<p>This video shows the moment a train narrowly avoids ploughing into two cars at a level crossing - after leaves on the line caused the barriers to lift too soon.</p><p>The footage, filmed from inside the train's cab, shows the two cars driving across the level crossing in the dark as the train approaches at approximately 45mph.</p><p>The train driver slammed on the emergency brake as he saw the cars - but only managed to avoid colliding with the rear end of the second car by less than half a second.</p>
