In brass, there are only a small number of shipyards available, but it seems in the canal phase this is reduced further. There is a specific rule that says a shipyard cannot be built at the places connected via a rail link, but i don't understand why.
If i have a city card, meaning i can build within that city, what is stopping me build a level 1 shipyard? It has no materials needed to be shipped, so why is this place any different to any other city on the map? Am i missing a specific rule somewhere?
This has been a rule that initially confused out group, until we played online and realised the correct usage (which the rules do backup).
My confusion is that the specific rule says something like
Hence the shipyard in the canal phase cannot be built at this location
And i don't understand the rational.
