On the 26th of April and the 15th of July edilon)(sedra started the replacement of the block based track system in the tunnel ‘Hemtunnel’ in Zaandam by the state-of-the-art Corkelast® Embedded Block System (EBS), after being almost 35 years in service.
The first 345 blocks from a total of 1.560 blocks were replaced by EBS type 54-E1 in only two short night shifts. edilon)(sedra is responsible for the engineering and production of the blocks as well as the on-site installation, including the delivery of tools and equipment.
Increasingly, EBS is being chosen as the preferred track system for replacing traditional block-based systems in tunnels. The Corkelast® based system offers an easy and flexible installation and therefore a very short out-of-service period. Furthermore EBS is applied because of its durable characteristics. The system ensures a strong reduction of dynamic loads and vibrations and excellent electrical insulation which is important in areas with moisture and/or risk for corrosion.
In the next period the remaining 1.215 blocks will be replaced, after which the Hemtunnel track will ready for many years of safe and reliable rail transport.
