What Ownit and I did was to meet at a Starbucks at a specific mall, time, date, and told each other, like I'll be wearing a purple scarf. That worked great for us. I think the train station idea would work for you, but maybe a little more specific. Just somewhere public like that but specific enough. (We later realized there's more than one Starbucks in that mall, so it took us a bit longer, but she figured it out!) Good luck! It really is cool to meet IRL.
