The Passage (Soul Transfer)

How it works

When a person dies in our world, their soul passes through Purgatory — a liminal space of unknown nature — and is deposited into Train World. They arrive physically intact, at the age they were when they died, with no memory of their previous life. They simply are, as if they’ve always been here, with a vague sense of having come from somewhere but no specifics. Most people don’t question it; the feeling fades quickly.

Limitations

  • Memories are supposed to be completely wiped. The mechanism that does this is unknown — it could be a natural property of purgatory, or it could be deliberate.
  • Elliot’s retention of his memories is unprecedented (as far as anyone knows). The cause is unknown and becomes a central mystery.
  • There appears to be no way back. Death in Train World is permanent — there is no second transfer.
  • Not everyone who dies in our world ends up here. The selection criteria (if any) are unknown.

Who has access

Everyone in Train World came through the Passage, but no one remembers it. Elliot is the sole known exception. The Conductor may know more about the Passage than they let on.

The Trains

How they work

  • The trains are impossibly large — far bigger than any real-world train. Miles long, carrying thousands. They are powered by an unknown mechanism. The engine carriages at the front are restricted; very few people have ever seen what drives the train.
  • The carriages themselves are wider and taller than anything that runs on rails in our world. In the wealthier sections, carriages are two-storey: the ground floor holds corridors, communal spaces, and services (dining, shops, offices), while the upper floor contains private living quarters — quieter, more exclusive, accessed by narrow internal staircases. In the lower carriages, the extra height simply means taller ceilings and bunks stacked higher.
  • Trains run fixed loops across continents. The Meridian’s circuit takes approximately 14 months to complete.
  • Trains stop briefly at station towns along their route for resupply and maintenance. These stops are kept short — a few hours at most — because stationary trains are vulnerable to bandit raids. Crews work fast, passengers who need to board or disembark do so during these windows, and the train moves on. Between stations, the train maintains constant motion.
  • There are multiple trains in the world, each effectively a mobile city-state with its own culture, governance, and economy. The Meridian is one of the larger ones.

Limitations

  • The trains cannot leave their tracks. The track network is vast but finite, and no one knows who built it.
  • Trains occasionally break down or slow. This causes genuine crisis — a stationary train is exposed to bandit attacks, and the entire social and economic order depends on movement.
  • Communication between trains is limited to what can be exchanged at crossing points or via station towns.

The Compartmentalised Labour Structure

(Established in side story What Powers the Train.)

The fact that “the engine carriages are restricted; very few people have ever seen what drives the train” is not maintained by guards or locks. It is maintained by structure.

  • The maintenance crews on The Meridian are organised in non-overlapping sections along the length of the train. Each section’s workers know their own junctions, ducts, and pivots. They are authorised up to the forward boundary of their section and no further.
  • The crew immediately forward of any given section handles the next stretch. No worker has ever met the crew immediately forward of them. There is no overall map, no central worker, no foreman who oversees the whole chain. The chain extends, by implication, all the way to the engine.
  • Workers are paid by chit through cubby-holes. The chits arrive; the workers sign for them; the chits are exchanged for coin at chit-counters (e.g. Ekka’s, in Carriage 45). The path between the work being done and the chit being issued is not visible to the worker.
  • The result: nobody on the train has the whole picture, and the absence of the whole picture is not an accident. The system was designed this way, by someone, at some point, for reasons nobody alive remembers. It now runs on its own momentum.

This is a foundational architectural fact about The Meridian. It likely applies, in some form, to every train in the world. The “engine is restricted” line in the world rules is the surface; the compartmentalised labour structure is the mechanism beneath it.

Construction quirks

  • Some junctions on The Meridian were built with internal pivots that do not appear on the standard maintenance schematic. The same junction design appears in two places along the train (forward and middle), suggesting the train was assembled by a builder who liked to repeat junction designs even when functionally unnecessary. (Established in What Powers the Train.)

Society & Politics

The Carriage Hierarchy

Life on the train is rigidly stratified by carriage position:

  • First Carriages (front): Wealthy, powerful, politically connected. Private compartments, fine dining, guards. Lifetime tickets passed down through families.
  • Middle Carriages: Working class. Trades, services, administration. Decent bunks, communal facilities. Most people live here.
  • Open Carriages (rear): The cheapest passage. Shared bunks, no privacy, minimal services. Home to drifters, new arrivals, and those who’ve fallen through the cracks. Looked down upon but left largely alone.

