Traction Enhancement - TGA and ALLEVIATE

ALLEVIATE Rail Traction Enhancer

ALLEVIATE traction enhancers are advanced water-based gels that significantly improve rail traction by enhancing friction between the wheel and rail. These products are specifically formulated to address common rail adhesion issues, providing robust solutions for both seasonal and year-round traction challenges.

ALLEVIATE Key Features

• Viscous Water-Based Gels: ALLEVIATE gels are applied directly to the rail head and do not interfere with track signaling. The gel's viscosity ensures it remains effective on the rail surface, enhancing traction.

• Abrasive Action: By combining abrasive action to break down hardened leaf layers and adhesion enhancing particles for grip, ALLEVIATE effectively increases friction levels, improving rail traction in adverse conditions.

• Cold Environment Suitable: ALLEVIATE LT (Low Temperature) is available with a freezing point of -16°C, suitable for colder climates.

ALLEVIATE Applications

• Seasonal Leaf Fall: In autumn, fallen leaves create a slippery layer on rails, reducing traction. ALLEVIATE addresses this issue by breaking down the leaf layer and restoring traction.

• Wet Rail Phenomenon: Throughout the year, areas of the track can suffer from reduced traction due to moisture. ALLEVIATE is effective in these conditions, ensuring safe and reliable train operations.

• General Low Adhesion Conditions: ALLEVIATE can help improve traction conditions wherever they occur.

ALLEVIATE Benefits

• Improved Braking and Traction: ALLEVIATE restores adhesion levels, reducing risks such as signal failures, station overruns, and insufficient traction on inclines.

• Operational Reliability: By minimizing train delays and operational disruptions, ALLEVIATE helps maintain smooth rail operations.

• Protection Against Wheel Damage: Enhanced traction reduces the likelihood of wheel spin and subsequent damage to both track and vehicle wheels.

Deployment

The deployment of ALLEVIATE can be tailored to meet seasonal needs, such as autumn leaf fall, or used year-round to combat wet rail conditions and other traction challenges. The TGA3 system is designed to apply ALLEVIATE efficiently, ensuring optimal performance and traction enhancement where needed most.

TGA3 Traction Enhancer Distribution System

The TGA3 Traction Enhancer Distribution System, designed by L.B. Foster, ensures optimal application of ALLEVIATE to the wheel / rail interface.

TGA3 Key Features

• Dual Peristaltic Pump/Motor Assemblies: These ensure consistent and even distribution of traction enhancers across both rails, maintaining balanced rail traction.

• 75 Litre Hopper: The substantial capacity allows for fewer refills and extended operational periods, optimizing maintenance schedules and minimizing downtime.

• Remote Performance Monitoring (RPM): Available as an optional feature, RPM provides continuous monitoring via a web-based interface. This feature enhances asset management by allowing operators to monitor performance remotely, ensuring timely maintenance and adjustments.

• Flexible Power Options: The TGA3 can operate on various power sources, including solar, wind, and traditional mains power, offering versatility in different environments and reducing reliance on a single power type.

• Lightweight and Portable Design: With a weight of approximately 45 kg, the TGA3 system is easy to install and maintain, allowing for quick deployment and adjustments as needed.

TGA3 Benefits

• Improved Safety and Reliability: By reducing the risk of station overruns and Signals Passed at Danger (SPAD), the TGA3 enhances safety on the tracks. It also reduces train delays and operational disruptions, contributing to a more reliable railway service.

• Restored Traction on Inclines: The system ensures sufficient rail traction on inclines and other challenging track sections, preventing potential track circuit failures and wheel damage.

• Operational Efficiency: With its innovative design and advanced features, the TGA3 contributes to the overall efficiency of railway operations by ensuring consistent and effective traction enhancement.
