Kinetic Rail Systems Mod lets you build real roller coasters with realistic physics in your Minecraft world. You can place track at any angle, create huge loops, and ride momentum-driven coaster trains. The mod handles gravity, friction, and speed calculations directly on the server so every player sees the exact same ride.

Features:
- Free-Form Track: Place track pieces at any angle, height, or pitch without sticking to the standard block grid.
- Custom Roller Coaster Trains: Build and color your own coaster cars using the in-game 3D voxel editor.
- Works with three track gauges and seven styles, including steel skeleton, wooden decks, and lattice frames.
- Adds lift hills, magnetic launches, and brakes that respond directly to redstone signals.
- Includes track sensors that measure speed, train presence, and train length.
- Includes mechanical track parts like switch tracks, drop elevators, tilt tracks, turntables, and lateral slides.
- Lets you build water rides such as log flumes, boat tours, river rapids, and splash-down coasters.
- Provides premade coaster elements like cobra rolls, zero-G rolls, and airtime hills.
- Features a stat tracker that displays your top speed, total ride time, and rider forces.
- Adds craftable steel support beams, wooden scaffolds, stairs, and fences to detail your builds.
- Includes an illustrated in-game guide book that covers every block, tool, and mechanic.
Track Machines:
- Switch Track: connects lines together using a sliding plate junction.
- Drop Track: moves whole coaster cars up and down like an elevator.
- Tilt Track: tips a flat platform forward into a vertical drop.
- Turntable: rotates a train around to face a new track direction.
- Lateral Slide: shifts trains sideways between parallel track lines.
Water Rides:
- Log Flume: sends log boats down water troughs with rushing foam and big splashes.
- River Rapids: spins an eight-seat raft down turbulent whitewater channels.
- Water Coaster: combines standard steel coaster drops with flooded splash-down sections.
How to Use:
- Read the in-game manual book to learn the basics of coaster construction.
- Craft coaster steel and place anchor points where you want your track line to go.
- Aim the anchors using a wrench and connect them together to make smooth curves or loops.
- Add a station, chain lift hill, or launch section powered by redstone.
- Place a coaster car on the rails and right-click to ride.
