The product acceptance process gives us the assurance that products accepted for use on or about our infrastructure are:
Only accepted products - except those allowed by NR/L2/RSE/100/05 - shall be used on the rail infrastructure.
Network Rail standard NR/L2/RSE/100/05, Product introduction and change, governs the process for the acceptance of products.
You can view the types of products that typically require approval (PDF). Please note that this list is not exhaustive and advice may be required to determine whether your product requires approval.
Please also refer to the Network Rail standard “NR/L2/RSE/06 - How to decide what needs product acceptance”, for further details on the products that this process applies to.
See Accessing Network Rail standards for contractors and suppliers (PDF) for information on standards.
For further guidance please email us at firstname.lastname@example.org
The catalogue of accepted products is available on the PADSnet website.
PADS (Parts and Drawings System) is owned by SERCO and the data is managed by Network Rail. This includes the creation and revision of PADS numbers.
There are more than 85,000 products accepted for use on our infrastructure.
If you have any queries relating to catalogue numbers or PADSnet, please contact the Catalogue Management team at RCandSCatalogueQueries@networkrail.co.uk
You will need to provide justification by demonstrating monetary, safety and / or performance benefits to Network Rail.
Applications should be submitted when Products or Systems have been fully developed and have reached Technology Readiness Level (TRL) 8. Definitions of the TRL levels are available here.
Acceptance is subject to standard terms and conditions which are available in the sample Certificate of Acceptance (PDF).
