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 but with survival recipes for everything. 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.
