Universe: Train World

Overview

A man dies in our world and passes through purgatory into a strange new reality where civilisation exists aboard colossal, continent-spanning trains. Cities are not built on land — they are the trains, thundering endlessly across vast, untamed landscapes. He was supposed to arrive with a blank slate, his memories wiped clean like every other soul that crosses over. But something went wrong in the transfer, and he remembers everything: his old life, his death, and the fact that none of this should exist. Now he must navigate a world he doesn’t understand, with knowledge he was never meant to keep, while the powers that govern this place begin to notice.

Genre

Speculative Fiction / Fantasy Adventure with noir undertones

Tone

Warm but weathered. The world is strange and sometimes harsh, but there’s a current of dark humour running through it — carried by the people, the situations, and a narrative voice that finds humanity absurd and wonderful in equal measure. The method is Terry Pratchett’s: precise observation, compassion under cynicism, the mundane treated as extraordinary and the extraordinary treated as mundane. Humour from recognition, not gags. Satire of systems, not cruelty toward people. Earned emotional moments that land because the comedy built trust.

The narration stays close to Elliot but has the slight pull-back of an opinionated narrator — dry, observant, fond of the absurd. Every character, however minor, has their own logic and dignity. The world is played straight; the comedy emerges from taking impossible things completely seriously.

Themes

  • Identity and memory — who are you when you remember a life no one else believes existed?
  • Belonging — finding home in a world you were never meant to be part of
  • Class and confinement — the rigid social hierarchy of the train, from the luxury carriages to the open bunks
  • Second chances — what it means to get a new life you didn’t ask for
  • The mystery of passage — why do souls come here, and who decides the rules?
  • Compartmentalised knowledge — the train’s order is partly maintained by ensuring no one ever has the whole picture. The mystery of what powers the train is structural, not informational: the question isn’t what’s at the front but who decided that nobody should know. (See rules.md → Compartmentalised Labour Structure.) The view from outside sharpens it: the one civil servant who measures everything the train takes on at a resupply stop can confirm it never loads anything that could move it — whatever drives the Meridian, it brings its own. (See side story The Station Keeper.)
  • The honest record against the curated one — knowledge withheld by structure extends to the books themselves: records can be quietly omitted, not deleted and the totals smoothed over, by a faceless, patient hand. The only defence is an independent duplicate kept by someone the system doesn’t pay — so that a disagreement “exists somewhere.” (Side story The Station Keeper; cf. reveals.md M2/M4.)

Target Audience

Adult readers who enjoy character-driven speculative fiction with a mystery thread. Comparable titles: The City & The City (Mieville), Piranesi (Susanna Clarke), Snowpiercer, Railsea (Mieville). Readers who like worldbuilding that reveals itself through story rather than exposition dumps.

Series Plan

Multi-book series, connected. Each book is a self-contained mystery or adventure set aboard the trains, but an overarching thread builds across the series: why did the protagonist keep his memories, and what does it mean for the world? Book One is the arrival story and first case. Later books expand to other trains, other cities, and deeper into the cosmology of how this world relates to ours.

World Rules

  • Civilisation exists on colossal trains that span continents — far bigger than any real-world train. Each train is effectively a mobile city-state. In the wealthier sections, carriages are two-storey: ground floor corridors and services, private quarters upstairs.
  • Souls from our world pass through purgatory and are reborn here with no memory of their previous lives. The protagonist is an anomaly.
  • The trains stop briefly at station towns for resupply and maintenance, but never for long — stationary trains are vulnerable to bandit raids.
  • Each train has a rigid internal hierarchy enforced by the Conductor and their crew.
  • The land outside the trains is wild, largely unexplored, and dangerous. People who live off-train are rare outcasts. Bandits are a constant threat, both at stations and along remote stretches of track.
  • There is no magic system per se, but the mechanism of soul transfer and the nature of purgatory hint at deeper metaphysical rules yet to be understood.
