Rerailment

Rerailment is a simple resource pack that tweaks minecarts and rails with the aim to look a tad nicer, and less like a cheese grater.

In specific, minecarts are now made of wood, with a dark iron trim similar to lanterns and chains, and the palette that rails use has been tweaked to look more like iron and less like stone. Emissive textures for active powered, detector, and activator rails are also included for mods such as Optifine that support them (though are not required to use the pack).

Rerailment should work on any modern (1.13+) Minecraft version, so if you are playing on 1.19 as opposed to 1.19.3 (for example), you can safely ignore the "pack was made for a newer version of Minecraft" warning.

This pack also has support for the following mods:

Botania: Minecart with Mana Pool

Supplementaries: Minecart with Dispenser

For other mods, any minecart that uses the vanilla texture should be changed, though the item depicting said minecart type might not be.
