How to build a minecart loader
This is a minecart loader built in Java edition 1.21.5.
The minecart loader works in the way that when the minecart goes under a hopper and the powered rail is switched off the minecart will stop and load from the hopper. When the hopper has items in it the comparator will light up. This will then switch off the redstone components that are attached these are the redstone dust, redstone repeater and the redstone torch. This in turn will switch off the powered rail that means that the minecart will stop on its next visit. The minecart will pause on the powered rail until the redstone components come back on. This will happen when the comparator registers that the hopper is empty. For this build the player does not have to anything. The only thing that the player will have to do is load up the hopper.

Hopper - to craft a hopper you must first craft a chest.
Comparator and repeater - you must craft redstone torches first.
In this section we will discuss the materials and the ingredients that we need to make this build. This will give a concise list of the items and the recipe's to make them.
Here we will explain in detail how to build a minecart loader in Minecraft. Please follow the instructions carefully.
First up we need to place down a stone block.
Next place a powered rail up against the stone block.
Now place a repeater down up against the stone block opposite the powered rail. As shown in picture.
Place redstone dust down behind the repeater.
First up lets place down a comparator with the two prongs facing the powered rail.
Place a stone block to the back of the comparator.
Put a hopper on the other end of the comparator (ensure that the hopper is pointing towards the powered rail).
Place a redstone torch to the back of the stone block.
Place some rails that attach to the powered rails and place a minecart with hopper down.
What can go wrong - Minecart stopping to early.
The minecart stops early because you have placed two powered rails together by the hopper. You must have a normal rail next to the powered rail that is under the hopper.
Additional builds -
Transport - you can build a complete transport system.
Sorter - you can add a sorter to the loader so that only items that you wish to send will be sent.
