The Meridian — Carriage Map & Layout

A working schematic so chapters place things consistently. The train is miles long with dozens of carriage classes; this pins what the books have actually established and marks the rest as approximate. When a scene needs a carriage number, take a pinned one if it fits, or an approximate one from the right band — and log any new fixed number back here.

For the texture of these spaces see locations; for how they connect see locations → Couplings, Gangways & Circulation; for the look, visual-reference.

Orientation (read this first)

• The engine is at the front. Carriage numbers climb toward the rear. Low number = forward = toward the engine = wealth, warmth, power. High number = rearward = open carriages, farms, cold, cheap passage. (motifs “forward/warm”.)
• “Forward” and “the front” carry weight — they point at both the social top and the unknowable engine. Use the words deliberately.
• The sub-floor service tunnels run beneath every carriage, with their own forward/rear logic and their own restricted boundary (FH-7). They are a second map under the first.
• Section boundaries are soft. The order below is canon; the exact carriage where “First” becomes “middle” is not pinned — keep it fuzzy on the page.

Scale baseline (read before staging any scene)

The public carriages are big; the service ways are small, tight, and never a route.

• Open carriages are steerage decks: barn-wide, high-ceilinged, three-high bunk rows with several aisles; the far end lost in stove-smoke and laundry. You can lose sight of someone in Carriage 74.
• Middle carriages: solid floors, vestibules between cars, room for a market crowd.
• First Carriages: two-storey; wide ground-floor corridors, dining cars, lounges, commercial-scale kitchens; private upper floors reached by narrow internal stairs (chokepoints, often with a stair-keeper).
• Service passages (behind First Carriages rooms): single-file, shoulder-brushing — two people can’t pass.
• The sub-floor: a ~4 ft crawl — hands and knees or bent double.
• There is no parallel corridor network, nothing crosses at right angles, and there is no upper floor in the middle or open carriages. “Caged bulbs / gritted mesh / grating” belong to service ways and working spaces, not to living carriages or First.
• Chases and crowds happen in the big spaces; service access is a brief squeeze.

[ REAR COUPLING ]  ← where Elliot was found, B1

First Carriages (~1–20) — front, wealthy, two-storey

Polished brass and velvet; carpeted corridors that swallow footfall; private upper-floor quarters by internal staircase; dining cars with real china. Lifetime tickets, guards, political weight.

• Carriage 3, Carriage 7 — front First Carriages (referenced; wealthy).
• Carriage 6 — two-storey residential (Above Stairs): upper corridor of private quarters (Ferrers, Carrow, Quayle, Tennant and four more) reached by a single fourteen-step internal stair kept by Mossop; service passage, bench and bell-board on the ground floor; a kitchen two carriages back.
• Carriage 7 — ground-floor service quarters (cleaners; Portis, B1).
• Carriage 9 — two-storey: the Meridian Gazette office on the ground floor; wealthy private compartments above (Drummond’s compartment, B1).
• Carriage 11 — the Gazette press is printed here every 14 days.
• Carriage 12 — the concert rooms (B1): the ground-floor storage room where the gramophone was kept (keyed door to the corridor; a small painted-shut back door into the service passage), with the concert hall and patisserie/kitchens close by; the kitchens (Carriages 13–14, with the dining saloon forward in 13 and the patisserie at the kitchens’ forward end) have an ice locker beneath their floor — a ~4 ft cold void, block ice in sawdust, floor hatch from the service passage. Also a front carriage with good windows; the window bench where Vashti watches the landscape (B3 Ch1/18). Public-access.
• Carriage 14, Carriage 18 — First Carriages area.
• Carriage 19 — Madame Vetch’s antiques shop (B1), where the tuning fork resonates near Elliot.

Front-middle / Administrative (~20s) — the bureaucratic centre

Quiet, orderly carriage(s) “near the front-middle” where the Conductor’s clerks manage tickets, manifests, passenger rolls, dispute records; the Conductor’s office adjoins.

• The Administrative Carriage — Casper Noll’s workplace; deep records rooms.
• Vashti’s Office — a small front-middle room given to her late in B3 (reward + leash).
• Carriage 28 — front-middle (referenced).

The middle carriages (~28–55) — working class

Trades, services, markets, bunk-and-berth homes. Where most people live.

