On 29 March 2017 the United Kingdom notified the European Council of its intention to withdraw from the European Union (EU). The UK leaves the EU on 31 January 2020 and, as a result of the Withdrawal Agreement gaining the formal approval of both the UK and the EU, we will enter a transition period until 31 December 2020, while the future partnership is negotiated.

The current rules and legislation on rail transport will continue to apply during the transition period and any licenses, certificates or authorisations issued by us and other National Safety Authorities will continue to be recognised in the UK and the EU.

ORR published guidance documents in 2019 to explain the regulations that would have been in place as a result of exiting the EU without a withdrawal agreement (the so-called 'No Deal Scenario'). These documents are now out of date; further guidance will be provided in due course during the transition period.
