What Happened to the Workers Who Built London’s Underground?

The London Underground is a marvel of engineering and a critical part of the city’s infrastructure. However, the story of its construction is often overshadowed by the technological advancements it represents. For over a century and a half, the lauded system was built by a workforce that faced remarkable challenges and sacrifices. This article delves into the lives of those who dug the London Underground, highlighting the methods they used and the fates that awaited them.

Introduction to the London Underground

The London Underground, also known as the Underground, the Tube, or the Underground Railway, is the oldest and second-largest metro system in the world. It was officially opened on January 10, 1863, marking an unprecedented leap in urban transit technology. For almost 160 years, the system has evolved, but the initial construction remains a historic and often tragic tale.

The Early Days: Methods and Techniques

The first phase of the London Underground was built between 1859 and 1864. It was a ambitious project that required innovative construction techniques to overcome the typically poor quality of London’s subsoil. The project was overseen by Sir John Fowler, a distinguished engineer, who was responsible for the overall design and construction.

The tunnelling methods of the time were predominantly cut-and-cover and mining. Cut-and-cover entailed digging trenches, laying the track, and then covering them with earth. Mining involved building a temporary structure, digging below it, and then removing the structure once the tunnel was complete.

The earliest tunnelling techniques were rudimentary, involving the use of basic tools like picks, shovels, and rails. These methods were supplemented by a variety of permanent and temporary underground vaults that allowed workers to build at the bottom of the trench and then cover it with soil.

Technological Advancements: Tunnelling Shields

The development of tunnelling shields was a pivotal moment in the construction of the London Underground. In 1826, Marc Isambard Brunel invented the first rectangular tunnelling shield, which used a series of temporary supports to shield workers from the surrounding earth. In 1865, Peter Barlow designed a circumferential shield, which was later refined by James Henry Greathead for his project to tunnel an 8ft 2.5m diameter tunnel under the Thames.

The tunneling shield developed by Greathead was a revolutionary tool. It allowed for the safe and efficient construction of tunnels, significantly reducing the risk to workers. The shield was capable of simultaneously excavating and supporting the tunnel walls, allowing for continuous and controlled progress without the need for frequent collapses.

The Workers’ Challenges and Fates

Despite the advancements in technique, the construction of the London Underground was notoriously dangerous. Workers faced numerous hazards, including collapses, gas explosions, and the ever-present concern of tunnelling through unlaid bricks beneath buildings. The working conditions were grueling, with long hours and minimal safety measures.

The workers who dug the London Underground came from diverse backgrounds, many drawn from the working classes. They included migrant workers, Irish immigrants, and even some women. These individuals risked their lives to build what would become one of the world’s most iconic transportation systems. As at least one eyewitness recounted: “The digging is hard—very hard. Men die swiftly—and swiftly they forget.

Today, while much of the original tube is still in use, some sections are no longer part of the active network. For instance, the Jubilee Line and two short extensions to the Piccadilly and Northern Lines, which are relatively recent additions, are less than 50 years old. However, the vast majority of the original tunnels were built over a century and a half ago, a period when safety standards and health regulations were far less stringent than today.

Legacy and Modern Perspectives

The legacy of the workers who built the London Underground is one of immense sacrifice and pioneering achievement. By exploring the methods and techniques of their time, we can appreciate the challenges they faced and the ingenuity they demonstrated. The history of the London Underground is not just a story of technological advancement but also a narrative of human perseverance and courage.

Looking ahead, the ongoing efforts to preserve and modernize the system reflect the enduring impact of those early construction efforts. The London Underground continues to be a testament to human ingenuity, a symbol of London’s past, and a foundation for its future.
