Crossrail Authorization for Placing into Service – Lessons Learned

Summary

The Central Operating Section of the Elizabeth line is the first large scale railway project in UK to be built and assessed under the Railway Interoperability and Safety Regulations. The Authorisation for Entry into Passenger Service (APIS) by the Office of Rail and Road (ORR) involved the assessment of more than 6000 evidence submissions from 450 projects over different stages of the design, testing and trial operation until completion.

This paper explains how this process was managed and provides learnings which will be of use to future schemes following the APIS authorisation process.
