#On the Men Who Lay Iron Under Fire
Advance the rail. Then ask whether it was safe. — Bureau of War field instruction, disputed by the Guild of Rails
The Military Track Corps is the combat limb of the Guild of Rails, requisitioned by the Bureau of War whenever tactical rail must be laid, repaired, shifted, buried, blessed, spiked, lifted, or made to exist in ground currently receiving hostile attention. Its members are Track Engineers seconded from section houses and yards across the Dominion. On paper they are volunteers. On paper, many men are brave.
In practice, the Corps takes the crews Stationmasters (Unregistered) can spare, the crews Stationmasters dislike, the crews whose debts have acquired theology, and the crews whose skill makes them too useful to remain alive in a safe district. They lay rail to batteries. They repair bridge plates under bombardment. They keep shrine-locomotives moving. They crawl beneath the Sepulcher Locomotive while its chapel carriage is still hot enough to steam the mud from their sleeves.
The Corps is indispensable in the most insulting sense of the word: everyone remembers it only when the rail fails. A Warden-General may command an advance, a priest may bless it, a gun may wait with its barrel lifted like a saint demanding witness. The shell does not arrive until the track arrives. The rail must be walked into being by men with spike mauls, gauge rods, ballast forks, and the expression of labourers who know Providence has never once carried a sleeper.
#On Voluntariness and Other Polite Frauds
The Corps emerged from Guild secondments during the Gauge War and hardened after the Gauge Standardization Decree of A.S. 136 (Unregistered), when the Dominion discovered that a single measure did not make a single danger. Standard gauge allowed trains to move. War immediately asked why the trains could not move closer to the guns, closer to the trenches, closer to the breach, closer to whatever region of geography had begun screaming.

The Guild answered with technical caution. War answered with requisition seals.
A Track Engineer deferred from ordinary conscription may still find a red requisition tag folded into his pay docket. The tag names the theater, the duration, the hazard class, and the prayer recommended before departure. Refusal is permitted if countersigned by a Stationmaster, a War Transport Officer, and a Doctrine chaplain. This has occurred twice, both times for men already dead.
War Circular 88-R describes Corps service as “honoured voluntary technical assistance rendered by patriotic railmen.”
Clarified. Honour is present. Assistance is technical. Patriotism varies by pay arrears. Voluntariness remains a decorative classification, suitable for posters and widows.
Stationmasters perform the selection with the tender conscience of men choosing which finger to cut off. A veteran bridge gang may be protected for years because no one else can keep Irongate supplied. A troublesome Night Walker may be sent south after asking why demon-sign chalk has begun warming before sunrise. A crew with too many gambling debts becomes patriotically available. A crew that has seen too much becomes usefully distant.
#On Tools, Drill, and the Speed of Fear
Corps equipment differs from civilian rail gear only by abuse. Gauge rods are cut shorter for trench curves. Spike mauls are weighted for fast driving. Ballast sacks come pre-packed with lime, gravel, salt, and whatever Relics has powdered this quarter. Portable fishplates hang from belts like dull icons. Tool carts carry spare sleepers, crowbars, jacks, lanterns, water flasks, demon-sign chalk, folded track plates, and little red flags whose official purpose is signalling and whose common purpose is marking where someone’s hand used to be.
Training is short because the Corps prefers men who already know the work. The new lessons are military: lie flat when the whistle changes pitch, do not stand between rail and recoil, never argue with artillery about clearance, treat unexploded shells as scenery with malice, and if the ground begins singing through the sleeper, stop hammering and call the man with the blessed salt.
FIELD APPENDIX — CORPS DEMON-SIGN PROCEDURE If rail rings before being struck, mark with circle-and-line. If chalk darkens without flame, withdraw two paces. If sleeper bleeds, notify Relics. If rail repeats the name of a living crewman, ███████████████████████████. War notation: maintain schedule where practicable.
The Corps lays fast because slow crews die before they can learn. A temporary spur may be surveyed, graded, ballasted, spiked, tested, loaded, fired over, and torn up before the next dawn. Men learn to judge grade by bootsole and curve by shoulder pain. They sleep beside tool carts. They eat with blackened fingers. They curse in the clipped professional argot of men conserving breath for hammer strokes.
#On Batteries, Bridges, and Shrine-Locomotives
The ordinary Corps assignment is battery rail: short spurs pushed toward artillery positions so guns can feed faster than mules, carts, or the human spine can manage. These spurs run over bad ground, through shell holes, along trench backs, into fog pockets, across frozen marsh, beneath bastion walls, and once, at Bastion-Przemyśl, through a chapel whose parish priest objected until the first ammunition wagon arrived. The altar was moved three feet. The rail took precedence.
