Railway Drainage for Platforms, Trackside and Rail Infrastructure
Railways serve as a transport link for many people for work, social events or a transfer betweenairports, cities and towns. On average in the UK, railway stations see up to1.8 billionvisitors per year.
For railinfrastructure,it is essential to have well-designed and efficient surface drainage systems to ensure minimal disruption to rail services, reduce degradation of mechanisms and keep commuters safe.
Depending on the station or time (e.g. peak/off-peak), railway platforms can expect to see anything from light to heavy footfall. Linear drainage must be durable enough to cope with continual foot traffic to ensure longevity. As this is a public area, heelsafe gratings are essential for pedestrian safety.
The safe removal of surface water on railway platforms can help prevent run-off from going onto the track. The material of the drainage system should also be taken into account for platform rail drainage. Composite channels/gratings have non-conductive properties which are recommended to reduce the effects of flux.
Without efficient trackside drainage, storm events can disrupt services caused by surface water flooding. Any engineering work carried out trackside can have an impact on rail operators and commuters.
The speed of installation plays a major role to reduce the amount of inconvenience and getting operations back up and running. Drainage channels that are easy to handle and low in weight provide a quick and simple installation. They offer a cost-effective solution as they don’t needany lifting equipment on-site.
When selecting the right system for your trackside rail project, the HAURATON team will take into account the ground conditions, design, track usage and local climate by using accurate hydraulic calculations.
Over 500 metres of HAURATON drainage channels were successfully laid by Alfred McAlpine Project Services in the cutting approaching of Severn Tunnel East. It was a part of an on-going engineering work commissioned by Western Territory Network Rail that underlines their commitment to provide a safe and reliable railway. Extensive work was carried out on the trackside and cutting slopes on this busy section of line.
RECYFIX STANDARD 300 channels supplied to McAlpine were a good choice as they have a large drainage cross section (863cm²) and yet only weigh 14.4kg per one metre unit. This was greatly appreciated by the contractor as easy manual handling of the channels was essential to reduce hassle on-site and allow faster installation procedures. The work was completed with minimal disruption to services.
The RECYFIX channels were specified to comply with a load category Class C 250 and matched with patented GUGI ductile iron mesh gratings which are secured by eight bolts per metre. The mesh gratings were chosen as it helps prevent the surrounding stone ballast from entering the channel.
As a registered RISQS supplier for the rail sector, our technical sales team and project managers understand the importance of delivering robust drainage systems that provide a reliable performance over many years.

Cable protection for railway infrastructure
Protection of cables for signalling, telecommunications and power is vital to prevent extensive damage. Cable troughs ensure reliable cable management, while still providing easy access for maintenance and servicing operations. Find out more >
Drainage for rail infrastructure: car parks and station forecourts
Aside from tracks and platforms, rail infrastructure covers surrounding areas such as railway station forecourts and parking areas. Typically these areas are impermeable surfaces. Linear drainage systems play a vital role in controlling surface water run-off and the prevention of flooding within these types of locations.
Considerations for drainage at railway station car parks
Station car parks can cover large surface areas. Drainage systems with a large hydraulic capacity will accommodate the flow of vast amounts of surface water.
Station car parks can be subject to pollutants such as microplastics and fuel hydrocarbons. A surface water treatment scheme could be a fundamental part of your project design.
HAURATON have a dedicated rainwater treatment channel that collects, filters and releases purified water back into natural watercourses or sewer networks.
Rail stations can have their very own multi-storey car park. The top deck will require a drainage system to prevent standing water. HAURATON have shallow invert channels for limited to restricted installations.
Whether it is a new station build or refurbishment project, the HAURATON team endeavour to be your end-to-end project support. Get in touch with us to discuss your requirements. For drainage of railway station forecourts, please refer to our public space application.
