A flock of wyrmen tore back from New Crobuzon, scattered below the fast clouds and screeched at them. “They waiting! Thousands and thousands and thousands! Rows of ’em! No!”

Cutter and Rahul were racing on the eastern side of the tracks, eating the distance, so fast Cutter became hypnotised with it, until after a last turn of rocks the tracks converged at the end of suddenly bleak flatrock land, a stony pool and low marsh where there were wading birds as grey as the environs. At the end of the perfect perspective was a township of sidings, where the rails fanned. The smoke of workshops, the winter-dulled corrugate iron of train sheds, the sprawled terminus at the edge of New Crobuzon. Cutter sounded and heard Rahul sound too, become a single mass in the distance, one organism of pikes and cannon, clouded light reflected from thousands of masks, were the militia.

“Oh my gods.” Judah, where are you?

The troops waited.

“Where’s Judah?” Ann-Hari said. She was staring at the waiting men, miles off, and Cutter saw, good gods, he saw a challenge in her, a fight-light in her eye. A smile.

“We must have missed him. Come on, I swear he’s here…”

“You know nothing, don’t you, you don’t know nothing…”

“Godsdammit, Ann-Hari, we can find him.” Why are we looking? What will he do?

The train would come from the sheltering stone gulley out into that plateau with the New Crobuzon Militia waiting. Cutter saw the train. Come and come through, and the faces of all the Councillors pale when they saw what waited for them, but set with the knowledge that there was nothing else to be done. By the time they slowed the engine the militia would be on them. Nothing was possible except a last bravery, a tough pugnacious death. The knowledge would come over them, and the sweating and terrored faces of all the hundreds of Councillors on the train would toughen again, and the train would speed up. It would accelerate toward the enemy.

Come on, we taken the militia twice before, we can do it again, would come the shouts, lies that everyone would gratefully pretend to believe. Some would whisper to their gods or dead ancestors or lovers, kiss charms that would not protect them. They would shout, Iron Council! and For the Collective! and Remaking!

The Iron Council, the perpetual train, would howl, smoke streaming, the whistles of its cabin shrill, the sounds of its guns a tempest of bullets. The train would come into the zone of the New Crobuzon guns, and in bucking fire and the stretch and split of metal, in the agony shouts of burning dissidents, of fReemade, as hot death took them, Iron Council would end.

Gods, gods.

The Councillors rode back toward the train a few hundred yards. Cutter forced a slower pace. He watched the metal. Last chance. A mile, no more, into the cosseting of the stone surrounds. Again wyrmen overhead, but these ones speaking with different accents, these were city wyrmen come to greet the newcomers. “Come, come,” they shouted. “We’re waiting. Behind militia. For you.” They wheeled and went back toward some trackside machinery. Cutter rode.

“Ann-Hari.” A call from the edge of the gulch, twenty feet above. Cutter looked up and it was Judah.

Cutter let out a sound. He stopped his horse as Rahul stopped and he and Ann-Hari looked up. Judah Low was standing. He moved in agitation, craving their attention.

“Ann, Ann-Hari,” Judah shouted. “Cutter.” He beckoned hugely.

“Judah,” Cutter said.

“Come up, come up. What are you doing here? What are you doing? Gods, come up.”

Rahul’s great lizard weight could not take the incline, which slithered under him. He could only wait by the tracks as Cutter and Ann-Hari gripped handhold stubs of roots, ascended, stood, Cutter keeping his head down as long as he could so it was only at the very last that he raised his shale-grey face and looked at Judah Low.

Judah was looking at Ann-Hari with an opaque expression. He embraced her a long time, as Cutter watched. Cutter licked his lips. Cutter waited. Judah turned to him and with something at least half a smile gripped him too, and Cutter let Judah for a tiny moment take his weight. Cutter closed his eyes and rested his head, then made himself stand back again. They could see the tracks’ exit from the raised land.

They watched, the three of them, watched each other. Here he was, the tall thin grey-haired man Judah Low. What are you? Cutter thought. Around Judah were signs that he had been waiting. A water bottle. The obscure debris of his golem craft. A telescope.

In this place there was no one around them. The last cut before the city. Wyrmen went overhead again and circled, and shouted hysterical warnings as they went.

“What you been doing?” Cutter said. “What are you doing? They wouldn’t stop, Judah, they wouldn’t turn. I tried…”

“I know. I knew they wouldn’t. It doesn’t matter.”

“What happened? In the city?”

“Oh Cutter. Done, it’s done.” Judah was placid, cowish. He looked between Cutter and Ann-Hari’s heads at the curve of the track, in the direction from which the perpetual train would come. Looked back at them, back at the tracks. His attention switched ceaselessly.

“What’ll we do?” Cutter said.

“There’s nothing to be done, now,” Judah said. “It’s not the same now. The city… it’s changed again.”

“Why are you here, Judah?” Ann-Hari said. “What are you here for, Judah Low?” She was complicitous. They were smiling at each other, just. A little play in their voices. Even with the carnage to come, even having seen the militia, there was something still playful in her. She reached and touched him again and again, and he her. The thing between them was like an animal coiling from him to her and back. He looked over her shoulder and back at her.

“Judah!” Cutter shouted, and Judah turned to him.

“Yes, yes, Cutter,” he said. “Of course.” He was calming. “Why did you come here?”

“What have you done, Judah?” Cutter said. But there was a noise, and Judah gave a happy gasp just like a little boy and jumped on his toes, again like a boy. There were tears in his eyes. A smile and crying.

A wraith of smoke emerged a half mile off. The perpetual train. It wriggled up, the discharge, like a soot grub from a burrow, faster, slewing a tight turn through blasted barriers and coming closer. A wind came up before the train and pushed at their faces, Cutter and Ann-Hari turning to watch the lamps that rounded and shone weakly through the daylight, washed out the stone and the tracks, and the Iron Council came into the last of the cut.

No. Cutter did not know if he spoke aloud. He did not believe there were revolutionists hidden behind the militia. He watched and shouted aloud or in his head, as the Iron Council came through cleft stone and rolled at speed toward death. No.

The flared guard made into teeth, the engine a fetish head, carved with stories, hung with animal spoils, crowded with the toughest warriors, the biggest Remade, the cactacae with scramasaxes ready, roaring, feted by New Crobuzon refugees who ran alongside, who cheered desperately and threw confetti. The second engine, all its follow-ons, the whole tracktop town become militant, become its weapons, the Iron Council become a fighting city. Its wheels beat the iron, smoke gouting from its chimneys, everyone poised to fight, with no plan but the imbecile bravery of forward.

Uh uh, uh uh. Cutter heard it, the wheels, the clatter of tracks. He ran to the edge of the gap and shouted though he could not be heard. He saw that Judah was crying but still smiling, and Ann-Hari was smiling only. The train, faster than it had ever gone, went past Rahul, who waved his human and his lizard hands.
