The rail accident investigators, are very very good engineers. They area ready attend any accident across the UK in a mater of hours. They even have powers of arrest.
Wow great piece of analysis. Quoting: Engineering train crew and contingency at times of peak work will be treated with the same level of nationwide cross-project scrutiny and planning as other resources in short supply, such as signal testers and overhead line engineers.
Also: Contractors will be required to test any new equipment in an off-the-railway environment before it is used on live railway work.
