RDG-GN037 RDG Guidance Note – Issue 1 Date January 2017 Contingency Planning for Power Outages Part 1 About this document 1.1 Responsibilities 1.1.1 Copies of this Guidance Note should be distributed by RDG members to persons within their respective organisations for whom its content is relevant. 1.2 Explanatory note 1.2.1 RDG produces RDG Guidance Notes for the information of its members. RDG is not a regulatory body and compliance with RDG Guidance Notes is not mandatory. 1.2.2 RDG Guidance Notes are intended to reflect good practice. RDG members are recommended to evaluate the guidance against their own arrangements in a structured and systematic way. Some or all parts of the guidance may not be appropriate to their operations. It is recommended that this process of evaluation and any subsequent decision to adopt (or not to adopt) elements of the guidance should be documented. 1.3 Guidance Note status 1.3.1 This document is not intended to create legally binding obligations between railway duty holders and should be binding in honour only.

It is not intended to be an emergency plan in itself, but rather to assist railway undertakings to put in place their own strategic level plans for widespread power outage. 2.2 Scope 2.2.1 This Guidance Note applies to all RDG Train Operator members. 2.2.2 It considers the impact and possible mitigating actions that could be undertaken by a railway undertaking during a widespread power outage, whether planned or unplanned. In terms of scale, it is intended to encompass everything from a localised outage lasting no more than a couple of hours through to a regional power outage extending up to 5 days. 2.2.3 While it does describe more major outages, the circumstances in which they might be experienced and the broad process and timescales for recovering supplies, it does not attempt to explicitly address how railway undertakings should prepare for these, nor suggest that they need to do so. The wholesale loss of the power-generating network nationally is the extreme end of the power outage scenario. All power stations would need to be started from scratch and it is expected that it would take up to 14 days to reinstate the power to its fullest extent. It is obvious that in this kind of scenario, there would be very major consequences for the functioning of the UK as a whole, with the resumption of rail services unlikely to be considered an immediate priority and resources hence directed elsewhere. Running any kind of rail service anywhere on the network in these conditions would be, to all intents and purposes, impossible. 2.2.4 It is therefore upon this middle ground - widespread power failures across large parts of the network, with other parts remaining unaffected - that this document is primarily focused, as it is here that maintenance of a service, potentially involving modified depot, train operations or station working, is possible and hence here that most
