The strategy for the maintenance and renewal of track on the Great British network has been transformed over recent years. There is now a well embedded pro-active engineering culture of ‘predict and prevent’, rather than a reactive one of ‘find and fix’.

At InnoTrans 2006 in Berlin, Vossloh Cogifer SA, a subsidiary of the Vossloh Group, pre-sented not one, but two innovations in turnout technology primarily for high-speed turnouts. These are, on the one hand, a totally new turnout system for slab tracks, and, on the other, a turnout drive system with…

Currently, all over the world, non-ballasted track concepts are being applied, although still at a moderate volume. If the low maintenance characteristics of slab track on open line are to be retained, great care must be taken to ensure that the subgrade layers are homogenous and capable of bearing the…

Keeping on top of the condition of your track can pay dividends in terms of improved ride and reduced maintenance bills. Modern monitoring equipment allows engineers to plan predictive maintenance. Europe’s railways are stepping up spending on track testing and monitoring. Traditionally, track maintenance has been reactive: in this case,…

The basis for design work for prestressed-concrete sleepers in Europe is EN 13230, valid since October 2002: “Concrete sleepers and bearers.” A supplement to this standard is UIC 713: “Design of Monoblock Concrete Sleepers,” which provides a design example for a prestressed-concrete sleeper. The design bending moment calculated here accounts…

The increasing change in traffic towards rail, the opening of the market in European railway traffic and the increasing responsibility for providers of railways make heavy demands on the quality and the availability of the rail infrastructure. Effective and efficient maintenance concepts are sought after more than ever. New ways,…

The railway infrastructure market needs excellent, sustainable and economical track solutions – these are the words of Klaus Meusel, Member of the Managing Board, voestalpine Bahnsysteme GmbH & Co KG. However this is not merely commentary; voestalpine Schienen GmbH have invested more than €330m in a new rail manufacturing plant.…

The bearing performance of railway embankments on soft ground can be improved by high strength geosynthetic reinforcement products. Under operating conditions, the reinforcement is submitted to static and dynamic forces. The geosynthetic reinforcement products are made out of polymer materials, which show visco-elastic behaviour. Their long term deformation and strength…

Railways are of great social importance. In The Netherlands, a million passengers take the train each day and an increasing amount of freight traffic also goes by rail. Without a safe and reliable network with sufficient capacity, everything would grind to a halt. It is one of the tasks of…

The task of Banverket, the Swedish National Rail Administration, to safeguard the state-owned railway infrastructure is performed with the aid of significant maintenance so as to ensure its operations achieve the transport policy goals set out by Sweden’s Government. Maintenance is a link in securing a transport system for the…

For a company to survive in the hard-fought international railway technology market it must have access to modern, high-performance, reliable and economical machinery. However, high-performance machines are both very complex and expensive to purchase. The technical complexity determines the qualification and training needs of the operating and maintenance staff. The…

When the new high speed line Nüremberg-Ingolstadt is opened for service in 2006, more than 800km of ballastless track will be in operation in Germany. The different systems have undergone extensive laboratory and field tests before implementation on grade, bridges and in tunnels. Available measurement results indicate the expected favourable…
