Longest rail tunnel in the world opens in Switzerland

After nearly 2 decades of construction work, the Gotthard Tunnel, the world’s longest and deepest rail tunnel opened in Switzerland earlier this month.

The tunnel is expected to revolutionise travel between northern and southern Europe by providing a high speed rail link underneath the Swiss Alps, moving freight traffic off the road and onto the rails. It is estimated that more than a million lorry loads of freight will move from road to rail.

Whilst the tunnels have been officially opened scheduled services will not begin until December 2016 when up to 265 freight trains and 65 passenger trains a day are expected to run.

Denmark to build world’s longest immersed tunnel

Denmark has engaged in many challenging infrastructure projects in an effort to improve transport links. Over the years Denmark has built many record breaking bridges and tunnels earning it the reputation of a global centre of structural engineering excellence. And they are about to take on their biggest project yet.

Known as the Fehmarn Belt Fixed Link , an 18km long sub sea tunnel to link the German island of Fehmarn to the Danish island of Lolland has been approved. It is thought the construction of the tunnel will have a huge impact on transport in the region and will replace about 2 million annual ferry journeys. It is also believed it will cut rail journey time between Copenhagen and Denmark by 25%.

The project has been approved in Denmark but is currently awaiting approval from the German government.

Tunnelling feats of engineering

As one marathon amount of tunnelling is just completing another is about to begin.

The 26 miles of crossrail tunnelling, linking rail services from Reading and Heathrow in the West to Shenfield and Abbey wood in the East finished in June after 3 years of constant tunnelling. 8 giant tunnelling machines were used constantly to make the network of new rail tunnels, and whilst there are still stations and platforms to construct it is hoped the civil engineering work will be complete in 2017 with the new rail services starting from 2018.

The new services will allow an extra 24 trains an hour to run during peak services and will increase rail capacity by 10% carrying 72,000 passengers per hour through the new tunnels. 1.5 million more people will be able travel to within 45 minutes of central London.

However, as one feat of tunnelling engineering ends another is about to begin. The Thames Tideway Project preliminary construction works begin in 2016, with the proposed 4 years of tunnelling beginning in 2017.

Going Underground

Will this be the way to solve overcrowding in big cities?

For years there has been concern over the space available for new buildings, whether it’s housing or industrial. Skyscrapers have got taller and taller and the space between buildings has reduced. But still, this isn’t solving the problem of overcrowding and in some countries planning authorities are becoming uncomfortable with the higher structures.

Living like the fictional Wombles, ‘underground’ is increasingly looking as though it could become a reality at some point in the future. We travel underground regularly, even using tunnels to get to other countries, so why not take that next step?

Building is the future for PRV Engineering

Having invested more than £1million into the company last year, PRV Engineering Ltd  reported a record turnover in 2013. Twelve months on from the installation of the company’s new plating facility, managing director Simon Jones is confident that 2014 will see a repeat performance.

With the company focussed on the construction industry, PRV Engineering is seeking to not only maintain its high standards, but to add a number of new contracts to the order book.

Simon said; “We had our best ever year in 2013, turning over around £4.1million. The plan for this year is very much the same. We want to keep developing and providing the ‘One stop shop’ service on which we pride ourselves.

Quality is the Number 1 Prerequisite says PRV Engineering

Quality is the Number 1 Prerequisite says PRV Engineering

Quality is the number 1 prerequisite when you drill down to the roots of success. So says Simon Jones, owner and director of PRV Engineering Ltd, one of the fastest growing success stories in the engineering machining services sector in recent years.

The reason that PRV maintain that quality is the number 1 prerequisite, is that it underpins everything else. It doesn’t matter how quickly you can get the job done. Nor does it matter that the price is the cheapest available. If the product, or the service that you supply as a manufacturing and installation engineering services provider does not meet the specification, or the client’s expectations, the other commercial factors are irrelevant. Who better than PRV to know?

The Challenge of Manufacturing Components that Will Last in Harsh Environments

Manufacturing products for what is considered ‘normal,’ or everyday environments has become so commonplace that it can be all too easy to forget that there needs to be a number of considerations for manufacturing products that will be subjected to ‘harsh’ environments.

The specifications and the approach to manufacturing under these harsh conditions must be different. The components that are used, the metals, and other considerations are very often different when working on products that will be used in these harsher, more challenging environments.
