The Mule has travelling up the line to Aylesbury, county town of Buckinghamshire. Although not so many miles away neither of us had visited what is the most sizable stop on the line outside of London. At one time served by the Metropolitan and Great Central railways, Aylesbury is now the end of the line and a pleasant hour’s journey out of London Marylebone on the Chiltern Turbo. The countryside is very much interwar Metro-land suburbia until past Northwood when the urban sprawl turns into countryside and stops become distinct towns in the Hertfordshire and Buckinghamshire countryside. Passing through the modest Chiltern hills we pass the Boer War memorial atop Coombe Hill upon leaving Wendover. Before we realised it we were pulling into Aylesbury.