Governance

  • Each train is governed by its Conductor, who holds absolute authority. The Conductor is not elected — the position passes through mechanisms that vary by train. On The Meridian, it’s unclear how the current Conductor came to power.
  • Succession & the “transition.” Power does not pass cleanly. The current Meridian Conductor took control ~30 years before Book One in events no one discusses; the previous Conductor is “not spoken of,” and the changeover (the “transition”) was disorderly enough that records were lost or damaged and the old Conductor’s collection was dispersed — which is how the gramophone left and later returned via the Lender (B1). Treat succession as opaque, semi-violent, and not constitutional: a Conductor holds power until they don’t, and what ends a Conductorship is one of the world’s buried questions. (Sealed angle — whether the Arrangement removes inconvenient Conductors — in bible-secrets.)
  • The reach of authority thins with distance. The Conductor’s writ is absolute in principle but, on a train miles long, strongest at the front. Toward the rear, enforcement is thinner and informal power fills the gap. This is why the open carriages are “looked down upon but left largely alone.”
  • The Conductor is supported by a crew of enforcers (uniformed, visible, generally polite, absolute), clerks (the administrative carriage; Casper’s world), and engineers (the restricted forward maintenance). Distinct from these is the Conductor’s aide (Albion) — no rank insignia, authority by proximity. Below the official structure, informal hierarchies emerge: carriage bosses, guild-like trade groups, and grey-market operators like Mr Fixer, who hold real local power the administration tolerates because it keeps the rear running.

Tickets

  • Your ticket determines your place on the train. Tickets are physical objects — heavy card, dark-red engraved border, embossed with the Conductor’s seal, hand-numbered, dated, and signed in iron-gall ink (see visual-reference). They are enormously valuable, and the document is the right — there is no separate register a lost ticket can be recovered from easily.
  • Tiers of ticket. Not all tickets are equal: a lifetime ticket (inherited, First Carriage) is a different object from a working passage (middle) or the cheap open-carriage chit-passage of the rear. A ticket names your carriage-class; moving up means a new ticket, not a stamp.
  • Forgery & its tells. Because the ticket is the right, forgery is the grey economy’s most dangerous and lucrative craft. The countermeasures are the embossed seal, the iron-gall signature (which ages and bites the card in a way ink doesn’t), the hand-numbering against the clerks’ ledgers, and the card stock itself. A good forgery fakes the look; it cannot easily fake the ledger entry — which is why corruption inside the administrative carriage (a clerk who will enter a forged number) is worth more than any forger’s skill, and why the records are where bodies are buried (Casper’s whole arc).
  • Being ticketless is a serious offence — Elliot’s opening predicament. Punishment ranges from forced labour to being put off at the next station town. The ticketless have no rights and minimal protection; “ticketless” is both a legal status and an insult.
  • Tickets can be bought, earned, inherited, or — in the grey economy — forged, stolen, or traded. Destroying a ticket (or losing one) is catastrophic: it can unperson you, which makes tickets a tool of coercion as well as commerce.
  • Being put off, from the receiving end (the “alighted”). (Established in side story The Alighting.) When the punishment is being set down at a station town, the ticketed are shipped on “to somewhere with a magistrate”; the ticketless are simply got down and the train goes on. Certain towns have learned to absorb these expellees as labour and have a recognised word for them — the alighted — with attendant institutions: a ledger of the alighted, a shed, an expectation of work, a known first-winter attrition. A receiving town stays strictly neutral in a passenger’s dispute with the train, because the train returns and a town the trains stop trusting dies of it. The mercy is real, small, and self-interested. (Bauch’s Crossing, locations, is the established example.)

Economy

Currency

The trains use chits — small worn metal tokens (roughly the size of an old shilling) issued by each train’s administration, stamped with the train’s seal (The Meridian’s is a stylised arrow over a circle; see visual-reference).

  • Issuance & trust. A chit is only as good as the administration that issued it, which is why a Meridian chit is worth little on The Calloway except at a crossing. There are no large denominations — chits are a low-value, high-volume currency for daily life; large value moves as goods, favours, or tickets, not stacks of chits.
  • Exchange at crossings. When trains meet (~every 7 years), cross-train exchange rates are struck fresh each time — there is no standing rate, because the trains don’t interact between crossings. Rates are negotiated by the administrations (and shadowed by grey-market operators) based on each train’s recent fortunes, what each needs, and bluff. A crossing is, among other things, a brief, intense currency market.
  • The cubby chain. Wage-chits (e.g. maintenance) are delivered impersonally through cubby-holes and cashed at chit-counters (Ekka’s, Carriage 45). The worker never sees the chain between work done and chit issued — the small daily face of the train’s compartmentalised machinery.
  • Barter is as common as chits in the open carriages, where coin is scarce; favours are tracked socially (Aini’s rule: work out what someone did for you before you thank them).

