That incident was utterly unacceptable—there is no question about that—and I am not surprised that my hon. Friend’s constituents are furious about it. The Secretary of State spoke to Andrew Haines, chief executive of Network Rail, at 7 o’clock on Monday morning, and he made clear his dissatisfaction with the incident and demanded action. Network Rail has started an independent investigation to look at how the work was planned and delivered, and how the resulting disruption was managed. It has already made management changes, and new leadership on the Wessex route will start next week. South Western Railway also has lessons to learn, and it must review its communications with its customers. That part is critical and it failed on Monday. It must do far better.
