MTR3 Next Technology Addon
by NESTAIDA
MTR3 Next Technology Addon extends Minecraft Transit Railway with script-controlled vehicle speed, speed limits and video frame playback for transit displays.
What it does
The addon adds technical enhancements to Minecraft Transit Railway, letting scripts control how fast a vehicle travels and what speed limits apply along a route. Video handling is built on the JavaCV library, which retrieves MP4 frames and audio data as arrays. Parts of the source were produced with generative AI, the author says.
The mod needs Minecraft Transit Railway, Aphrodite's Nemo's Transit Expansion and Fabric API, and the versions of these dependencies must match exactly. Only the Fabric loader is supported, and the addon is released for 1.19.2 alone. Its files are incompatible with Aphrodite's Nemo's Transit Expansion FIX.
The server and every player need the mod installed. The addon is distributed under a custom license, not an open source one, and public documentation is on the wiki. Version 1.2.8 for 1.19.2 was the latest file, dated 2026-08-28, after the first release on 2026-04-05.
Key features
Script-controlled vehicle speed

Scripts can also define speed limits that vehicles follow along the track.
MP4 frame and audio retrieval
Video frames and audio data from MP4 files are read into arrays through the JavaCV library.
