Key Aspects of the Zinoco® Coated Rail Installation at South Calton Tunnel
In a significant milestone for the UK rail network, British Steel’s Zinoco® coated rail has been chosen by Network Rail for installation in the South Calton Tunnel, one of two tunnels beneath Calton Hill. The installation, part of a comprehensive £1-million project, aims to enhance the long-term durability and reliability of the tunnel’s tracks. This move is essential to improving both passenger and freight services along the East Coast Main Line.
The Importance of South Calton Tunnel and the East Coast Main Line
The South Calton Tunnel is strategically important as it sits on the East Coast Main Line, a vital railway route that connects major cities including Edinburgh, York, and London. It facilitates crucial passenger and freight traffic, making its upkeep and efficiency essential for regional and national connectivity.
The tunnel runs just east of Edinburgh Waverley Station, making it a key part of the city's transport infrastructure. This area sees heavy rail traffic daily, and any disruption to the line can have a significant ripple effect on the broader transportation network.
Why Zinoco® Coated Rail?
British Steel’s Zinoco® coated rail has been selected for this high-profile project due to its outstanding corrosion protection qualities, particularly in environments such as tunnels and level crossings. Tunnels like South Calton are subject to harsh conditions, including humidity, moisture, and varying temperatures, all of which contribute to the accelerated degradation of traditional rail materials.
Zinoco® is a patented process that provides enhanced protection by coating the rail with a highly durable, corrosion-resistant layer. This coating significantly extends the lifespan of the rail, reduces maintenance costs, and minimizes disruption to services caused by track degradation. The Zinoco® solution was deemed the ideal choice due to its proven reliability in challenging environments.
The Upgrade Process
Network Rail engineers undertook the installation of the new rails during the busy festive period, working tirelessly to ensure minimal disruption to regular services. The project’s timing was crucial as it aligned with a time of year when passenger traffic is typically lower, allowing for faster implementation.
With the installation now complete, the upgraded rails are expected to significantly reduce maintenance needs and improve the overall performance of the tunnel section. The new rails will ensure smoother train operations, reducing the chances of delays and ensuring more reliable transport for both passengers and freight.
Environmental and Economic Benefits
This installation of Zinoco® coated rails will not only enhance the structural integrity of the rail system but also provide long-term economic benefits. Reduced maintenance costs, fewer track replacements, and increased operational efficiency all contribute to cost savings for Network Rail. Moreover, the use of environmentally friendly materials in the rail’s manufacturing process contributes to sustainability goals by reducing the environmental impact of regular maintenance and rail replacements.
