MineCoasters — real roller coasters for Minecraft

Build real, physics-driven roller coasters on smooth, free-flowing track. Place anchor points, aim them with a wrench, link them into flowing curved track at any angle — then drop a car on and ride. Momentum, gravity, friction and drag are all simulated: what your layout can do is decided by physics, not by rails snapped to a grid.

For Minecraft 1.21.1 on NeoForge. Plays in creative or survival. Works in singleplayer and multiplayer — physics is fully server-authoritative.

Free-form spline track

• Track goes anywhere: any height, any bank, any pitch — loops, corkscrews, overbanks, beyond-vertical drops.
• Three gauges (narrow / medium / wide) with matching 4-, 8- and 24-seat trains, and seven track styles — classic steel skeleton, Mack-style triangle lattice, B&M box spine, wooden (real plank decks + walkways), RMC-style IBox, square lattice, and a cheap-and-cheerful wild-mouse "simple" style. Any style pairs with any gauge.
• Single-Rail (RMC Raptor style) with its own straddle car, and an Inverted toggle that flips any layout overhead so the cars hang beneath.
• Layout helpers: one-click Smooth fairs the kinks out of a whole layout, and Auto-bank banks every turn for the speed you actually rode it at.
• Paint everything in all 16 dye colours; re-skin wooden track with 11 wood veneers.

Drive the train

• Lift hills with animated chains, LSM launches, and brakes — all redstone-controlled, with per-section speed, strength, acceleration and friction tuning.
• Track sensors (presence / train length / speed output) and a sound machine for station ambience and ride music — build stations, block sections and auto-dispatch with plain redstone.
• Multi-car trains with a coupler tool; ride any seat, with a smooth quaternion ride camera that handles inversions properly.

Machines

One block builds the whole thing, docks and all — then redstone runs it:

• Switch Track — a transfer-table junction with a sliding plate, and an angle slider for each leg: straight-and-curve, a symmetric Y, or two curves of different sharpness.
• Drop Track — a vertical elevator that carries the car between levels.
• Tilt Track — holds a train flat, then tips the whole platform into a vertical drop.
• Turntable — spins a whole train to face a new line (or 180° for shuttle coasters).
• Lateral Slide — a transfer table that carries trains sideways between parallel lines.

Design your own cars — including spinners

The Cart Workstation is a full 3D voxel editor: build cars from eighth-block RGBA voxels (glass canopies included), place seats anywhere, preview against real track, and share designs as files. Every car in the mod is a voxel design, so anything can be replaced or remixed.

Stamp a design onto Coaster Car items and run as many different cars on one layout as you like — a red train, an orange one and a green one circulating the same track, or a train with a distinct nose car. Stamped cars keep their own size, so a train of mixed cars spaces itself correctly, and the design follows the car through a crash and back.

Add a Bearing and your design becomes a spinning car with real free-bearing physics — cornering and launch forces whip a lopsided tub through tight bends, riders count as weight, and vertical bearings swing like suspended gondolas. Ready-made wild_mouse and S&S 4D designs are included.

Water rides

• Log Flume, wide Boat Ride, and River Rapids (a spinning, bobbing 8-seat raft) — flowing troughs, rushing whitewater foam, waterfall roars on drops, and big speed-scaled splashes.
• The Water Coaster is a real steel coaster that floods only the sections you choose — dry drops into splash-down troughs and out again, Mack style.

Designer tools

• Element Placer — 21 parametric prefab elements placed in one click, from banked turns and airtime hills to Norwegian loops, zero-G rolls and cobra rolls — plus typed, ready-to-run lift hills, stations and launches. Realistic heartlined rolls, exact dimensions, and a live ghost preview.
• Blueprints — capture any hand-built section as a reusable element and share it as a file.
• Ride Tracker — a stats tablet: ride time, top speed, airtime, and honest rider-felt G-forces, plus automatic detection of drops, airtime hills, helices and inversions.
• Ride Cameras — redstone-triggered on-ride photo cameras feeding photo screens. Real on-ride photos of your actual trains and riders.

Supports & scenery

Steel support beams (with ladders and bracing), wooden support planks with a dedicated Plank Saw, carveable wooden scaffolds that track passes through, plus steel platforms, stairs, fences, rope fences and concrete footers — in every colour.

Survival

Every item is craftable, and building consumes what you've made.

Smelt Coaster Steel from iron and coal, bind Fortified Sticks from ordinary sticks, and work up to track, supports, scenery, tools and machines — all in a normal crafting table. Steel comes out bare-metal gray and takes any dye the vanilla way: eight of a colour around one dye.

Track and supports cost by length, so spacing your anchors for a smooth curve never costs more than spacing them sparsely. Pull track up with the Linker and the pieces come back. The Element Placer tells you the price of a loop before you place it.

Prefer to build without the bookkeeping? Creative mode is untouched — nothing is ever consumed there.

The Manual

Every player starts with the illustrated MineCoasters Manual — chapters, a clickable contents page and an illustration on nearly every section — covering all of the above in-game.

Multiplayer: fully supported; physics runs on the server, so everyone sees the same ride. Modpacks: permitted — see the licence. Found a bug or have an idea? Use the issue tracker.
