Cutter stumbled, and behind him he heard Judah muttering, heard Judah repeat the two-part rhythm, the repeating beat of the train. He was singing along with the train, and there was something expectant in him. Cutter leaned over, looked down on the train and the Councillors preparing for war, their last war, for their city again. He saw ahead of them a strange pattern of obstructions between the ties, nothing heavy enough to derail or damage the engine, but a precise set of interruptions, looking from above like the points of a pictogram, over a few yards of track.

"Uh uh uh uh, " Judah said, and below in time sounded uh uh, and the front of the Iron Council passed over a mechanism Cutter had seen, that he had thought a signal relict or something half-finished; and as the wheels touched it and it clattered, it beat into motion, and Judah gasped and dropped to his knees. His skin stretched; the very meat of him seemed bled away. Cutter saw the force of his cathexis, the yank of energy.

He heard the syncopation of the train and of something else now, a complex interfering, percussion in antiphase. Iron Council tripped the switch that Judah had laid for it and the circuit he had left went live, siphoning force from him, and only Cutter could see. Cutter watched Judah blink and gasp.

The little blockade between the tracks, which Judah’s first shout had stopped Cutter or Ann-Hari seeing, wedged in the shingle, propped on crossties-a blockage of pins, of metal rods, of blocks-was pushed over by the Iron Council. Each piece landed hard, onto the contacts Judah had laid, and their strange precise order, their materials, made each of them fall with its own sound. They combined into a careful and exact music of breaking, snaps and tolling iron that added to the flawless beat of the train; and for seconds, for a snatch of time, there was pulse-magic, a palimpsest tempo, and in that moment of complexity, each accented block of noise intervening in time, cutting time into shape so that as the huge hunter’s head of the Iron Council emerged from the rock folds and synclines into open land the moments themselves were hacked by the noise, axed into shape, an intervention through the mechanism that sucked energy from Judah Low, the great self-taught somaturge of New Crobuzon, and crude, vigorous, ineluctable, the precision of that parcelled-up time reshaped time, was an argument in time,

reshaped the time itself, and made it
