The Dutch rail network is one of the busiest in the world. Dual Inventive has developed a series of solutions to make maintenance of the railway safer for the track workers. These solutions are also more efficient, so that the tracks can be freed for train traffic sooner.

Working safely on the railways with an intelligent circuit breaker

A section of rail track is secured by breaking the circuit between the two track portions with a circuit breaker, in the same way as a section of track is reported as ‘in use’ by a train. The first version of this circuit breaker had to be installed by a track worker manually, but the latest product in the series can even be installed permanently, so that working with the Dual Inventive products becomes even more efficient.
As a partner of Dual Inventive, Core|Vision designed the Electronics and embedded software, making the circuit breaker ‘intelligent’. The self-signalling circuit breaker can monitor itself and reports any problems to the user via a web interface, which was also developed by Core|Vision. During use, the web interface also offers the possibility of checking where the circuit breaker(s) is/are located and the new permanent version can be switched on and off via a PC or with a PDA in the field. About 75% of contractors on the Dutch railways now work with these circuit breakers fitted with electronic innovations.
Core|Vision B.V. is a design house that focuses on the development and implementation of custom solutions in the field of embedded systems. These systems can consist of custom electronics (chips and/or boards), software, standard products or a mix of these. Core|Vision can provide for the entire development process for the client, from advice to design and production.

TPC Electronics is Core|Vision’s partner for the prototypes and final production. In the prototype phase, TPC Electronics checks that the design is producible using a Design for Manufacturing analysis (DFM). TPC Electronics also checks that the components applied are available and where necessary, can submit alternatives. In the final production, TPC Electronics provides for the entire logistical process. Various tests are conducted in the production process to ensure the quality. The print is programmed and, after a final functional test, the product is delivered to Core|Vision.
