Birley Lane tram update
Over a fortnight ago, I shared some news about the track issue at Birley Lane - engineers had uncovered what appears to be a historic mine shaft or well beneath the tram tracks.
Since then, we’ve commissioned specialist engineers to carry out further studies and review all the historical records. The evidence suggests the structure dates back to the late 1800s and may have been linked to a former coal mine. Some records also describe it as a well used for farming purposes.
We're now carrying out the next phase of investigations to understand exactly what's happening beneath the track. This includes drilling boreholes and using specialist scanning technology to build a detailed picture of the shaft and the surrounding ground.
The challenge is that because of the age of the structure, there are still a number of unknowns. We do not yet know its full depth or the condition it’s in. We're working closely with the Mining Remediation Authority and other experts to make sure we fully understand the risks and develop a solution that is safe, permanent and robust.
I know loads of people will want to know when Blue route services will return to normal. Based on what we've learned so far, this is shaping up to be a complex engineering challenge that is unlikely to be resolved quickly, in days or even weeks. I want to be upfront about the scale of the challenge now rather than promise a plan I can't guarantee we can stick to.
At the same time, I've asked the team to explore every possible option to reduce disruption while repairs are being planned and carried out.
One option under consideration is whether trams could safely operate past the site using the unaffected track. Before any decision is made, we need to be certain that can work safely and without impacting the work needed for a long-term fix.
I appreciate how frustrating all this is, particularly for those who rely on the Blue route every day. Replacement bus services will continue to operate between Gleadless Townend and Halfway, with Supertram tickets accepted. Following passenger feedback, we're also increasing the number of buses along this line of route to get people moving quickly and to make sure journeys are as comfortable as they can be in the circumstances.
Thank you for all your patience and understanding. I'll keep updating everyone as we learn more, and as we continue to try and restore services as quickly and safely as possible.
