Walking with family: Canada to Russia... and beyond

Friday July 3, 2026.

Sunny with a high of 27°C (80.6°F).

As I had the day off work, I had arranged to visit London with my uncle Martin in an attempt to "walk around the world".

I made the short walk to my uncle's house, from where he drove us to Croxley station to catch our Metropolitan line train. Unfortunately, there was a points failure near Wembley Park, so our train would terminate at Harrow-on-the-Hill, from where we would have to board a different train to complete our journey.

We only had to wait for two minutes at Harrow-on-the-Hill station for the next southbound train, which whisked us onwards to Finchley Road, where we boarded a Jubilee line train to complete our journey.

On leaving our destination station, we purchased coffee from the 'Nonna Anna' kiosk, just outside Canada Water station, before beginning our epic trek around the world.

Canada

We entered Deal Porter Square and headed to Canada Water, where we traversed this body of water via the newly installed Rafter Walk boardwalk, which winds along its western edge. In its heyday, Canada Water, then known as Canada Dock, was almost three times the size of what it is now, with much of it being filled in during the regeneration of the area.

We then joined Surrey Quays Road, with Canada Pond and Quebec Pond, now filled in, to our left, before we joined Redriff Road and crossed the border from Canada to Greenland, via the Greenland Dock Bascule Bridge.

Thames Tunnel, Rotherhithe to Wapping

London is a city layered with history, and some of the most fascinating stories lie beneath its surface. One such story belongs to the Thames Tunnel, an engineering marvel that was the first tunnel ever successfully built beneath a navigable river and a project so ambitious it took nearly two decades to complete.

Today, you might speed through it on the London Overground, barely giving a second thought to the brick arches passing by your window. But, in the 19th century, this passageway connecting Rotherhithe and Wapping was the scene of drama, innovation, and, for a short time, one of the city's most popular tourist attractions.

By the early 1800s, London's docks were booming, but the River Thames created a huge bottleneck. Building a new bridge downstream of London Bridge would have blocked the passage of tall-masted sailing ships. The only solution was to go under the river.

Several attempts to tunnel beneath the Thames had failed disastrously. The soft, treacherous ground beneath the riverbed made traditional mining techniques impossible. Enter the brilliant French-born engineer, Marc Isambard Brunel.

Brunel’s genius lay in his invention of the tunnelling shield. The idea, allegedly inspired by watching a shipworm bore through wood, was a revolutionary concept in civil engineering.

Patented in 1818, the shield was essentially a massive, rectangular, cast-iron frame divided into 36 compartments. Miners would work inside these individual cells, digging away a small section of earth in front of them while the surrounding frame held the unstable ground in place. Once a small segment was dug, the shield would be moved forward, and bricklayers would immediately line the new section of the tunnel behind it. This method was the key to conquering the soft, wet subsoil.

Work began in 1825, but the project was far from smooth sailing. It was a harrowing 18-year ordeal, plagued by financial crises, poor air quality, and most terrifyingly, repeated floods as the river burst through the thin crust of ground above.

Brunel Museum

The Brunel Museum is located within the Brunel Engine House building, Rotherhithe. This small but very informative museum allows you to descend into the Rotherhithe Thames Tunnel Shaft and visit the Engine House, where you will learn exactly what went in to building the world's first tunnel beneath a navigational waterway.

Marc Isambard Brunel designed Engine House as part of the Thames Tunnel project. Steam-powered pumps, used to extract water from the tunnel, were originally housed here, although it was used as a boiler house, between 1825-43.

In 1961 the Brunel Engine House opened and offered visitors the chance to see the interior of the building, as well as the Rennie flat V steam engine.

In 1974 the Engine House and Chimney were Grade II Listed. 

Between 1975-79 restoration work to stop structural decay was undertaken and completed.

In 2006 the Brunel Engine House changed its name to the Brunel Museum allowing the museum to incorporate other projects by the Brunel's. A new mural was created on the side of the Tunnel Shaft and benches were created in the style of Brunel bridges, in the garden area.

Refurbishments, in 2007, included the moving of the Rennie flat V steam engine to the Chatham Historic Dockyard, thus creating a larger exhibition space and improved toilet facilities, within the Engine House.

Walking with Keilyn: Brunel Museum to Rotherhithe... and beyond

Keilyn ready to visit the Brunel Museum.

Saturday April 27, 2024.

Another Saturday saw Keilyn and I take another trip to London. Specifically to visit the Brunel Museum, but then to explore the area.

Our trip began the same way as usual; Metropolitan line to Finchley Road and then on to Bermondsey.

Our first stop, on reaching Bermondsey, was to grab a coffee and hot chocolate, which we purchased from the Servewell Cafe, before continuing along Jamaica Road to Southwark Park. The forecast said that rain was due at around 14:00, so we decided to visit Southwark Park before it began.

We visited the bandstand, before passing the bowling green, crossing Carriage Drive, where we discovered the Caryatids of Rotherhithe Old Town Hall.

From here we entered the Ada Salter Garden and then made our way around Southwark Boating Lake, before heading back towards Jamaica Road and King's Stairs Gardens.

From here it was a short walk along Saint Marychurch Street to the Brunel Museum, passing the historic Mayflower pub along the way.

To our surprise the Brunel Museum was deserted, so we had the entire place to ourselves for our entire visit. After purchasing our tickets, Keilyn was issued with a clipboard with two sheets of questions about the museum and the history of the Thames Tunnel, called 'The Brunel Detective Trail'.

Keilyn 50-feet down the Thames Tunnel Shaft.

Our first stop was to the Thames Tunnel shaft, from where the tunnel's construction began. After being ushered in to this cavernous shaft, with its bare brick and smoke-coated walls, we were left to explore on our own. At the bottom of the shaft Keilyn and I took a seat and watched a 4-minute video, that was set on a continuous loop, that explained the reasoning, construction and effect the Thames Tunnel had on London and the world. As we watched the video we could hear, and feel the London Overground (The Windrush line, from Autumn 2024) rumbling past beneath our feet.
