A few days ago I got my copy of this game and I can boast of how our trays look with track tiles and wooden tokens.
You need a total of 4 trays 12mm deep with 25 compartments each. Everything fits beautifully in the box (as below).
And last thing: there is a bug on the brown track tiles marked with Y. There should be three spots for stations, but there are two only. Our repair kit will be ready soon and you can add it to your order for free or buy it together with the first mini expansion for this game.
