Describe the Suggestion

Real life trains probably don't run on lava. Would be nice if the fuel tank supports other fuel from other mods, such as fuels added by The Factory Must Grow. Or maybe add a configuration that lets the player decide which types of fluids (and items) are applicable as fuel and how efficient they are.

that configuration exists through our data driven api, https://github.com/Layers-of-Railways/Railway/wiki/Registering-a-fluid-as-a-Liquid-Fuel-Type

perhaps some default compat could be provided for all the major tech mods that have their own form of diesel?
