My Recycling Machines Mod checks every item prototype for certain properties. Your railloader and unloader have the 'place_result' property which suggests that there is an entity prototype associated and that the locale should be in the entity-name section. As a result, my Recycling Machine gives an ugly error display when i hover over your entities in the Recycling Machines menus.
To put this into context, your mod is one of very, very few examples of where this happens. Across all of Bob's Mods for example, it happens only once, for a single entity, and I'm about to make thew same request to him
