About
Optimized MTR is a client-side modpack intended to reduce the resource demands of Minecraft Transit Railway, with the goal of improving performance during subway construction and busy train operations. Its creator reports testing it at around 40 FPS on a low-end computer while building stations about 150 metres long, and above 37 FPS during frequent train departures, describing nearly a 40% improvement over the original setup. The package brings together MTR with additions including Tianjin-Metro, the MTR London Underground Addon, Joban Client Mod, Station Decoration, and, in some versions, Mishang Urban Construction.

No harmful code found in its projects
We checked all 97 projects and the files in the pack itself, without running them.
Why we show this: a modpack installs the files of its mods, and each mod runs on your computer like any program. Our checks look for known signs of harm. They cannot prove that a file is harmless. In the grade: a modpack has no grade of its own, and each mod's result counts in that mod's grade.
How we checked
- Its projects97 projects
- Files in the pack itself119 settings files, 1 resource, shader or data pack, 3 other files, 2 mod jars.
- Author on ModrinthThe disclosure form on Modrinth, where the author declares that the project reads or edits things on your system outside the game. Since 13 Aug 2026, Modrinth's rules require it when this applies.Nothing declared about your system outside the game.

7 mods send something about you
We read the code of 94 of its 96 mods, without running it.
Why we show this: a modpack runs the code of its mods, and a mod can send things about you over the internet, like your player name or your login. Contacting an address to check for updates or download files sends nothing about you. Not in the grade: sending data can be normal for what a mod does.
How we checked
- Go online onlyTheir code contacts a web address, for example to check for updates. We found nothing it sends about you.11 mods
- Send nothingTheir code contacts no web address.76 mods
- Not read yetWe have not read their code yet.2 mods
AI
AI used in 7 of the 96 mods we checked
We found an AI tool in them, or their authors declared AI content.
No sign so far that AI was used to make the pack itself
We looked for AI tools in its texts and found none.
We have not read its files, images and code history yet.
Why we show this: some players and servers avoid projects made with AI, and AI in the game can send what you write to an online service. Not in the grade: using AI does not tell whether a project works well or is kept up to date.
How we checked
- Author on ModrinthThe disclosure form on Modrinth. Since 13 Aug 2026, Modrinth's rules require it when a substantial part of the code is AI output, when an asset is mainly AI output, or when the project or its page relies on generative AI.No AI content declared.
- Code historyThe public code on GitHub: who made each change, credit lines such as "Co-authored-by", and its files.Not read yet
- Description and changelogsThe description, project page and newest changelogs: sentences saying an AI tool was used, and text pasted from an AI chat.Nothing found20 changelogs read
