Mod Splinecart

Splinecart, smooth Minecraft roller coasters

Splinecart is a Fabric mod for Java Edition that transforms minecart travel into a flexible roller coaster building system. It adds spline based rails, allowing builders to create smooth curves, flowing slopes, spirals, and dramatic track layouts instead of rigid vanilla paths. Vanilla rails can connect to custom tracks, making the mod useful for transport lines as well as amusement parks.

Track ties define direction and connect separate points, while regular, chain drive, and magnetic tracks support travel, uphill movement, launches, and braking through redstone. Camera rotation enhances immersion, although players prone to motion sickness can disable it. With BoxToPlay, our team helps bring this creative experience to a multiplayer Minecraft server.
