Catalogue Cards

To punch a blank Catalogue Card with a station's location, right-click the Tube Station with it. The card will be labelled with the station's name, or the inventory's if it has none.

Card Decks store punched cards. Right-click while holding a deck to open it, or right-click a card onto the deck to file it. Right-clicking a deck with an empty hand will take the last card out. Bigger decks hold more cards.

Put the decks in a Tabulator Machine on the same tube network as their stations. Every second, the Tabulator Machine retallies each card's station and updates its label. A card whose station is out of reach keeps its last tally.
