Splinecart is a rail and minecart overhaul that focuses on bringing smooth, flowing motion to Minecraft’s transportation and coaster systems. Instead of relying on the game’s usual rigid, block‑to‑block rail angles, Splinecart introduces a spline‑based track system that allows rails to bend, curve, and transition naturally. The result is minecart movement that feels closer to a real roller coaster, scenic railway, or theme‑park ride, with carts following the track in a continuous arc rather than snapping between straight segments.

The mod is built around a simple but flexible workflow. Players place Track Ties, rotate them to set direction, and then connect them using a Track item. The mod automatically generates a smooth rail path between the ties, respecting the orientation and spacing the player sets. This makes it possible to create sweeping turns, long spirals, gentle slopes, or tight coaster‑style elements without fighting Minecraft’s usual rail limitations. Vanilla rails still serve as the entry and exit points, so Splinecart can be integrated into existing worlds and builds without replacing everything.

Splinecart includes several specialized track types that expand what minecarts can do. Regular Tracks behave like standard rails but with the benefit of smooth curvature. Chain Drive Tracks act as powered lift segments, pulling carts upward at a steady pace regardless of slope. Magnetic Tracks allow for controlled acceleration or braking using redstone power, making it easier to manage speed throughout a ride or transport line. Each track type is designed to work together so builders can mix gentle scenic sections with fast drops, controlled climbs, or technical coaster elements.

Because the mod uses true spline curves, minecart movement is much more dynamic than in vanilla. Carts bank and rotate along the track, which creates a more immersive ride but can also cause motion sickness for some players. The mod includes a simple configuration command to disable camera rotation for anyone who prefers a more stable viewpoint, and third‑person mode is often recommended for long or intense coaster rides.

Splinecart is popular among players who enjoy building theme parks, rail networks, or cinematic world tours. It’s also useful for creators who want smoother minecart paths for adventure maps or custom experiences. The mod runs on Fabric and supports modern Minecraft versions, with performance tuned well enough for servers that want to host large coaster builds or public rail systems.

Overall, Splinecart transforms minecart travel from a blocky, utilitarian system into a smooth, expressive building tool. Whether you’re designing a full‑scale roller coaster or just want your minecart routes to look and feel better, the mod provides the flexibility and polish needed to make rail transport a standout feature in any world.

This version of the mod is currently the same as the java, and i used a online zip to mcaddon to make the mod so any bugs or if the mod doesnt work, let me know. i havent tried this mod yet but i have seen videos of it and it looks good. this is the first official bedroc port of the splinecart mod. make sure to subscrube to subzero32715!

it was origionally made by foundationgames, so thanks for the origional mod! link to the java version https://modrinth.com/mod/splinecart/gallery

sry as the last version (500 downloads) did not work and was a broken version. this one should work.