Bridge work is worse. A bridge under bombardment becomes a theorem in falling iron. Corps bridge gangs replace plates while rivets scream, brace trestles while current gnaws the piers, and measure deflection with hands that have learned to stop trembling only after the work is done. At Bastion-Irongate, where cliffs and river conspire like unpaid assassins, a bridge gang may spend six hours suspended above the Danube and return with enough living members to call the shift successful.
Shrine-locomotive work carries a separate misery. The Sepulcher punishes rail by existing on it. Its armoured carriages load curves like judgement. Its turret recoil walks bolts out of plates. Its chapel springs transmit sanctity downward in the form of axle strain. Before it arrives, Corps crews must certify the spur. After it passes, they must certify what remains. The second task is the honest one.
#On the A.S. 191 Southern Spur
The Corps acquired its most polished legend during the A.S. 191 Constantinople relief. The southern sky had failed its promised guardian: the Vigil Ark of Saint Uriel remained in drydock, authenticated, consecrated, grounded, and useless in the way only an expensive miracle can be useless. The Sepulcher Locomotive was ordered forward. The spur beneath it had other opinions.
Heat had buckled one section. Prayer-jam vibration had loosened a plate near the approach. A switch fused inside its housing in a posture one Guild report described as kneeling before Doctrine corrected the piety out of it. The Corps crew repaired it by morning. They worked inside shellfall, under soot rain, with water rationed for the boiler rather than men.
One man remained beside the ballast when the Sepulcher passed. Dead or sleeping, no one stopped. The conductor said someone would be sent. Nobody was sent.
War’s action abstract calls the track “emergency southern spur, Guild-maintained.” It lists rounds fired, relic damage, operational finding. It does not list the crew by name in the public version. Records possesses the names. The Guild possesses the names. I possess one: Matej Ors (Unregistered), junior hammer, twenty-three, assigned from the Sofia overflow yard, last seen lying with his left hand still wrapped around a spike.
An A.S. 192 commemorative engraving showed the Southern Spur crew standing upright beside the passing Sepulcher, caps removed, faces uplifted in patriotic awe.
Withdrawn from Guild houses after three copies were burned in section stoves. Corps crews do not stand beside passing shrine-locomotives unless they are dead, stupid, or already beyond correction.
#On Casualty and Pay
Eleven per cent per rotation: the figure appears in War ledgers with a calm little tail on the numeral, like a rat leaving a granary. It includes crush injuries, shell wounds, bridge falls, frostbite amputations, boiler scalding, derailment impact, demon-sign quarantine losses, and disappearances filed as terrain hazard because “the rail accepted him” has poor administrative tone.
The Guild pays hazard bonuses. War reimburses late. Families receive pensions according to status: full for confirmed death, reduced for disappearance, contested for contamination, delayed for cases involving Relics, and suspended if the body returns under its own power after burial. The last category is rare enough to be doctrinally interesting and common enough to have a form number.
The Corps drinks hard and keeps ledgers harder. Tool losses are recorded. Limb losses are recorded. Men lost in fog are recorded by nickname if the official roster lags. The unofficial rolls contain facts War would prefer converted into morale. Guild ink is stubborn.
#On Iron-Blood in Uniform
Long-service Corps men develop the same iron-blood reported among civilian Track Engineers, worsened by shelling and command. Teeth ache before cold-snap buckle. Palms prickle near hidden fracture. Dreams arrive with timetables. Some men can identify a damaged rail by stepping near it; some refuse to step near certain rails at all. The Bureau of Purity has investigated six times across the Guild and found no supernatural contamination. The seventh investigation will reach the same conclusion unless the rail signs its confession.
War dislikes iron-blood because it outranks orders at inconvenient moments. A Corps foreman may refuse a certification when a colonel demands passage. The colonel sees cowardice. The foreman hears a dead sound in the rail. If the foreman yields and the train crosses, War was correct. If the foreman yields and the train dies, War assigns no fault. If the foreman refuses and the front starves, War assigns plenty.
The Section 22-North derailment of A.S. 199 (Unregistered) sits in every Corps mind like a nail under the tongue: stress fracture noted in maintenance ledger, repair deferred by military order, thirty-seven dead, no fault assigned. The Corps learned the lesson War intended to hide. A signed order can bury a fracture. It cannot carry a train.
#On Present Use
As of A.S. 201, the Military Track Corps operates wherever the Sagittal Line requires iron in a hurry: ballast scars outside Bastion-Brest, Carpathian tunnel mouths near Bastion-Przemyśl, emergency approaches at Bastion-Sibiu, river plates at Irongate, sleep-fog warning spurs at Bastion-Shipka, and the blackened southern feeds of Constantinople. It is praised in War speeches, cursed in Guild taverns, overworked in every corridor, and remembered by the rail longer than by Strasbourg.
The Corps lays the line. War rides it. Doctrine blesses the arrival. Records files the delay. The Guild sends the bill.
