Adds massive cargo ships to the game, that function similarly to trains. Also adds deep sea oil, oil platforms, tanker ships, train bridges and other water based content.
Can boats cross those? I was trying to not use those since they feel too cheap. Also it must be a bug that it actually works one way but not the other. I'm definitely not the first who wanted this
Boats can’t cross them, so you use the Cargo Ships bridges over the waterways and the ‘beautiful’ bridges for the rest.
Cost I don’t know about, it would be very straightforward to mod the costs yourself.
In general, when playing with the mod “Cargo Ships” you should expect to transport resources over water using ships, not rail bridges :)
