Britain’s railway network is full of hidden secrets—from private tracks and underground tunnels to forbidden military railways and secret train lines that the public can’t access. While most people know about the major passenger railways, there are dozens of secret railway routes that still exist, hidden in the landscape or operating behind closed doors.
But what are these mysterious railways? Who still uses them? And can you visit any of them today? Let’s explore the hidden, private, and secret railways of Britain—tracks that most people don’t even know exist.
