Home / AEGIS attains Plant Assessment Body accreditation

AEGIS has attained Plant Assessment Body accreditation, adding to its existing Assessment Body status.

AEGIS is pleased to announce that it has been accredited by United Kingdom Accreditation Service (UKAS) for RIS-1710-PLT Plant Assessment Body, this adding to the existing accreditation as a Common Safety Methods (CSM) Assessment Body. In addition, AEGIS is a member of the Network Rail Product Acceptance pilot scheme.


Plant Assessment Body (PAB)

Following an audit by UKAS, AEGIS is very happy to confirm that it has been granted accreditation to undertake assessments in accordance with RIS-1710-PLT for Engineering Certification of Railborne Plant.


This is a new area of business for AEGIS and is a natural progression from the engineering projects it has been undertaking for various clients on on-track machines (OTM) and on-track plant (OTP).


The AEGIS PAB team will be led by Kathryn Ellaby. Kathryn has over 16 years of experience working within the rail industry and has worked for a myriad of companies, ranging from Principal Contractors to Plant hire companies and more recently an Approvals body.  For the past 10 years, Kathryn’s main areas of focus have been; OTP engineering compliance & maintenance, defect trend analysis, plant reliability and procurement.  Kathryn has spent the last 3 years leading and working together with a well-established OTP & OTM approvals team, completing verification reviews against a set of mandated and voluntary standards for various operating companies and Infrastructure Managers.


“AEGIS offers a wide range of engineering services and the addition of the PAB accreditation will increase the company’s ability to provide to the industry.  This is going to be an exciting venture and I am really looking forward to working collaboratively with new and familiar faces”.


Kathryn will be supported in the PAB team by Sam Barrett and Alastair Roberts. Sam is a chartered mechanical engineer whose primary experience is On-Track Plant. Sam’s knowledge extends to the specification and tendering of new plant, incident and failure investigation, risk assessment, conformance assessment and certification and Network Rail Product Acceptance. He also has experience of On Track Machines and Portable and Transportable Plant.


Alastair is a Chartered engineer, a Fellow of the IMechE and PWI with over 20 years railway experience.  He started his railway career working in the Research and Development department of a leading OEM supplying brake systems to the rail industry. Alastair then moved to another OEM company supplying friction management products for dealing with the wheel rail interface.  More recently, Alastair has worked for a leading consultancy and approvals body, delivering a wide range of technical support activities, including reviews against the mandated and voluntary standards for OTP used in the UK and abroad.


Alastair comments, “I am extremely excited about what the future holds at Aegis. I am looking forward to combining may aspects of my previous experience and developing and broadening it further, by working on the wide range of engineering projects which Aegis successfully deliver”.


Additional plant expertise will be provided by Jim Allenden who recently joined AEGIS. Jim is a Chartered Mechanical Engineer and Fellow of the IMechE. He started his career as a Heavy axle and suspension design Engineer with GKN before moving to expand that knowledge to transmissions and whole vehicle design at JCB.  On joining Network Rail in 2008 as Head of Plant, Jim held various technical and business leadership positions culminating in being appointed Engineering Director.


“After an enforced career break due to ill health I am very excited to have joined Aegis Engineering Systems where I can use my skills and Experiences to the benefit of our clients.”


In addition to the certification services, AEGIS can also assist with specialist consultancy services for all areas of OTM/OTP, including generation of compliance evidence and technical files, producing standards checklists, authoring maintenance and operations handbooks and undertaking performance level analysis.


Product Acceptance

As a member of the Network Rail Product Acceptance pilot scheme AEGIS is able to offer Product Acceptance reviews  of all types of plant including OTP, OTM, portable and transportable plant, and mobile plant.
