John Mitchinson is the most interesting person of Roger Burton. He took us to a defunct London railway to demonstrate the battle between Man and Nature.

I brought you somewhere I think is more than quite interesting. It’s a disused railway line in the north of London. It’s called the Northern Hight’s Railway and it runs from Finsbury Park to Alexandre Palace and then beyond to Edgware. I say it runs, actually, it doesn’t run anymore, it has been completely disused for nearly 60 years.
