Deviation from Standards
How to use an alternative to a requirement in a standard
How to get industry's approval or input to use an alternative?
If you cannot comply with a requirement in a Railway Group Standard (RGS) or a Rail Industry Standard (RIS), you may need industry's approval/permission to use an alternative (for an RGS) or may wish to seek observations on your alternative (for a RIS) from a standards committee. In either case, please complete a deviation application form and submit the application to firstname.lastname@example.org.
Please make sure you also follow any relevant internal process that your company may have for managing and submitting applications before submitting it to us at RSSB.
Your application must be supported by the individual who has professional responsibility for the subject area within your organisation.
Before you start your deviation application
When completing a deviation application, you can find advice on how to set out your case in the ‘Guidance on applying for a deviation’. Following this guidance will help you submit a more robust application and understand what information the Standards Committee will expect to see. Should you require assistance with your application, you may contact email@example.com or Joelle.Parkhurst@rssb.co.uk (020 31425570).
The presentation below sets out the deviation application process through to Standards Committee and to the delivery of the final certificate. Please note this video plays without sound.
Where to find useful information on the RSSB website before completing your deviation application
You may find it useful to check whether there are existing deviation certificates addressing the same issue.
The Deviations Register, updated every three months, gives a list of all current deviations against a specific standard. It is available in PDF or Excel format within the resources section below. The deviation certificates themselves are publicly available and will contain pertinent information relevant to that deviation including the list of supporting information. This information can be made available anytime on request, in particular, where the applicant has given prior permission. Instructions on how to access certificates is provided below.
Supporting information linked to a deviation can be requested from RSSB by completing the Request for Help form and submitting it to firstname.lastname@example.org. Please note that RSSB can only action the request in instances where the applicant has given explicit permission on the deviation application form. In the absence of such permission, RSSB will need to check with and seek permission from the applicant organisation on a case by case basis as the nature and extent of requests may vary.
What do I submit to Standards Committees?
The applicant for a deviation is responsible for providing sufficient information to enable the Standards Committee(s) to take an informed decision on your application.
- Application form (available from the resources section below). Applications should be submitted in electronic format to email@example.com. To help you with completing the form, please see a few examples of applications at the bottom of this page
- Results of consultation
- Any additional supporting information (e.g. scheme plans, risk assessment, graphs, pedflows, etc.).
Submit your application to firstname.lastname@example.org.
Please note: If your deviation application contains a large amount of data, please request a ‘Mimecast Large File Send’ invite from either email@example.com or Joelle.Parkhurst@rssb.co.uk. Otherwise, your application may be at risk of bouncing back without our knowledge.
You (or your representative) may be requested to present your case at the meeting.
Consultation with affected parties
You will need to consult all affected parties who are likely to be materially affected by the proposed deviation and present the results of the consultation to the relevant Standards Committees. This should include a summary of any key issues raised during consultation and how these have been addressed or how you intend to address them.
Include how you consulted the affected parties and the period of time they were given to respond, particularly if you have had a nil return on your consultation. This will help demonstrate to the Standards Committee that you have given the affected parties a reasonable opportunity to comment.
This form may help you when collating consultation comments from affected parties. You may include this form with the supporting information you provide with your deviation application. Should you choose to use it, this form should not preclude from presenting any relevant correspondence from affected parties.
Who are the affected parties?
Depending on the nature of the deviation, the affected parties may be:
- Train operators, either passenger of freight
- Network Rail or other infrastructure manager(s)
- Owners of assets (e.g. ROSCOs)
- Maintainers, suppliers or contractors.
To find out who the affected parties could be, you may want to refer to the list of our RSSB members.
If Network Rail needs to be consulted, please contact them via their consultation email address: StandardsVariations@networkrail.co.uk.
Timescale for submitting a deviation application
Deviation applications should be submitted a minimum of 15 working days (three weeks) in advance of the Lead Standards Committee meeting.
You are strongly advised to submit any deviation applications as early as possible before the cut-off date (Lead and Support Standards Committee meeting dates and associated cut-off dates), so that you can respond to requests for further information prior to the meeting. Applications submitted early are particularly important during initial design considerations or optioneering to facilitate the process for both applicants and the Standards Committee taking a decision on the application.
Standards Committee’s decision or observations
Following Standards Committee approval or observations on your alternative provision, we will authorise the deviation and issue the Deviation Certificate. The Certificate will state the scope and duration of the alternative provisions and in the case of observations include the summary of the comments of the Standards Committee.
Sometimes the Standards Committee approves the deviation but with modifications.
Your application may be deferred by the Standards Committee pending further information. In such cases, the Standards Committee’s Chair and RSSB will help you with your application if necessary.
All authorised deviations are recorded in the Deviations Register (available from the resources below).
Please bear in mind that it is your responsibility to notify the industry parties affected by the deviation (and therefore previously consulted) about the decision of the Standards Committee.
Validity of deviation
The holder of the certificate is responsible for checking that the original assumptions and conclusions contained in the deviation certificate remain valid whenever any material changes occur.
If the conditions of the deviation certificate change, the deviation will no longer be valid. In these circumstances, the holder of the deviation certificate may consider applying for a new deviation.
Please inform the Deviation and Proposals team if you no longer require a deviation so that it can be closed.
Individual deviation certificates can be viewed in the Standards Catalogue under the relevant RGS and issue number.
Examples of deviations:
Time-limited deviation applications:
- GIRT7016 Interface between Station Platforms, Track and Trains:17-087-DEV Liverpool South Parkway Station, Platform 4 extension, isolated columns on platforms
- GERT8000-HB12 Duties of the engineering supervisor (ES): 19-004-DEV New form of High Output Protection Zone - Trials initially planned for Anglia, Wales and Western routes with scope to involve other routes.
Non-time-limited deviations(valid for the lifetime of the asset)
- GERT8075 AWS and TPWS Interface Requirements:17-047-DEV Class 345 Interruption of Overspeed and SPAD Speech Messages on First Cycle.
RIS deviation applications (RIS applications are to gain guidance only)
- RIS-7016-INS Interface between Station Platforms, Track, Trains and Buffer Stops - 19-069-DEV Liverpool Street Station Platform 16 Crossfalls.
Note: RIS certificates are issued for guidance only and would include the Lead Standards Committee and the appropriate Supporting Standards Committees' observations and comments.
If you are a new organisation (such as new franchise holder, etc) which is now responsible for an asset or method of working which may be subject to an existing deviation, and join RSSB as a new member, you may find it useful to check what Deviation Certificates the former organisation held.
You are advised to assess the robustness and adequacy of the current assets and methods of working (including any existing deviations) to ensure that how you plan to operate is safe and meets your legal obligations. This assessment will either lead you to a decision to change something (potentially requiring a new deviation) or you may decide that no change is necessary.
Application for a deviation would be triggered only if there is a need to do something materially different from the existing deviation that has already been applied by the previous organisation.
If in any doubt, then please do not hesitate to contact us and we can provide further advice relevant to your specific circumstances.
