British rapper Wretch 32 is fronting a campaign warning youngsters of the danger of trespassing on train tracks. The musician insists he is shocked by the number of people who are killed in the U.K. while walking along railway lines, and he is backing a public awareness campaign. The Don't Go hitmaker tells the BBC, "I did skip across tracks and didn't think it was dangerous. You'd just assume you'd make it in time... If you look at the statistics and understand how many people are being hit by trains, it's ridiculous." More than 40 people were killed on railway lines across Britain last year (12).
