Trains Pack

Can someone please make an Texture Pack that turns the furnace minecart into a steam locomotive, that has a custom model (which requires OptiFine) while being having the length to be the same as vanilla minecart, and also have the other minecarts to look like various train cars (with the chest cart being a boxcar, normal cart being a passenger car, hopper cart being a tanker car) which have the same length like the vanilla minecart. Also make the texture pack for 1.20.1 because i want to use the Linkart updated mod with this texture pack and i don't want for the minecart models to clip through other minecart models.
