MTR 4 for Players & Builders

Minecraft Transit Railway 4.0 is a major update to the Minecraft Transit Railway mod, succeeding MTR 3.2. In-place upgrade of existing MTR 3 world are available with minor quirks.

This releases focuses on refining the player experience, fixing numerous long-standing crashes and bugs, substantially improved frame-rate and adding long-requested features such as mixing carriage in a train.

Unlike previous versions where each depot siding can only have 1 train type, MTR 4 allows you to freely fill up a siding with other type of cars.

As an example, you can have an SP1900 (Head), M-Train (Carriage) and K-Train (Rear Head) to create a custom consist for your siding, and let that consist run on the track.

This is useful for mixed vehicle configuration (Such as coupled LRV with different phases), liveries and locomotives pulling other consists.

Train acceleration and deceleration are now separated.

Before placing a track connected to a node, an instant preview of what the track will look like would be displayed when holding the rail item.

Track shape and custom model can now be applied, this feature is incorporated from NTE.

Elevator can now go vertically and horizontally at the same time, horizontal track are now added in addition to the already-existing vertical track.

The rewritten system map nows look better, runs faster and runs more reliably.

Signal lights can now be placed diagonally (In 22.5 deg increments). They can now also be filtered to only show the aspects of certain colored signals.

Train carriage may now sway left and right when the train is running, improving the riding experience.

OBJ model has been incorporated from NTE and is now integrated into MTR 4.

This means MTR can now support detailed train/track models that are exported in the .obj format.

The speed of bridge creator has been increased to a more reasonable speed.

Much of the Distance Effects has been mitigated in MTR 4. Railway facilities and trains will render correctly even in very high distances (i.e. Default world border), and Dashboard will also function correctly with no precision loss when modifying an area.

Rendering optimizations from the NTE Addon has been integrated to the Minecraft-Mappings project, which are also in-use by MTR 4.0. This should offer substantial frame-rate improvements during gameplay.¹⁾

The back-end has been rewritten to no longer run on the Minecraft thread, which means the game loop is able to run faster, resulting in more consistent TPS/Lower MSPT.

The improvements is more visible in large-scale MTR servers with large transit networks.

Major mod compatibility issue reported in MTR 3 is resolved in MTR 4, notable issues including:

• Crash when making a boat depot (MrCrayFish Framework)
• Crash when opening the inventory in 1.20.1 (Botarium)
• Getting kicked out of rocket (Ad Astra)
• Invisible MTR Entity constantly seen when using JEI/The One Probe

Automatic Platform Gates / Platform Screen Doors can now be powered by redstone.

Announcements in the announcer block can now be delayed for a duration of time after the train passes, before playing to the passengers.

Dashboard is now notably smoother than in MTR 3, and also has an underground mode to view surroundings in the player's Y level.

A slab-variants of platform block has been added.

Mosaic Block has been added to MTR 4, which mimics the mosaic tiles seen in various MTR stations.

Due to the new MTR back-end change, currently MTR's train simulation will continue even after the Minecraft game have been paused.

To board the train, you must now board from the door area when the door is opened instead of being in the general train area.

Train movements has been altered slightly in MTR 4 to take account for the bogie position. This may however result in train clipping through very tight tunnels/structures built in MTR 3, and may need adjustments to accommodate for the changes.

Due to the major backend rewrite, most if not all addons depending on the MTR Mod needs to be updated. A non-exhaustive list of addons can be found here, with MTR 3/4 tags appropriately applied to them.

Highly popular addons such as The Tube and Joban Client Mod should already be available for MTR 4, with the exception of Nemo's Transit Expansion, where much of the feature is already incorporated to the MTR Mod.
