Doesn't that happen pre-Railroad as well?The problem with all of these ideas is that whatever Civ had the best start position would have a huge advantage with an increased production bonus throughout their empire and tons more gold just because they had a better capital.

Should the Capital get a production bonus when you research railroads? Cities connected to my capital get huge bonuses to their production but my capital doesn't.
A city will also get the production railroad boost if it is connected to the capital with a harbor (both the city and capital have harbor), and railroad is researched. You can chain this out as well -- any city will get the 50% production bonus if there's a "railroad path" from it to the capital, and any harbor connection over water counts as railroad if the tech is known. IE, you can have an inland capital, connected via railroad to a port city, and if that port has a harbor, any other cities connected to the trade network to it via the harbor get the production bonus.
