High Speed Rail Authority
Build America's rail network
Free · In‑App Purchases · Designed for iPad. Not verified for macOS.
Nearly every peer nation runs real high-speed rail. The United States, which built the transcontinental railroad in six years with hand tools, does not.
High Speed Rail Authority puts that job on your desk.
BUILD THE NETWORK
Site your first depot, then draw routes freehand across a real map — genuine coastlines, the Great Lakes, the Mississippi, the Rockies and the Appalachian spine. Terrain is priced honestly: open water costs four times as much to cross, mountain work two and a half, and every major river adds a bridge to the bill. Route around the geography or pay for it.
RUN A RAILROAD, NOT A MODEL
Every rider takes an actual path through your network. Close one line and its traffic reroutes onto your alternates — which can overload them, grinding down track and loading the dice for derailments. Tap any city to see exactly where its riders go, how many transfer, and what a direct line would be worth.
TWELVE REGIONS, ONE COUNTRY
Start anywhere from the Northeast Corridor to Cascadia. Prove the service works and Congress charters the neighboring region — its cities open, and your trains run straight through. Traffic compounds across the whole map.
THREE WORLDS, THREE PROBLEMS
BUILD IT — the United States. There is nothing, and no political will to start.
CONNECT IT — Europe. The trains already exist; the borders between them do not work.
EXTEND IT — Japan. The best network on earth, versus mountains and a shrinking population.
One world is yours free. The others are optional.
SURVIVE THE POLITICS
Award contracts to cut-rate builders or union crews and live with the difference for decades. Set fares by distance or a flat rate. Fund maintenance, or gamble. Appropriations arrive twice a year scaled by public approval, elections swing the legislature for or against you, and every so often a decision lands on your desk: settle the NIMBY lawsuit, or fight it.
FEATURES
• Three worlds — 12 US regions, 11 European, and Japan end to end
• 119 real US cities and 103 European, with real populations
• Free-form route drawing over terrain-costed geography
• Traffic that reroutes, overloads, and breaks
• Three contractors, 13 national programs, change stations
• Elections, appropriations, strikes, and probabilistic disasters
• Three difficulty climates and a guided tutorial
• Autosave per world, a record book, and a National Rail Score
• Built for iPad in any orientation
Ads are optional: watch one by choice for an in-game boost. No banners, and exactly one full-screen ad per game, the first time you expand into a new region. Optional purchases are available and never required. Your progress stays on your device — no accounts, no tracking.
The technology is real. The demand is real. Only the politics is missing.
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
