Railways of the World 10th Anniversary Edition Organizer.

thingiverse

This organizer is designed to hold the expansion components that may be used in any game. As a result there's space for the rotors that came from Western US, a special holder for the switch track tiles that came with Australia, a small tray for the tokens from Rail Barons and room in the card tray for the Events Deck, Rail Barons and Transcontinental cards. The card tray works with Arcane Tinmen non-glare sleeves. Other brands of sleeves may or may not fit. I store the components that are specific to an expansion in the expansion box (cards, maps, snow tiles, extra New City tiles, etc.). For any game, I pull out the base game box and the expansion box I want to play. Space is very tight in the base game box, so the player trays only hold two of the Mine and Switch Track plastic models. The plastic miniatures set comes with four of each, but you can only use two per game, so I saved space by only including storage for two of each. The tile tray holds all the straight/curved tiles in the large well and includes a space for each of the three different crossing tiles. I have one or two extra sheets of track tiles (don't remember which), so my tray is a bit overstuffed. I also have a double set of cubes in the bag, so yours will probably take up less space. I have the extra tiles and cubes to accommodate the Transcontinental game. I didn't make a tray to hold the cube bag because it tightly stuffs in the space above the card tray. Without the extra cubes you may need to improvise a bit. The first player box is large enough to hold a bunch of wooden disks in pairs of different colors that I like to use to mark the Major Lines bonus locations on the map. There's enough room to hold the 16 pairs needed for the Transcontinental game.
