Railway Profit Tuner (Cities: Skylines 1 Mod)

A lightweight Cities: Skylines mod that reconstructs the cargo train income logic based on distance and cargo size. Built with Harmony Lib.

🚀 Overview

By default, cargo rail maintenance in Cities: Skylines can be a financial burden. This mod adds a realistic revenue stream by calculating a "delivery fee" whenever a cargo train arrives at its destination.

Formula

$$TotalIncome = (BaseFee + (Distance \times 50) + (Cargo \times 20)) \times Multiplier$$

🛠 Features

• Dynamic Calculation: Real-time distance and load-based rewards.
• In-game Settings: Adjust base fee and multiplier via the Options menu.
• Persistent Config: Settings are saved to RailwayProfitConfig.xml in the game's local folder.
• Performance Optimized: Uses Harmony Postfix to ensure zero impact on core simulation logic.
