krokots: I thought that building railroad networks with depots and connecting them to ports should work, but it don't in GOG version?

I tested this in introduction and normal difficulty.
1) Build a port anywhere in your starting country
2) Find a resource 2 tiles away and build a railroad there, and a depot
3) You don't get that resource in your trade network.

Am I missing something or GoG version is bugged?

gnarbrag: You need to build a depot on the same tile where you placed the port because ports don't count as rail depots.

krokots: Thats it! Is it in the manual? I "only" read the Industrialism wiki, and, though there is much info about most aspect of gameplay, they completely missed that you have to build a depot on a port. So, you have two depots connected by railroad, only then you get resources through ports.