Earning a Living

Life on the train runs on a gig economy. Passengers who need to eat and drink either barter what they have or earn chits through work:

  • Hauling and moving — shifting cargo, supplies, and materials between carriages. Always needed, always available, poorly paid.
  • Farm carriages — semi-open carriages towards the rear of the train where livestock is kept and crops are grown. Tending animals, mucking out, harvesting — hard, unglamorous work that keeps the train fed.
  • Maintenance — repair work on the train itself. Fixing pipes, patching walls, clearing blockages. Skilled workers earn more; anyone can sweep.
  • Services — selling to other passengers, like Birdie running the tea car. Cooking, mending clothes, barbering, message-running (Jem and Pip’s trade). If someone needs it, someone sells it.
  • Skilled trades — instrument repair (Mr Plum), mechanical work, carpentry. These command better rates but require tools and reputation. There is no welfare system. If you don’t work, you don’t eat — unless someone in your carriage shares, which in the open carriages, they often do.

Trade

  • Trains trade with each other at crossing points and with station towns during resupply stops.
  • Key trade goods: food (grown in the farm carriages or sourced from station towns), materials, manufactured goods, information, and passage itself.
  • A thriving grey economy exists in the lower carriages — Mr Fixer operates within this space, brokering favours, goods, and information.

Station-town tariff & the keeper’s countersignature

(Established in side story The Station Keeper.)

  • A station town tolls the passing train for water, coal, standing, and right-of-way. To assess the toll, the town’s keeper countersigns the train’s declared freight manifest against her own independently-made car-tally (chalked by walking the stopped train). The two records — the train’s and the town’s, made by people who do not work for each other — must agree before the keeper puts her iron-gall signature to the toll.
  • Consequence worth holding: a station halt is, as far as anyone in-world knows, the only point on a train’s whole circuit where the train’s account of itself is checked against a record kept by someone the train does not pay. Keepers also hoard their own duplicate of every manifest for decades. This is the one external audit-point in the world — structurally able to notice curation an insider never could (a line omitted, not deleted; totals re-footed clean). The Meridian’s relevant halt is Tarnhalt (see locations).
  • Tariff classes: freight is tolled by chargeable weight; bonded, sealed, through-carried goods are declared-as-aboard but not landed, and pass at nil tariff — which trains the keeper’s eye away from them, so an unbillable line can ride a manifest unexamined for a very long time.

The Grey Economy (specifics)

The unofficial market that runs alongside (and through) the official one, concentrated in the rear where the Conductor’s reach is thin. It is tolerated because it keeps the open carriages functioning and because the administration quietly uses it.

  • What it actually trades:
    • Information — the highest-value commodity. Who arrived, who owes whom, what the clerks are quietly recording, what the Gazette won’t print. Birdie’s tea car is the open exchange; Fixer’s network is the brokered one.
    • Forged & traded paper — tickets and the corruption that makes them real (a clerk who will enter a number); see Tickets.
    • Smuggled & diverted goods — items that “fell off” a manifest, First-Carriage luxuries moved rearward, drink, off-ration food.
    • Passage objects — the dangerous high end: collectors (the late Drummond’s milieu, the Lender) prize objects like the gramophone and the tuning fork without understanding them (see reveals M6). This is where the grey economy brushes the cosmology.
    • Favours & protection — the real currency of the rear, tracked socially and called in later.
  • How it’s enforced: not by law but by reputation and reciprocity. Operators like Fixer hold position through a mix of usefulness, owed favours, and the implicit threat of withdrawing both. Carriage bosses keep order the administration doesn’t reach.
  • Its relationship to power: symbiotic. The administration could crush it but doesn’t, because the grey economy absorbs problems (housing new arrivals, moving goods, keeping the peace) that the official structure can’t be bothered to. The Conductor’s office occasionally uses a Fixer-type for deniable work — which is precisely how Elliot is hired (B1) and retained (B2/B3).

The Gramophone (Book One MacGuffin)

The gramophone was lent to the Conductor by an outside figure — someone powerful and dangerous, not to be crossed. It was loaned for a concert being held in the First Carriages to bring some culture to the guests. The gramophone goes missing during preparations, and the Conductor needs it back before its owner comes looking for it. The stakes are personal and political: losing this item means losing face with someone who does not forgive. The thief is chased through the train, but when caught, doesn’t have it. The gramophone was hidden inside a life-size replica cake of the gramophone itself — a showpiece being made by the patisserie’s assistant as part of the concert party decorations.
