Splinecart
Splinecart lets players build curved minecart roller coasters from a new rail block that places track ties on any face of another block.
What it does
Track Ties are placed on a face of an existing block, and a second tie is set in a matching orientation further along. A vanilla rail carries a minecart into the first tie, and the track then runs between the two ties. The mod was first made for the ModFest: Carnival event and is meant for smooth, curved railways rather than straight runs of rail.
Two track types are included. Track is a regular rail that minecarts can ride along, while Chain Drive Track always carries minecarts forward and can move them up steep inclines. Splinecart is a Fabric mod for 1.21 – 1.21.3, with the latest file, 0.3.1+1.21.3, built for 1.21.3 and released on 2025-03-26. It is licensed under the MIT License and is open source, and Fabric API is required.
The server and every player need the mod installed. The mod has been available since 2024-06-24 and was last updated on 2025-03-26. Its source code and issue tracker are public.
