Changes, as filed:

• Track has learned grammar. Every hex is one piece from a fixed catalog, every hex belongs to one block, and junctions take one train at a time. The block overlay paints whole hexes now; junction pockets stand apart in white.
• Multi lane rail grew up: 1, 2 and 4 lanes, every platform lane a berth, capacity counted per lane, and a signal cuts its whole edge.
• Trains no longer jump lanes without track. Lay a CROSSOVER on a multi lane straight and they will plan their own lane changes across it; without one they hold their lane.
• Branching off a dual now peels from the near lane's anchor, in the rails and under the wheels alike.
• Wide gauges and the crossover unlock when your first town makes Village. The rest of the piece cabinet returns later as Blueprints.
• The survey balloon is in: build a shed beside a platform, provision it, and the wind does the rest. New country waits beyond the coast: plains first, Badlands after.
• Towns now eat by the tile: every roof takes its tier's ration, and warehouses grow to match. New businesses take a proper tender: two to four months from demand to ribbon cutting.
• Signals follow the traffic when placed, chevrons march in the travel direction, and stuck trains admit it in the Gazette.
• A train can join a running line, the camera can ride in the cab, and the Feedback button states exactly which build you are complaining about.

The bank trusts these prove satisfactory.
