My earlier posts were written on a break at work. I am at home now in-game and I see where I went wrong. My version of VP is 9-7-2 (finishing a game). In the Civilopedia entry for Railroad, the last sentence reads "Additionally, connecting cities to your capital by Railroad will give them a production bonus."
That tripped an old memory of playing vanilla Civ, connecting by railroad and seeing a boost to city production just from that. It doesn't really matter at this point I suppose, since I think that the game is working as intended, but that is where I went wrong.
Anyway, railroad = faster movement and more production/money, to the tile, if the tile is a city connection. Train Station/Seaport provide the % boost to the city's production after they are built. All good. Thanks again for the answers!
