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. Creative-mode focused (survival recipes are on the roadmap). 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.
• 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.

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.

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.

MineCoasters

A realistic-physics roller-coaster mod for Minecraft. Build off-grid spline track, ride momentum-driven trains through loops and inversions, launch them with LSMs, haul them up lift hills, and brace it all on steel supports.

Features

• Off-grid spline track from on-grid anchor blocks — full 3D orientation, so track climbs, dives, banks, and inverts with smooth cubic-Hermite curves.
• Momentum physics — gravity, rolling friction, air drag, and centripetal force through curves. Server-authoritative, so multiplayer rides stay in sync.
• Ride it — 4-seat cars with a rider camera that banks and rolls correctly through loops and corkscrews.
• Powered segments — tag anchors as lift hill, LSM launch, or brake and wire them with redstone. Build a full circuit: station → launch → climb → inversions → brakes → return.
• Multi-car trains with distributed-force physics; couple and decouple on the fly.
• Advanced elements — switch tracks, drop tracks, tilt sections, turntables, and lateral slides, all self-building multiblock machines.
• Many coaster types — narrow/medium/wide gauges; skeleton, box, triangle, wooden, I-Box, single-rail, wing, and inverted styles.
• Placeable prefab elements — auto-place loops, top hats, corkscrews, cobra rolls, dive loops and more, or capture your own as reusable blueprints.
• Ride cameras & photo screens — redstone-triggered on-ride photos.
• Ride Tracker — measured top speed, G-forces, airtime, inversions, and ride time.
• Steel & wooden supports, themed scenery blocks, paintable track in 16 colours, wood veneers, and a full in-game Manual.
