Basically, in terms of safety, the rail industry has largely got its act together since the terrible spate of accidents between 1997 and 2002. Last year, there were a billion passenger journeys without a single death. That does not mean there will never be another train crash, accidents will always be possible when large lumps of metal are travelling at 125mph. However, the risks are very low and the BBC's film does nothing to back up its trailer which said, quite disgracefully: "If you knew what we know, would you travel by train?"
