Change the Rail "ties" Picture

[TheSAguy]

Hey,

I'd like to update the vanilla rails slightly. Just a tweak to the "ties" graphic.

This is located in the file "..\Factorio\data\base\prototypes\entity\rail-pictures.lua"

What would be the best way to replace
247: { "ties", "__base__/graphics/entity/rails/rail/rail-ties.png" },
341: { "ties", "__base__/graphics/entity/rails/rail/remnants/rail-remnants-ties.png" , allow_forced_downscale = true },

With my images.

{ "ties", "__Bio_Industries_2__/graphics/entities/wood_products/rails/new_rail/rail-ties-concrete.png" },
{ "ties", "__Bio_Industries_2__/graphics/entities/wood_products/rails/new_rail/rail-remnants-ties-concrete.png" , allow_forced_downscale = true },

In the data-updates.lua file?

Thanks.,
