Realistic Cargo Capacity

Cargo capacity now follows the true physical and mechanical stats of each vehicle: 3D dimensions (length, width, deck area, volume), empty weight, engine power (kW), tractive effort/thrust (kN), and era of introduction are combined to dynamically calculate how much cargo a vehicle can actually carry. In the base game, cargo capacities suffer from strange balancing where a modern semi-truck (40 cargo) carries almost twice as much as a 23-meter freight train wagon (22 cargo), and the largest cargo ship (120 cargo) only equals three trucks. With this mod, physical size, mass, and engine power establish a true transport hierarchy: • Helicopters: ~4 to ~38 cargo • Road Trucks: ~6 to ~50 cargo • Cargo Trams: ~9 to ~150 cargo • Rail Freight Wagons: ~14 to ~72 cargo • Cargo Aircraft: ~13 to ~150 cargo • Cargo Ships: ~18 to ~700+ cargo IMPORTANT NOTE ON INDUSTRY BALANCE: Because late-game trains and ships carry realistic bulk loads, vanilla industries can have their storage emptied quickly by large vessels. The "Realistic" setting is carefully capped (e.g. max tankers around ~650-700 cargo to match a maxed Oil Platform's 800 storage), while the "Extreme" setting (up to 2,200 cargo) is designed for my upcoming companion mod, "Growing Industries" (currently in development), which dynamically scales industry production and storage over time. Features: • 4-Parameter Physics Engine: Reads actual 3D model extents, empty weight (t), engine power (kW), thrust/tractive effort (kN), and bogie speed ratings for both base game and modded vehicles. • Era Progression: Modern vehicles gain a capacity bonus to simulate containerization, higher axle loads, and modern logistics. • Economy of Scale (Two-Thirds Power Law): Purchase prices and running costs scale along a realistic surface-area curve so larger vehicles and ships are more cost-effective per unit of cargo. • Proportional Load Speeds: Load speeds are dynamically boosted so high-capacity ships and trains don't sit at terminals forever. • Never Below Default: Vehicles never shrink below their original vanilla capacity. Compatibility: Perfectly compatible with turb02k's "Realistic Seat Capacity" (which this mod was inspired by -> so check it out!). Safe to add or remove from existing savegames at any time. Disclaimer: Generative AI was used in the making of this mod. Mainly because I am not a Lua developer. Every calculation, every algorithm and every idea in this mod was designed by me. Generative AI mostly translated my Pseudocode (and later python code to test my calculations) into Lua.
