when the train is full, arrive on the unloader, it does not empty.
and when the train arrives on the charger, nothing happens either, I filled the loader with motorized arms because the miniloader does not work

What kind of items are you loading or unloading? Did you set the mod option to “any” to load items other than ore or other bulk goods?

i want to load and unload iron, but it does not work, i will look at the options

same problem in Angels modpack, but they not load/unload vanilla items

BRLs only load and unload ores and similar bulk goods by design.
If you want to load and unload other things, you need to go to the mod options to turn on the cheat "any" option.

Mine was set to "any" yet rich stone wasn't loaded.

See the first FAQ item. Probably you didn't set the option in the correct location.

@therax, there are "multiple" locations where this option needs to be set?
Are you joking?

This is the same for every Factorio mod.

Options set from the main menu affect new games. To change options for an existing game you must load the game first, then set options from inside the save.

Hm, it works now.
nice.

Is there any way to increase the loading speed? Now I'm loading 10k Rich stone in 8s into one High-speed cargo wagon using 12 buffered (every loader has a chest to feed from) Ultimate loaders.
Those loaders are very UPS intensive, therefore I want to get rid of them.

Your Bulkloader loads 10k Rich stone in roughly 36s, which is too slow.
The "deadlock-beltboxes-loaders_2.4.2" can't load directly into the cargo wagons, i can't tell what's the Issue there because the control.lua states:

local inventories_to_check = {
defines.inventory.chest,
defines.inventory.furnace_source,
defines.inventory.furnace_result,
defines.inventory.cargo_wagon,
defines.inventory.assembling_machine_input,
defines.inventory.assembling_machine_output,
defines.inventory.robot_cargo,

I guess these are the supposed legal entities to put materials into, yet these loaders do not put anything into the standard cargo wagons.

I know it's not your business, any help would be greatly appreciated.
