Meet your network
where it needs to be.

Build a light rail network with your existing trams. Open Light Rail between Road and Rail to find the tram depot, fenced track, configurable stations and the Underground Interchange.

01 / AT STREET LEVEL

Surface

Through stations connect their platforms via an underpass or level crossings at both ends. Termini have a landscaped forecourt. Stations align with nearby roads for easier placement.

GROUND LEVEL
02 / BELOW THE CITY

Underground

Choose a track depth of −18, −36, −54 or −72 m for a standalone station. The default is −18 m. A fixed station hall links both platforms to the street.

TRACKS AT −18 TO −72m
03 / ABOVE THE TRAFFIC

Elevated

Covered platforms on a concrete viaduct, with stairs from a central street-level entrance. Choose parallel or perpendicular alignment with the road.

Native connections

A dedicated track.
A familiar network.

Low metal fences give your line a separate right of way. Connect directly to ordinary electric tram track and road crossings, with native tram traffic handling.

Use the existing tram depot and vehicles. This mod adds station and infrastructure options; it does not include a new vehicle fleet.

02 / build to fit

Through the city.
Back from the terminus.

Run through services and terminating services at the same station with Turnback. Dedicated termini use a scissors crossover so trams can change ends without a turning loop.

Your platform length

Choose from five lengths in 20 m steps. Each track holds 35 waiting passengers per 20 m of platform, or 140 per track at 80 m. Enable Turnback on a through station to add a crossover at both ends.

Keep the line moving

  • Choose vehicles that fit the selected platform length.
  • Overlong vehicles can keep a terminus crossover occupied.
  • Select terminals or add waypoints for a specific track assignment.
  • Approach fences are optional above ground; elevated safety railings remain.
  • Stations, interchanges and fenced track unlock in 1925. The tram depot follows the base game’s availability.
03 / underground interchange

Connect lines
across levels.

Build one station with up to four underground levels. Passengers can change lines via internal stairs, and all platforms share a street-level entrance.

01 / LEVELS

One to four

The first level is 18 m below the surface, with another 18 m between levels. Each level has two tracks and through platforms with Turnback.

02 / PLATFORM LENGTH

40 to 120 m

Set each level to 40, 60, 80, 100 or 120 m. Waiting capacity follows the platform length on each track.

03 / ROTATION

0°, 45°, 90° or 135°

Set each level’s angle independently and rotate the entire interchange during placement.

04 / line management

Find your light rail lines.

The Light Rail filter in the native line manager shows tram lines serving at least one built-in or API-registered ULR station. Those lines also appear under the standard Tram filter.

Station API v1 — illustrated modular station framework
05 / built for creators

Your assets.
Our station logic.

Build a station pack with custom visuals and shared station logic. Choose an underground level for a standalone station, or combine underground, surface and elevated levels using the multi-level API.

STATION API v1 / BETA

A dependency you can build on.

Updates and extensions remain backward compatible with the documented v1 contract. If a change must break it, a new API version will appear alongside v1. Existing conforming v1 add-ons stay supported, without forced migration.

The core release number and API version are independent.

Read the Station API v1 documentation Build a multi-level station

You choose the appearance.

  • Exactly 20m platform and canopy modules.
  • Standard, custom or no optional shelter and decoration.
  • Trees, planters, benches, bins and platform lights.
  • Your mod ID and model namespace, in the shared Light Rail menu.

The core owns the network.

  • Two-track layout, terminals and stopping positions.
  • Terminus crossovers and reversing behaviour.
  • Fixed entrances, stairs, underpasses and pedestrian routes.
  • Structural supports, safety features and the fixed underground hall.

Custom components replace ordinary complete 20m sections. Short infills and fixed stair zones remain core-owned. The API validates the schema; creators must test their own model geometry and colliders.

06 / choose your starting point

Play it. Build for it.

The core is all players need. The developer kit and example mod are separate, optional downloads for station creators.

Before you build

A few useful
answers.

Will my API v1 station need a rewrite after an update?

Updates and extensions preserve the documented v1 contract. Breaking changes use a new API version alongside v1; existing conforming v1 designs remain supported. Internal builders and generated UI recipes are not public extension points.

Can I place my own stairs or change the number of tracks?

API v1 fixes two tracks, platform width and height, entrances, stairs and routes. Customise supported visual components instead. The underground hall is fixed.

Can I add a canopy to a surface station?

Yes. Supply an explicit 20m canopy model through the component API. Surface defaults have no canopy; elevated defaults include one.

What should I know about saves and other mods?

Keep the core and any asset mods enabled while their objects remain in a save. Other mods that modify the same construction interface may conflict.
