Case study

Midland Main Line Upgrade

NCB has been appointed to act as the NoBo (Notified Body), DeBo (Designated Body) and AsBo (Assessment Body) on various schemes of the Midland Main Line Upgrade programme including the electrification from London to Corby, Market Harborough line speed and station improvement, Derby station re-modelling, Kettering to Corby, Kettering station and the GRIP 3 stage of KO1a.

In 2012, plans were announced to extend the electrification of MML from Bedford through to Sheffield, to be completed by 2020. However, the full programme was ‘paused’ in 2015 before recommencing with several key element already complete or underway.

The London to Corby scheme made significant advances by extending the electrification, constructing a new line between Kettering South Junction and Sharnbrook Junction, and introduced a new platform and footbridge extension at Wellingborough station.

Many other enhancements have been carried out to the MML including upgrades to Wellingborough, Kettering  and Market Harborough stations upgraded, line speed improvements and remodelling at Derby station.

How we delivered the project

NCB and our client has established an effective and collaborative working relationship, developing a progressive assurance approach to achieve shared goals. This collaborative approach has enabled the teams to overcome technical challenges together and supported the project in meeting its targets. We have produced key deliverables for significant milestones supporting the projects to achieve successful authorisation of multiple schemes within the MML Upgrade.

NCB is proud to have supported the MML team  in achieving an industry first ‘clean’ authorisation for the London to Corby infrastructure sub-system.

Through actively applying lessons learned and continued improvement from previous schemes we are able to offer the MML Upgrade an approach that is efficient, collaborative and proactively identifies risk to avoid delays and unplanned cost.

One key efficiency is the certification of the new UKMS overhead contact line system on the London to Corby scheme where an intermediate statement of verification (ISV) was produced.  This ISV allows subsequent projects in the MML Upgrade to utilise the certification and avoid cost and save time and effort.
