between the block and the ledge.
“Stop.”
The block had settled against the first iron stop. The second took the rest of its weight with a shudder that passed through the floor. The cable slackened by a fraction.
Oliver held the brake in place. “That’s the ledge.”
“For now,” Otta said. She crouched beside the guide, inspecting the stone. “It’s holding.”
Nadia wiped grit from the second stop with her sleeve. “Now the chain.”
They took the shutter chain off the winch. Otta worked the old pin from the shutter bracket while Oliver fed the links down through a narrow inspection slot. Nadia held the lower end and guided it toward the counterweight’s lifting lug.
The chain fell short.
Its last link hung three inches above the lug.
Otta swore under her breath. “The counterweight has settled too low.”
“If we lift it, the cable takes the load again,” Oliver said. His grip tightened on the brake. The line gave a thin, high creak.
Nadia stared at the gap. The chain had enough length if they could turn the counterweight a little, bringing the lug closer. The block had jammed at an angle in the guide; one lower corner rested on the stop, the opposite side still wedged against the wall.
“Can we shift it sideways?” she asked.
“Not while it’s loaded,” Otta said.
Nadia looked at the maintenance bar in her hands. “We don’t need to lift it. We need to turn it.”
She slid the bar through a slot in the counterweight’s lower frame. Oliver watched her position it, then moved to brace the bar’s far end.
“On my mark,” Nadia said. “Only enough to clear the wall.”
Otta fed the chain down again. Oliver kept the brake fixed. Nadia leaned into the bar. The block did not move. She shifted her feet and pushed harder; the metal flexed against the frame.
“Mark,” Oliver said. “The strand’s pulling.”
Nadia held her position. A hot, familiar pressure stirred beneath her ribs. Her core answered the danger before she could stop it, a small bright weight pushing outward against her bones.
She let the bar take her weight instead.
“Now.”
Oliver pushed with her. The counterweight turned a fraction. Its corner scraped free of the guide wall, and the chain dropped onto the lifting lug. Otta drove a cross-pin through the links. Nadia checked it with both hands, then looked at Oliver.
“Transfer it slowly.”
Oliver released the brake one notch. The chain tightened. The iron stops held the block while the new line took weight. The old cable slackened. Its remaining strand hung in a loose curve, no longer the only thing between the counterweight and the drop.
Otta tested the chain with a short pull from the winch. It answered with a low clank from the stone pier.
“Again,” Nadia said.
Otta pulled farther. The counterweight rose a fraction, then settled back onto its stops. The chain stayed taut. The rail above them shifted toward its old alignment and held.
Oliver released the brake fully. The damaged strand sagged, useless but intact.
For a moment, the three of them watched the counterweight hang from the chain and rest against the guide stops. Nadia’s hands shook from the bar’s vibration. She pressed them against her thighs until they steadied.
Otta looked up at the rail. “That gives us a second support. It doesn’t make the rail safe for the train.”
“I know,” Nadia said.
“We’ll test the movement with the service trolley,” Oliver said. “Then we inspect the rail joint. If it holds, we bring the engine forward a short distance and check the chain under load.”
Otta nodded once. She pulled the shutter chain’s free end toward the service floor, then stopped when it reached the winch bracket. There was no way to reconnect it without taking it off the counterweight.
“The landing shutter won’t open again,” Nadia said.
“It shouldn’t open. The landing is gone.” Otta rested a hand on the abandoned winch. Her fingers stayed there longer than they needed to. “The chain has another job now.”
Nadia met her eyes. Otta’s expression had not softened, but she had stopped watching Nadia’s core. She watched Nadia instead, as if the work had changed the measure she used.
They ran the service trolley through the counterweight’s short travel. The chain took the pull. The guide stops stayed seated. On the second pass, the rail settled into alignment without the sharp jerk that had preceded the cable’s failing groan.
Oliver climbed out of the mechanism and checked the chain link by link. “It holds this movement. The rail still needs a load test.”
“Mercy,” Nadia said.
Otta pointed toward the maintenance shelf. “You can reach the engine by the route you used to come here. It’s still narrow.”
“We know,” Oliver said.
Nadia took the lead back across the shelf. They moved slowly, using the sound footing and checking each iron eye before trusting it. No one called the route safe. They called out what they could see, and waited for the answer before moving.
Mercy stood at the rail end with the cab light burning. Nadia reached the engine first and rested her palm on its warm casing. The repaired chain was out of sight behind the tower, but she could picture it: link against link, held to a stone pier by a pin they had tested with their hands.
Oliver climbed into the cab. “We bring it forward one wheel at a time.”
Nadia took the side position beside the approach rail. “And stop if the guide moves.”
He set the brake, then eased Mercy forward. The engine crossed the first joint. The repaired counterweight took tension through the chain, and the rail began to draw straight.
