Rail noise & vibration research project for the RSSB

When the Government tasked the Rail Safety and Standards Board (RSSB) with developing The Sustainable Rail Blueprint (SRB) – they looked to Encompass to provide specialist support with the Quieter Railway piece.

The objective was to help those in the rail industry manage noise and vibration for better health and well-being of all those impacted by rail.

Background

In line with the Government’s commitment to achieving zero carbon by 2050, there is a strong desire to foster more sustainable work practices across all industries – including Rail.

The Government commissioned – The Sustainable Rail Blueprint (SRB) – an industry-wide framework for achieving a sustainable rail industry. The SRB aims to provide a unified plan to make the UK rail industry more sustainable by 2050.

As the independent safety, standards and research body for Great Britain’s rail network, the Government enlisted the RSSB to lead the development of The SRB in conjunction with the whole industry.

Comprising 11 key topics, The SRB covers various aspects, including “A Quieter Railway,” which specifically addresses how the rail industry can effectively manage noise and vibration to improve overall health and well-being.

With the transport industry almost entirely dependent on machines, environmental noise levels have increased, and the population has become increasingly aware of noise as an environmental issue.

The challenge

Like many sectors, the rail industry has developed tactics for managing and measuring noise, with varying degrees of progress. The SRB recognises this and aims for the industry to adopt a standardised approach to noise and vibration – establishing effective strategies and a robust quantitative framework to mitigate its impacts, measure performance and respond to new concerns.

Tasked with delivering the entire SRB, the RSSB enlisted Encompass Engineering for their specialist skills required to support the noise and vibration component of the project.

With their extensive years of experience working on rolling stock projects and their specialist skills in Noise management, Encompass Engineering were well-equipped to help.

Drawing on their extensive knowledge of train design, Encompass brought an in-depth understanding of noise – from the sounds generated by a moving train, including those from wheels, speed fluctuations, rail surfaces and joins, to noise from stationary or slow-moving trains emitting exterior noise through motors, door operations, exhausts, cooling fans, brakes, and heating and ventilation systems. Their expertise also extends to noise emissions from maintenance depots, including factors such as horns, whistles, heavy equipment, and depot movements.

The brief

The RSSB was keen to establish a consistent approach across the industry – establishing benchmarks on noise metrics and how to measure them.

The RSSB tasked Encompass with presenting a noise (and vibration) management strategy for the rail industry and establishing a standardised approach to complaints management by drawing from best practices and lessons learned from rail and other sectors.

The solution

By researching and interviewing key stakeholders and industry specialists, Encompass was able to collate this industry knowledge and combine it with their own extension experience of the rail industry to compile a comprehensive report for the RSSB, which detailed their findings and recommendations for the industry going forward.

Finally, Encompass were able to take these findings and create a template for a best practice noise and vibration strategy and establish a consistent approach to managing noise-related complaints that those in rail could follow and adopt.

The result

With the help of Encompass, the RSSB has completed the noise and vibration section of the SRB. This section outlines best practices, a noise management strategy, and procedures for reporting and monitoring noise and vibration and recommends an effective complaints process relating to noise and vibration in rail.

This research and the subsequent documentation and recommendations are the result of close collaboration with the RSSB, but also Defra and the Department for Transport (DfT).

The DfT has since incorporated noise and vibration management as a regulation into their National Rail Contracts and confirmed that the template and guidance documentation created by Encompass Engineering will be the baseline for these NRC requirements. It is a positive step forward for rail in meeting its sustainability goals.

Case Studies

Strengthening cybersecurity for a new train fleet

Faced with the challenge of balancing strong cyber defenses with operational efficiency, the fleet owner and operator needed expert support.

Encompass Engineering was brought in to assess risks, identify vulnerabilities and develop tailored strategies to strengthen the fleet’s cyber resilience.

Noise management strategy for Northern

In line with new UK DfT requirements - Northern was required to identify and map all noise-prone, densely populated areas and vulnerable locations as part of their noise management strategies.

Northern engaged us to help complete this project. We were tasked with identifying Noise Important Areas, prioritising vulnerable areas and creating a framework for effective monitoring and targeted mitigation.

Maintenance documentation review for West Midlands Railway’s Class 196

West Midlands Railway, a major operator in the UK’s rail network, engaged our team at Encompass to conduct a comprehensive review of their Maintenance Design Justification File (MDJF).

This document plays a key role in ensuring proper fleet maintenance by outlining tasks and schedules essential to the safe and efficient operation of their trains. Our job was to validate this documentation, ensuring that the maintenance schedules matched the actual operational requirements.

Automated Vehicle Inspection System (AVIS) Implementation Support for Rock Rail’s Arterio Fleet

Rock Rail and South Western Railway sought to take a more proactive approach to the maintenance of their Arterio fleet by installing an Automated Vehicle Inspection System (AVIS).

We supported Rock Rail with the system's implementation, ensuring it met technical specifications and delivered reliable, real-time monitoring of train components for early detection of potential issues.

Chiltern Railways – Stourbridge depot noise management project

Chiltern Railways was receiving growing noise complaints from the community around their Stourbridge depot.

They asked us to carry out a noise assessment and develop a Noise Action Plan to address the issue and demonstrate their commitment to resolving the problem and making improvements.

Value stream mapping of rail sidings activities at Tyseley depot

West Midlands Trains has multiple depots across the UK where it carries out essential maintenance tasks. One of their key depots is Tyseley, in Birmingham.

All units arrive and depart in the sidings in the upper part of the depot with direct links to the live network. Between arrival and departure, there are a series of tasks to undertake, which given its state, were challenging to complete and led to depot inefficiencies.
