Trade without sea / ships

[BonPadre]

Ok, either I'm missing something obvious or it's not possible ?
Ok I have never played yet long enough to get to trains, so maybe that's why, but damn seriously, even before train, trade route on land was a thing.

So me being dumb, train is the answer or seriously lacking obvious feature ?

[Oaks]

I haven't tried a landlocked nation yet, but when you go to set up a new trade route are you at least able to trade with folks on your continent?

[VoiD]

You can do it with nations you share borders with, and your subject states' borders also seem to count, I've puppeted everyone between Brasil and the US and I can trade without any ships.

Not sure if customs unions also count.

[Midas]

look into your politic tabs, many asian nations have closed borders for trade, so they cannot trade with others.

Acustom union only negates a part of the political upkeep fee

Ok so it seems I have overlooked the political aspect of it then.

I was asking because I started one of my very first playthrough with Buganda, and the thing is whenever I tried to "trade" the very first thing to pop up is always "port" which you can't build since there is no place to build it. hence my question.

Will try an other playthrough with a probably more open minded place on land then just to try out.
