Interlocking Solutions in Relay Technology

We have extensive experience in the project planning of interlockings of the Domino-type.

Aside from having extensive experience in new builds and rebuilds of the widely used Domino 69 and Domino 67 interlockings, we also offer our vast knowledge in rebuilds of Domino-C and Domino-55 interlockings. 

We are also highly experienced with the interfaces to electronic interlockings and the project planning of SPS.

We are highly knowledgeable in interlocking and level crossing control systems which gives us the capability to develop new constructions, conversions, and extensions of railway safety installations of any size according to customer requirements.

Our strength lies in implementing the orders in a way that it is economical for the company and costs are optimised. We do not hesitate when it comes to unconventional ways of thinking. Compliance with the rules and regulations is our top priority.

Our expertise and services are directed towards the future. Connections to electronic systems and the associated interfaces are just as familiar to us as SPS- technology for automatic functions in Domino interlockings.
