To look at a map of Europe is to see a disconnected landmass. Sometimes described as a ‘peninsula of peninsulas’, the world’s second smallest continent is naturally divided. Even from the centre, it is not always easy to travel to the extremes. Take the Alps for example, since ancient times, they have proven to be...

There are up to 600 disused railway tunnels dotted around the British countryside. Some of these find new life as pedestrian tunnels or storage facilities.

Frustrated with the costs of tunnelling and Hyperloop’s resulting lack of viability, Elon Musk threw down the gauntlet to the tunnelling industry and asked if it could innovate to bring advance rates up to the speed of a snail. In this episode we speak to one of the entrants of the ‘Not a Boring Competition’,...

This week’s episode looks at the long-term expansion plans for the Second Avenue Subway in New York City, as it moves to the final planning phase. The project was first proposed nearly 100 years ago, are the 2020s the decade it is finally going to get off the ground? Photo credit: MTA

For The Tunnelling Podcast’s first “spotlight” episode on waterproofing, we’re looking at the tunnel seals supplied by Trelleborg’s marine and infrastructure operation for the Fehmarnbelt tunnel, the world’s longest immersed tunnel for both vehicles and trains.

A few years ago, two men met to discuss an idea they’d had for a tidal energy project. The idea called for an array of tunnels, rather than the more traditional lagoons. But essentially as the tide comes in and goes out, you can draw the energy off it. It was a fantastic idea, but...

In this week’s tunnelling episode we look at the challenges Texas faces to its water supply and how the recently awarded Section 19 Long Tunnel Crossing, a critical part of the Integrated Pipeline Project, will help bring much-needed water to North Texas.

Singapore’s Land Transport Authority has reached the half-way mark for completing its Circle Line Stage 6, which closes the Circle Line loop by connecting HarbourFront to Marina Bay stations. We take a look at the recently completed tunnelling works for CCL6.

This impressive project completed 50 years ago, and was the most expensive construction job that West Virginia Department of Highways and Virginia Department...

If the Ancient Egyptians had made use of nuclear fuel, their engineers would have needed to find a solution to store the waste not just to today, but far into the future. Fortunately, modern engineers are up to the task. The most advanced project for the disposal of spent nuclear fuel is ‘Onkalo’ in Finland. ...

A career spent in the evolving field of ventilation has yielded a number of insights to Mosen’s Fathi Tarada.  In this episode we tell the story of how the Bahrain oil industry is to thank for a man fighting to bring tunnelling closer to Net Zero, how new ventilation technologies could influence tunnel design, and...
