A couple who took advantage of their 60-plus travel passes to visit all 32 of the line stations on the London Underground have penned a travel guide based on their adventure.

Author Howard Thomas, 69, has released At the End of the Line, which documents what he and his partner, Kristin Foord, 62, experienced on their travels.

He said: “We have lived in central London for several years and wanted to see what else there was on offer in the far flung outposts of London by taking full advantage of the wonderful freedom passes that we have.”

It took the couple, who live in Islington, more than two years to visit all 32 places, which included Elephant and Castle, Walthamstow, Uxbridge and Ealing Broadway.

Howard and Kristen – who have been together for more than 30 years – hope their light hearted tourist guide will encourage London’s visitors, and even its residents, to explore less obvious destinations off the tourist path.

The couple said that of all of the destinations that they visited – including Woodford and Barking – each stop held something that they enjoyed.

Howard said: “I was pleasantly surprised by Walthamstow. I had never been to the market before and was shocked by how large it was. I also enjoyed visiting the William Morris museum and gardens.

“It was also strange to see how many of the areas did not fit my expectations as places like Chesham, for example, is quite a posh area yet it has lots of charity shops.

“Barking, on the other hand, is a less affluent area but has lots of privately owned shops and was very popular with shoppers.

“We liked Woodford and would go again to spend more time looking around. It was interesting to know that Winston Churchill was the MP for Woodford and this year marks the 50th anniversary of his death.”

Howard, whose career in marketing and sales exports took him to Europe and the Middle East, has long enjoyed train travel and treated Kristen to a trip to Venice on the Orient Express for her 40th birthday.

But one of the most memorable moments from their two-year London expedition was when he was startled by a woman who began to hit him on the Tube.

He said: “It turned out she was trying to save me from a wasp that was crawling up the front of my coat!”

Howard has enjoyed every moment of his time up and down all of the stations and has nothing but praise for the famous Underground.

He said: “People moan when there are strikes but never praise the staff enough when all is running smoothly.

“It has also had a fantastic historical development, just as exciting and groundbreaking as any story.”

The pair finished their journey last year and are now looking forward to their next great adventure.

Howard said: “After we finished, we considered visiting places on the buses instead but some ladies have already covered that.”
