What's New in High Speed Rail Authority

1.1.2

October 31, 2026

THE NETWORK REPORT Operations now keeps a ledger of what every open line costs you per rider it carries, worst first. Each line is flagged with the reason and the fix: winding (with the miles a straightening rebuild drops from every future bill), worn, overloaded, parallel, quiet, or the only link somewhere. Every row has a View button that lands you on that line in Build, one tap from the rebuild and lift buttons the report just recommended. It appears once your network is big enough for waste to hide in. A MAP THAT READS AT EVERY SCALE Zoom out to the whole continent and the map consolidates: major cities plus everything that is yours — your depots, your selection, the route you are drawing — one clean stroke per line, no clutter. Zoom back in and the full detail returns. Large networks stay smooth. THE LATE GAME STOPS LAGGING A continental network used to crawl. The cause was the win-condition check, which cost more than the entire traffic simulation; it is fixed, and the clock runs clean again at every speed. The simulation itself is unchanged — same costs, same riders, same outcomes. ALSO IN THIS RELEASE • Trains visibly run in both directions, which they always did underneath • Drawing a second line between two cities you already connect now says so first, and what to do instead — rebuild it, relieve it, or leave it alone • Charters are purchases now, and each one raises the price of the next: growth is affordable in sequence, ruinous in bulk • Nothing below the map shifts position when partnership offers arrive or expire • Built for iPhone Duo, folded and unfolded
