🛠️ The Track Cleaning Mechanism
The add-on simulates the RHTT’s real-world function, which is critical for maintaining traction and preventing delays during autumn:
- Cleaning Process: The KFA wagons are equipped with high-pressure water jets used to blast leaf debris and oily residue from the surface of the rails.
- In-Game Feature: This function is represented by a visual-only animation in the game, allowing players to engage in the specific operation without changing the track friction model.
🛤️ Gameplay and Configurations
The RHTT operates crucial, time-sensitive services that run outside of the main passenger timetable:
- New Services: The add-on includes 3 new scenarios and 16 additional timetable services that run on the Southeastern Highspeed route (London St Pancras – Ashford Intl & Faversham). These services must be run efficiently between the busy high-speed passenger traffic.
- Wagon Variety: Players can utilize four different specialized wagon configurations, affecting the length and complexity of the train consist:
- Dual Tank with Generator
- Dual Tank with Pump
- Single Tank
- Triple Tank
- Customization: The content is compatible with the Livery Designer, Scenario Planner, and Creators Club, enabling use on other routes via the “Off the Rails” mode.
💰 Route Pricing
To experience the full RHTT timetable and scenarios, the required Southeastern Highspeed route add-on typically costs $39.99 USD, although it is frequently offered at significant discounts.
