In response to today's (2 November) statement from the Rail Accident Investigation Branch (RAIB) regarding the Salisbury collision, Martin Frobisher, Network Rail's safety and engineering director, said: 'Sunday's accident was incredibly frightening for everyone involved and our thoughts are with everyone injured or affected in any way.

'Initial findings suggest that low adhesion played a key part in causing the collision. It's an issue that affects railways across the world and is something that we, and our train operator colleagues, work hard to combat so that we can run trains safely and reliably throughout autumn, and why incidents such as the one in Salisbury at the weekend are incredibly rare.

'We will continue to work closely with investigators to understand what happened and what more we can do to help prevent this happening again.'

Rail accident inspectors have said it is too early to release indications of what caused the collision between two trains at Salisbury on Sunday evening. But by now CCTV and data logs from signals and trains are likely to have given them a strong idea of what led the Great Western and South Western Railway services to crash into each other. That might prove to be a fault with the signal; or that a train passed a red light; that the brakes failed; or even that the brakes worked but the wheels slid, in the season when leaves on the line can make the rails treacherous.
