A guide to the systems, written from the game's own rules.
Building
Track, stations and the vehicles that run on them.
- TrackLevels, flyovers, junctions and single track — how trainsworld's track works, and why your line is full.
- StationsPlatform length, upgrades, terminals and passages — how stations decide who can reach your network, and how fast it moves.
- Trains & vehiclesCars, trams, buses and boats — what capacity costs, how crowding changes demand, and when to lengthen instead of adding.
Running a network
Schedules, demand, fares and the money.
- Lines & schedulesStops, lap times, headways and demand periods — how to work out how many trains a line actually needs.
- DemandHow trainsworld decides who rides — bubbles, purposes, effective time, crowding and the five periods of the day.
- FaresThe fare curve, transfer fares, mode multiples — and why a fare is really a number of minutes.
- MoneyWhere trainsworld's money comes from and goes, how loans work, and what the ledger is telling you.
The world
