"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.
