Tributes have been paid to a man with "the biggest heart" who was killed on rail tracks near Dartford station.

Leon Coulthard died after being hit by a train on the line at Stone Crossing on Monday morning.

A British Transport Police spokesman said the circumstances around the death were not suspicious and a report has been prepared for the coroner.

Friends and family have taken to social media to pay tribute to Mr Coulthard, who was only 31 years old.

One friend, James O'Connell, who had planned to complete a 12-mile Tough Mudder challenge with Mr Coulthard later this month wrote: "I didn't really want to post up here but I think I owe it to my brother from another mother. My soul mate.

"He was the best friend I could have asked for and was always there for me like no one else. We shared the best and worst times imaginable.

"Leon had a massive heart, the biggest heart!" - James O'Connell

"Leon had a massive heart, the biggest heart! And so much love to offer, even in his darkest times he was there offering a wise word to help me with my own minor problems, a credit to himself and all who cared for him. What I would do for a hug from Leon right now.

"He loved to give hugs and was never the first to let go.

"Leon was the toughest person I know, a proper fighter and believe me he did not give up easily.

"I will remember Leon in the ring, Leon on the motorbike and Leon on the Dancefloor. Leon the dreamer with huge ambition and crazy ideas.

"Leon with the massive personality and dodgy dance moves."

Mr Coulthard, from Sidcup, was a keen boxer, known as 'King Leon' while in the ring.

He was a popular man, with hundreds of friends. But Mr O'Connell said, devastatingly, it was not enough.

Speaking to the Messenger today, he said: "Leon was depressed and he had demons he just couldn't fight.

"If Leon had lung cancer or some other physical illness, there would have been more people around him. But because it's something people don't really understand he didn't get the support he needed.

"Mental health is still a taboo, they didn't know what was going on inside Leon's head."

The run, on May 21, will now be completed by Mr O'Connell with his brother and the pair are raising money for mental health charity Mind, in memory of Mr Coulthard.
