Coventry has been named a hotspot for railway offences.
The announcement was made as Olympic silver medal winning boxer Amir Khan launched a campaign warning children about the dangers of railway lines as details of the areas worst-hit by rail crime were revealed.
The Commonwealth lightweight champion was in Leeds to promote Network Rail's summer campaign to keep children off the tracks as the city was named the UK's hotspot for railway offending.
According to Network Rail there were more than 15,000 reported incidents of rail crime reported across Britain in 2007, although the company believes the real figure could be much higher.
Leeds topped the table as the worst place in the country with 225 reported incidents. Coventry was ranked second.
Network Rail also said 2,200 objects were placed on the tracks last year and nearly 3,000 missiles were thrown or fired at trains.
The new figures also showed there were 56 accidental deaths of members of the public on the railways in 2007, bringing the total for last five years to 256.
A quarter of these death involved someone aged eight to 18-years-old.
On top of this there were 806 "near misses" in the last five years, half of which involved children.
Today, Khan launched No Messin' Live! - a series of free two-day events held across Britain during the school holidays when rail crime peaks.
These sessions are aimed at giving young people the chance to try a range of new activities and steer them away from the dangers of playing on the tracks, Network Rail said.
"It's really important that young people realise they can be a winner just by taking part," Khan said.
"No Messin' is a great campaign because it gives kids the chance to try something new for free as well as promoting the rail safety message.
"If you mess about on the railways the best you can hope for is that you won't get injured, arrested or even killed."
Martin Gallagher, who runs No Messin' for Network Rail, said: "Too many young people's lives are lost or ruined because they decided to take a short cut or take risks on the tracks.
"Thousands of kids will get the chance to try something much more fun at No Messin' Live! this summer such as canoeing, rock climbing, street dance, archery, kickboxing, wrestling and motorcycling.
"We hope to grab their interest and, working with local clubs, sustain that interest to develop their skills and keep them off the tracks for good.
"This way we can work to reduce rail crime and ultimately save lives."
Network Rail said many of the incidents recorded were various forms of trespass which ranged from people taking short cuts to more serious incidents of kids playing "chicken" with trains.
A spokeswoman said rail crime is estimated to cost the industry £264 million.
