Design and manage a train network! Each tool costs budget.
Station ($60): Click to place a station (up to 12). Cities generate passengers, factories produce cargo.
Track ($40): Click a station, then another station to connect them. Trains travel along tracks.
Line ($80): Click 3+ stations in sequence to build a line. Trains run automatically and earn revenue from tickets and cargo delivery.
Upgrade ($80): Click near a track to upgrade to high-speed (2x faster, more capacity).
Passengers spawn at cities/towns. Cargo from factories delivered to cities earns $15/unit.
