Factorio city block trains schedule e train limit = 2. Previous system was easier, but it isnt possible in new version. FactorioBin is a site for quickly and easily sharing Factorio blueprints. City blocks are 3 chunks by 3 chunks so definitely smaller blocks, but since its my first train block base I decided to go a bit smaller. Find blueprints for the video game Factorio. Current play through is a semi city block with a main bus. Very large city blocks with a lot of trains can incur a noticeable performance drop since adding a lot of loops in a graph greatly increases pathfinding calculation costs. I'm also obsessed with 1-1 trains and small city blocks. Only thing moving via train is raw resources. If one train fits at the station, and two more trains at the track/stacker before, you set the train limit to 3, to prevent any more trains queuing up that will block the main train tracks.
