A minimalistic mod allowing changing vanilla belt settings, including belt speed and underground belt max distance.
Also adds options on unlocking loaders.
Supports mods “Deadlock's Stacking Beltboxes & Compact Loaders” and “Space Exploration”.


Feel the vanilla transport belts being too slow, especially when compared to the logistics bots?
Feel the express transport belts still inferior to logistics bots, regarding its cost?
Want to scale belt speeds to other mods?
Want the underground belts to go further?
Want to use the vanilla loaders, without adding any new entities to save memory usage?
If you have any of these wishes, this mod is for you!

This mod does NOT add any new items or entities to your game, so will not use extra memory or take longer loading time.

This mod allows editing belt settings from the options menu, under "Options" → "Mod settings" → "Startup" tab.


Belt Speed

For current base game version (0.16.51), the basic transport belt has the base speed. (For belt physics, please see this document.)
In short, the base speed of 15 items/s (game version 0.17.4) is used to define the speed scale = 1. The fast and express belts being speed 30 and 45 items/s, have speed scale of 2 and 3 accordingly.

This mod allows you to freely set the speed scales. You can set any numbers you want, even with non-integral numbers. It is advised to use one of the following sets though.

Belt Type Vanilla Speed Scale Suggested Scale I Suggested Scale II
Basic 1 (15 items/s) 1 ( 15 items/s) 1.5 (22.5 items/s)
Fast 2 (30 items/s) 3 ( 45 items/s) 3 (45.0 items/s)
Express 3 (45 items/s) 8 (120 items/s) 6 (90.0 items/s)

Beware that if speed is too high, say scale 16 (213.33 items/s), many things including the belts will glitch and not working in some way. (Tested under 0.16.51, where scale 1 = 13.33 item/s.)
- (Tested on game version 0.18.30) At scale 8 (120 items/s), even fast inserters are not fast enough to grab items from non-full belts. You may want to reserve such high speed for mainbus, using splitters to divert to lower speed belt for production input.
- (Tested on game version 0.18.30) Scale 8 (120 items/s) is the maximum speed for any loaders, due to engine limitation.
- (Tested on game version 0.18.30) Beyond scale 8 (120 items/s), items on belts begin to glitch, not flowing normally all the time.
- (Tested on game version 0.16.51) At scale 12 (160 items/s), splitters is still working fine. They may stop working and blocks if set to be higher. This mod has a soft safety limit at this scale.
- (Tested on game version 0.16.51) At scale 16 (213.33 items/s), even the belts will glitch (non-full belts). If you want to test the "limit" of the game engine, you may edit the settings file with a text editor and test yourself.

Maximum Distance

The underground belts of 3 tiers can go maximum distances of 5, 7 and 9 respectively, in the base game. Two suggested settings are listed below.

Belt Type Vanilla Distance Suggested I Suggested II
Basic 5 8 16
Fast 7 16 32
Express 9 32 64

Unlocking Loaders

A loader is an entity placed between a belt and a container (e.g., chest, assembling machine). It transfers items between them, depending on the direction of placement. Inserters do have similar role, but loaders perform at the speed of the belt.

The base game have three hidden entities: loaders of three belt speeds. They exist in the code, but hidden because of "balance" concerns.
This mod set the speed of loaders to change accordingly, and provide the options to allow them for players' use. The three tiers of loaders are unlocked by the three logistics technologies (just like the belts, underground belts, and splitters). The default is off. You will need to check the "Enable Loaders" option to enable them.
In case you have already installed other mod introducing loaders, you should keep this option off.

If enabled, this mod adds these loaders together with custom graphics, replacing the vanilla B/W arrow plate placeholder graphics. Hotkey (can be adjusted in "Controls") is also added, to allow quick adjustments of loader direction and orientation.
There is another minor feature. This mod modifies the flags, so loaders can be upgraded using the new 0.17 "Upgrade Planner", just like what can be done to belts.


This mod do not modify the existing content in the save game. This mod should be safe to be disabled/uninstalled at any time.

Mods Compatibility

The main purpose of this mod is to allow modifying speed of vanilla belts. So if any mods remove and/or rename the vanilla belts, this mod is not needed anyway...

If any other mods unhide the vanilla loaders, they should take precedence. Therefore, please uncheck "Enable Loaders" option of this mod, under "Options" → "Mod settings" → "Startup" tab, to avoid "double unlocks" on the loaders. Apart from that, these mods should work together.
