Deviations

Section 6 of the Railway Group Standards Code sets out, in detail, the procedures to be followed for the management of deviations from Railway Group Standards. A deviation is a permission to comply with a specified alternative to a measure or measures in circumstances where it is not appropriate to change the relevant RGS. Such a deviation may be approved by the relevant Standards Committee if the conditions defined within the Railway Group Standards Code are met. Following Standards Committee approval, a deviation is authorised by RSSB via the issuing of an appropriate deviation certificate.

In accordance with the requirements of the Railway Group Standards Code, all applicants for deviations are required to consult with all those industry parties that could be materially affected by the proposed deviation. Further guidance may be found by following the link below.
