Wagon Train

Adds Cargo Wagon Train and Passenger Wagon Train, each with three articulated carts and one front horse team. The original two-cart vehicle remains under its existing resource identity for older purchases. The cargo variant has three cargo bays and 72 internal capacity units, corresponding to 18 displayed cargo at the stock factor of four. The passenger variant has three passenger-only compartments and 48 internal units, corresponding to 12 displayed passengers at that factor. Displayed capacity still needs native confirmation. Both new variants define purchase price at 2.5 times their matching stock single vehicle and maintenance at 1.25 times. Cargo uses Horse Carriage; passenger uses Droshky. These are explicit resource prices, not prices derived from tripled capacity. Difficulty, currency rounding and other economy mods can affect the displayed comparison. One stock team's power is retained; the heavier trains can accelerate and climb more slowly. Requires Transport Fever 3 and its stock vehicle resources; no additional mod dependency. Original assemblies, hitch geometry and derived purchase previews by Brian; referenced stock models, meshes, materials and animations by Urban Games. Stock mesh and texture binaries are not bundled. The mod retains its internal ID for save compatibility. Keep it enabled in saves that use its vehicles. Before removing it or returning to an older revision, replace affected vehicles in a backup copy of the save. Release-preparation status: offline structure, resources and economics are verified. The new three-cart variants still need native checks for articulation, boarding/loading, displayed prices, LOD behavior and save/reload. Offline purchase renders are not gameplay screenshots. Console support is not claimed.
