what is factorio-blueprints fr?

This project is a set of blueprints for the video game Factorio, a game about building automated factories. In Factorio, players can share prebuilt designs called blueprints so others can copy entire structures into their own game instead of building from scratch. This particular collection is a complete train delivery system, built up over roughly two years, and inspired by a well known community mod called LTN, though this version needs no mods at all to work. The system works on a pull basis, meaning trains are sent out to pick up items only when something actually needs them, rather than constantly shuttling goods around. It includes a central depot where trains refuel and wait, ready made sections of track that line up on a grid so they connect easily, and support for both the game's normal quality items and its rarer legendary quality items. Station settings can be adjusted, such as how many trains are allowed to wait at a station and which stations get priority for deliveries. Regular solid item trains and liquid trains are handled by separate types of stations, and there is a special station type for items that spoil over time. There are some things the system does not handle. It cannot manage trains or stations that carry more than one type of item at a time, and there is no built in way to upgrade a depot from normal to legendary quality. The author also notes a couple of known quirks, such as legendary stations working best when paired with legendary trains, and a rare edge case with spoilable item stations that can occasionally cause loading to pause. To use it, a player needs to place a fueled depot, a fueled train, a provider station stocked with items, and a requester station that needs those items, all connected by track, using the included blueprint set as a starting point. Provider and requester stations each have a small number of settings to fill in, like which item to move, how many trains to allow, and delivery priority.
