Rail chiefs have launched a hard-hitting campaign warning of the dangers of misusing railway crossings. TV adverts show in graphic detail the tragic consequences when motorists and pedestrians dice with death at level crossings. In one sequence captured on CCTV, a group of youngsters is seen playing chicken with a high-speed train. Hundreds of drivers ignore warning signs and lights or weave round barriers at level crossings, Network Rail said. The rail company said there had been 13 collisions between road vehicles and trains this year and Britain is on course for a four-year high total of level crossing incidents unless motorists stop running the risk. Between January and September this year there were 2,636 recorded incidents of misuse at Britain's level crossings. There were nearly 900 incidents involving a vehicle, with 128 categorised as a "near miss", where a collision with a train and serious injury or even death was narrowly avoided. Pedestrians were involved in more than 200 near misses this year.
