Description
Build complex or simple train tracks in minutes, then preview them instantly. Trains can be customized for any setup, look or feel.
Tracks are spline based, allowing you to setup complex meshes quickly. Also included is the terrain train track for quickly building tracks across uneven terrain.
Track triggers allow you to have trains or carriages fire events in the game world. Use triggers to create junctions that change, or level crossing barriers that lower as a train approaches, or leaves.
The mine cart comes with a custom jump trigger that uses built-in events to extend the base carriage, allowing the mine cart to jump, rotate and scale into the air for comic effect.
Each carriage can detect obstacles on the track and respond accordingly, some can stop and wait for it to move, others can ignore it and keep on going.
End of track options give you the ability to define how the train or carriage responds to the end of the track; stop, reverse direction, derail, …, or add your own custom response.
The system comes with a pre built mine cart, modern train engine, and two example carriages.
The system is highly customizable and comes with documentation, examples and videos.

Features
General:
- Pre built trains: Modern engine, flat car, box car and mine cart
- Highly detailed example maps broken down by train / track category.
- All blueprints commented and with helper comments on where to extend sections
- Documentation provided for all major blueprints including detailed descriptions of every component, macro, function and variable
Train Carriage:
- Select a track in the world and the train carriage (or entire train if this is parent) will snap to it
- Supports one or two bogies
- Customize all meshes and entire look. Comes with offsets for all meshes relative to position on tracks.
- Bogie distance, wheel animation playback speed are all customizable
- Multiple end of track options (what the train does at the end of the track) including; derail, reverse direction, stop, attempt to stop, warp to original position
- Easy to add new end of track options if you desire
- Start inverted on track (if the train carriage should be flipped)
- Highly configurable engine / physics: friction, gravity, mass, acceleration, deceleration as well as max speed, min speed
- Ability to disable realistic speeds and use constant speed, E.g. creating a roller coaster or conveyor belt
- Ability to select the starting direction of travel
- Select carriage type; Engine will be able to move itself while a standard carriage won’t move without an engine or force moving it
- Impact collision; If enabled the carriage will knock back obstacles in front of it (min size can be customized / large objects can slow the train / carriage down)
- Sensor in front of the train can detect obstacles on the track
- Obstacle responses dictate how the carriage responds, E.g. it can stop and wait for it to move, just ignore it and crash into it or not do anything.
- Easy to add new obstacle responses to your setup
- Collision filtering, E.g. Carriage will ignore the player but derail if it hits a static mesh
- Plow strength; Impact force used to knock objects away
- Flag the carriage so it never derails
- Customize the derail force, set a low force for small crashes, or a large one for more dramatic ones
- Collision ignore list, add any actor you want to the collision ignore list
- Timed collision ignore list, add any actor and a time to the list and it will automatically be removed from the list when the supplied amount of time has passed
- Ability to dampen the derail force that’s passed down to children
- Quickly build trains with the parent / child select
- Parent carriages pass their settings down to the child carriages by default (this can be disabled if needed)
- If something happens to a child carriage (E.g. end of track) it will ask the parent how to handled
- Ability to specify how far apart child and parent carriages should be
- Distance checks can be enabled and the child can disconnect from the parent if the distance is too great
- Customize the parent lerp speed. Child will try and match the parent speed, the lerp value specifies how close it will match.
- By default all carriages come with the Lean Effect and the Roll Effect (the mine cart has a custom jump effect)
- Lean Effect, ability for the carriage to lean on or out of a bend, creating a cartoon lean effect
- Lean effect thresholds and limits can all be customized
- Roll effect is used to derail a carriage if it goes around a bend that’s too sharp.
- Roll effect threshold can be customized as well as the check performed, for example you can have it ignore Pitch and Yaw but derail on Roll only.
- Debug strings have been left in place, but can be disabled with a single option
- Add as many custom bogies to a carriage as you need for a custom setup
- Events for post update to carriage as well as enter and leave each section of track
Mine Cart
- Mine cart is an excellent example of a single bogie carriage
- Also an excellent example of using events to customize the carriage and implement custom effects (jump trigger)
- The mine care features a jump effect that’s applied to the carriage and can modify the scale, location and rotation of the carriage body or bogie
Connection Tool
- Auto rebuilds and detects invalid connections between tracks
Debug Tool
- Debug functions such as rendering bogie positions or carriage hitches stored in one debug blueprint so main blueprints aren’t bloated
- Print all connection info about a track or connection points
- Print / render all bogie names for selected carriages
- Render trigger regions for selected tracks
- Render sensor bogie in real time
- Render carriage hitches in real time
- Delete all trigger regions from a track
Tracks:
- Tracks can be joined together to form complex or simple track layouts
- Spline based mesh building
- Any spline added to track blueprint will be handled as track spline (unless ignore tag is added)
- Mesh building for spline can be disabled so merged actors or meshes can be added in place
- Up direction can be set to create handing or twisted track
- Connection arrows to visually indicate if connection made to another piece of track
- Customize the connection distance (how far away the end point of another piece of track must be to be connected)
- Notifies any carriage / train attached to track about editing so it can update
- Ability to ignore other tracks in world when building connections
- Ability to force track to use track connection (if multiple exist)
- Ability to pick connection at random (if multiple exist)
Terrain Track
- Same as an ordinary track except it auto adds the spline points and uses line traces to conform to the terrain underneath
- Best used with actor merging to build tracks quickly over uneven terrain instead of hand modeling everything
Triggers
- Attach to a single spline or all splines on a track
- Customize the trigger radius
- Comes with multiple events to customize the trigger behavior
- All trigger fire events have the bogie as well as the parent carriage passed into them
- Options to trigger once, reset, timed reset, trigger once per carriage, delay on fire
- Trigger map comes with four pre built triggers to provide detailed examples
