With the Cargo Ships and Rail Types mod, I'm getting the following error:

Error loading mods
Failed to load mods: entity prototype "curved-bare-rail" (curved-rail) collision mask does not collide with entity "bridge_crossing" (straight-rail). rail collision masks must collide with all other rails.
curved-bare-rail modifications: Rail Types
bridge_crossing modifications: Cargo Ships

This is in version 0.17.76

If I remove Rail Types, I still get the Cargo Ships error, so I think this isn't related to your mod.