• Carriage 31 / Carriage 32 — the FH-7 sub-floor boundary sits in the bulkhead between them (see Sub-floor below).
• Carriage 35, Carriage 38 — middle (B3).
• Carriage 40 — middle (B1).
• Carriage 41 — Vashti Kade’s home (B3): semi-private bunks, durable arrangements, night-shift haulers and menders.
• Carriage 44 — Della Roan’s home (B7): middle-carriage berth of the missing cartographer; where twenty years of network maps were hidden in coat-linings and bunk-boards. Her older berthmates persist as minor figures.
• Carriage 45 — Ekka’s chit-counter at the back, paying out maintenance/engineering chits.
• Carriage 47 — the kitchens (Head Forward): a manufactory, not a galley; fills 47 and spills into the carriage either side; feeds everything from the tea car forward to the edge of the First Carriages (which keep their own). A wide, low stock door aft where the forward draft is received by the clerk Lusk.
• Carriage 52 — middle (B1).
• The Maintenance Workshop — a low carriage between the freight cars and the laundry; Kettering’s middle-section crew bases here. (So: freight cars + laundry sit in this mid-to-rear band.)

The Tea Car — the crossroads (~mid-50s/60)

Birdie Wren’s carriage, sited between the open carriages and the working middle so the clientele is mixed. The information hub.

Open / lower carriages (~55–74) — cheap passage

Three-high bunks, hanging-sheet partitions, shared stove-plates, no privacy; drifters and new arrivals.

• Carriages 59, 60, 61, 62, 67, 68, 69, 71, 73 — open/lower band (referenced across B1/B2).
• Carriage 74 — Elliot’s first home; Fixer and Plum hold prime bunks near the rear wall.

Farm carriages — rearmost

Semi-open, slatted-side carriages with livestock and crops; produce hauled forward to the middle kitchens and markets. Towards the very rear, ahead of the rear coupling.

• Crop carriages — the long green run of the farm section (troughs, rigged lighting, rafters full of pigeons); the first crop carriage carries the Office notice board for the back of the train. (Head Forward)
• The stock carriages — the last three carriages on the train: goat carriage, hen carriage, pig carriage, in that order, front to rear, then the rear coupling. Numbers deliberately unpinned. (Head Forward)

The rear coupling

The back end, where Elliot first arrives/ is found in B1. The open carriages’ threshold to the outside and the wilds.

The sub-floor: service tunnels

A second network beneath every carriage — crawl-spaces ~4ft high, caged bulbs, gritted-mesh floors, pipework and pivots. Organised into non-overlapping maintenance sections along the train’s length; warmer forward, cooler rearward.

• FH-7 (Hatch Forward Seven) — in the bulkhead between Carriages 32 and 31, the forward boundary of the middle-section crew’s authorisation. Ghosted plate: FORWARD OF THIS POINT — ENGINEERING ONLY. Unlocked — the boundary is structural, not enforced.
• The forward tunnels — beyond FH-7, running under the front third of the train (≈ carriages 31→1) and on toward the engine. Maintained by a separate chain of workers the middle crew has never met. (So the First Carriages live above a sub-floor they have no access to — the closer to the engine, the more restricted the maintenance, which is the compartmentalisation theme made physical.)
• Bellan’s Workshop — set into a widened section of the forward tunnels, ~4 carriages forward of FH-7 (beneath ≈ Carriage 27).
• The chain extends, by implication, all the way to the engine. No one has confirmed where it ends. See rules → Compartmentalised Labour Structure and side-stories/canon-notes.

The Calloway — layout (less mapped, looser)

Book Two’s train. Numbered like the Meridian, but its classes are marked by colour-banded sections rather than implied by number, and displayed openly.

• Colour bands (forward → rear): red (forward, high status), gold, green, blue (rear). Banners at the windows announce class before the carriage number does.
• Sable’s Court — a wide carriage near the front; half throne room, half dinner party.
• The Record Hall / archive — bigger, louder, more oral than the Meridian’s; in the green section.
• The gold market — where Mette’s bread alcove sits.
• Carriage 27, Berth 8 — Maren Toll’s berth (mid-section; curtain not door); entered by the killer via the Berth 7 maintenance hatch.
• Carriage 14 — where Toll originally boarded via the crossing-point gangway seven years earlier.
• The Crossing Platform — the parallel-track stretch where the gangways are thrown; the four-hour clock of B2.

(The Calloway is intentionally less pinned than the Meridian — flesh it out as B2 work demands, and log fixed points here.)
