Why this is an optimization mod

MTR 4.0.5 ships 423 vehicle definitions of its own, 378 of which are built-in trains. Every one of them is registered and loaded at startup — models, textures and all — whether or not you ever place a single one.

If your world runs on an addon pack, that is pure dead weight. This mod removes exactly those 378 definitions, so they are never registered, never loaded, and never take up memory or texture space.

Your FPS does not change. What changes is how much the game has to carry around before you have even left the main menu.

What it does

Gone from the vehicle list — no more scrolling past trains you will never place.

Never loaded — models and textures are not registered, so they cost no memory.

Addon packs are safe — any vehicle declared by another resource pack is allowed through by default.

Trains only — MTR’s boats, airships and cable cars are kept.

Pick what to keep, in-game

You do not have to give up all 378. The main menu has a No Original Trains Panel button, which opens a hub with three choices: Built-in Trains, Addon Trains, Cancel.

Built-in Trains

Tick the families you want to keep — families, not individual cars, so keeping SP1900 is one click instead of eight.

Select All / Select None / Reset, plus a collapsible list once it gets long.

A live count of what you have kept, e.g. Keeping 4 / 32 families.

Saving asks whether to restart now or later — the change applies after a restart.

The button anchors itself above the Options/Quit row. If there is not enough room it pushes the vanilla buttons down; if that is still not enough it shrinks itself. It never covers them and never drops below Quit, at any GUI scale — including the Forge layout where Realms and Mods share a single row.

Prefer the config file? Nothing changed: keepIds and extraRemoveIds work exactly as before.

Addon Trains

Lists every pack in your resource pack folder that actually declares vehicles.

Behaviour	Detail
Only real train packs	A pack appears only if it ships an `mtr:mtr_custom_resources.json` containing vehicles. Texture, shader and sound packs never show up, however many you have installed.
Old and new formats	MTR 3 packs (`custom_trains`) and MTR 4 packs (`vehicles[]`) are read the same way.
Three levels deep	Line → model → individual car. The Shanghai pack’s 248 cars open as 18 lines; a line with several models opens into those models.
Tick a line	Blocks every car on that line in one click. Drill down to block a single model.
Real names	Read from the pack file, so a car still shows its name after you have blocked it — no raw IDs.
Nothing blocked by default	Every addon car passes unless you tick it. A built-in train on your keep list stays no matter what you do here.

Search · new in 1.3.0

Every picker screen now has a search box with a Search button next to it. Type, press Search (or Enter), and the list narrows to what matches.

Behaviour	Detail
Searches everything	In the pack list, a search covers all trains of all addon packs at once — not just pack names — and lists the matching models grouped under each pack, with a hit count on the pack row. Click a pack to fine-tune inside it.
Space means AND	`上海 16` finds trains whose name or ID contains both terms. Every term must match somewhere.
Numbers stay whole	Searching `2` will not match `12号线`; searching `16` will not match `16A01`‘s digits inside `AC16`. Whole-number boundaries are respected, so line numbers stop bleeding into model numbers.
Prefixes ignored	`mtr_custom_train_` and `mtr:` are stripped before matching, so you can paste a raw ID from the log and still find the train.
Best matches first	Results are ranked: exact name → starts with → contains → ID only. The train you meant is at the top.
Measured, not guessed	On a 357-car benchmark of two real metro packs, the matcher scores 100% precision and 100% recall — the previous naive `contains` search sat at 90.9% / 95.7%.

Conflict warnings · new in 1.3.0

Some ticks do less than they look, and now the picker tells you before you save:

A “!” mark appears on any car that is also on your built-in keep list — keeping wins, so blocking it there has no effect. Hover to see why.

A pack or model that shares cars with another addon pack gets a conflict count. Blocking a shared car removes it from both packs, and the tooltip says so.

Vanilla-style checkboxes · new in 1.3.0

Checkboxes now draw the same diagonal check Minecraft itself uses — solid when everything under the row is selected, translucent when only part of it is. No more guessing what a half-ticked row means.

Which file do I need

Build	File	Needs
Fabric	`mtr_no_original_trains-fabric-1.3.0.jar`	Minecraft 1.20.1 · Fabric Loader 0.14.21+ · FerriteCore (Fabric) · ModernFix (Fabric)
Forge	`mtr_no_original_trains-forge-1.3.0.jar`	Minecraft 1.20.1 · Forge 47.x · FerriteCore (Forge) · ModernFix (Forge)

⚠️ Both builds share the same mod ID. Install one of them, never both.

Required dependencies

Both builds need Minecraft Transit Railway 4.0.0 or newer, plus FerriteCore and ModernFix as hard requirements. If any of the three is missing, the game stops at the loading screen and names the one that is absent.

Why FerriteCore and ModernFix are hard requirements: MTR addon packs routinely ship very large textures. Combined with decorative mods, the block atlas can grow past the point where Minecraft can build its mipmaps, which causes the game to hang on startup or on world load. These two mods address that directly; without them this mod’s own purpose — running high-quality addon trains on modest hardware — is not achievable.

Works with any MTR 4.x

There is no hard-coded list of trains. At startup the mod reads the train definitions straight out of whatever MTR build you have installed, works out which of them are MTR’s own built-ins, and filters those.

Every MTR 4.0.x and 4.1.x release works, including betas and pre-releases. The only exceptions are 4.0.0-beta-8 through beta-11, which lack an internal method this mod hooks into.

Future MTR 4.x releases work too — when MTR adds, removes or renames built-in trains, this mod follows automatically. No update needed on my side.

If the scan cannot identify MTR’s own definitions for any reason, it falls back to a bundled list rather than risking your addon packs.

It also fixes addon gangways

Some addons — especially ones using the older resource format — end up with missing, black-and-purple, or oddly long connection pieces between carriages. This mod corrects the gangway texture path and makes a gangway render at every coupling point, without modifying your addon zip.

Before you download

Client-side only. Drop it in mods/ and that is it. Servers do not need it.

Multiplayer caveat. Because the filter runs on your client, built-in trains become invisible to you. On a server where other players use MTR’s stock trains, you will not see those trains. The mod is aimed at single-player worlds and servers that use addon trains exclusively.

Upgrading from an older version? Delete the previous jar before installing — the file name includes the loader, and both builds share the same mod ID.

It adds no blocks or items, and never modifies your world or your addon files. Removing the mod at any time restores the default behaviour.

Config (optional). config/mtr_no_original_trains.json is generated on first launch. Everything there can also be set from the in-game picker: enabled, fixGangway, keepIds, extraRemoveIds, blockedAddonIds.

Verify it is running. Search your log for [MTR_NoOriginalTrains]. You should see one line reporting how many built-in trains were removed, and one reporting which resource pack supplied the built-in list.

Not supported. NeoForge on 1.20.1 (MTR has no 1.20.1 NeoForge build), and any Minecraft version other than 1.20.1.
