Adds massive cargo ships to the game, that function similarly to trains. Also adds tanker ships, train bridges. NOTE: In 2.1, You Must Install Oil Rigs Separately!
This is because the invisible rail from your mod only has the object_layer, but my rail does not and cannot have. Afaik the issue could be fixed if you simply add the rail layer.

I was able to get it to work by adding the rail layer.
collision_mask = {layers = {object = true, rail = true}},
I like both mods and would appreciate if they were compatible
I replaced each {layers = {object = true}} with {layers = {object = true, rail = true}} in water_rails.lua and bridge_gate.lua (%appdata%\Factorio\mods\cargo-ships_1.0.14.zip\cargo-ships\prototypes). It works for me but I can't give any guarantees.
