The TV ad, developed by creative agency iris London, highlights the danger of level crossing misuse, which is currently the biggest cause of accidents on the UK railway.
It carries the tagline 'it's only a matter of time' and flicks between the momentary decision to take a risk and the fatal outcome of doing so. The commercial is supported by three radio executions.
This is the third year that iris London have worked on Network Rail's 'don't run the risk' campaign. Its 2007 campaign targeted 18 to 24 year olds and over 65 year olds, which are the two groups most at risk.
