The long crafting time is part of my design idea, as every intermediate product is also "crafted" using the specific recipe, which adds extra time. In a mod setting of the base mod, you can damp the crafting time for all intermediate steps, but it will always be at least as slow as the last step (in this case, the rails themself).
So it is a convenience and less of a "very fast crafting shortcut".
I also know that Extraplanetary Production has many many overlaps with my mods (not only this one here), therefore I was not sure if it is used in parallel.
In this specific case, the fact that my mod is overwriting EPs recipe: Sure I could make an exception in one of your suggested ways, but I like generalisations. Are there any other "conflicts" you know of?
Thanks for the report and I am glad you like this mod.
