Testing and commissioning of the safety and signalling system

The Noord-Zuidlijn will connect Amsterdam North to Amsterdam South. Daily, the metro line will transport 121,000 travellers through the centre of Amsterdam. The trip from north to south will be cut in half from 31 to 16 minutes.

The metro offers an alternative to the often overcrowded trams and buses. There is no room for even more trams and buses in the city centre. There is, however, room underground. The Noord-Zuidlijn will ensure Amsterdam is and remains better accessible. Good accessibility is essential for the economic development of Amsterdam.


Alstom awarded Omexom the contract to carry out the installation, testing and commissioning of the safety and signalling system for the Amsterdam metro lines, including the new Noord-Zuidlijn. Omexom is also responsible for the implementation of the route from Amstel to Central. Additionally, the security areas (interlocking) at the van der Madeweg, LCM and Spaklerweg are also included in this contract.

The new control and signalling system for the Noord-Zuidlijn and the existing lines will use a partially new radio control system for communication with the metros. To this end, various aerial units are placed on poles and walls. These provide two-way communication between the vehicle and the roadside equipment.


Meanwhile, a large part of the project has been delivered satisfactorily. This is the section from North to South. The following part from Amstel to Central is already in full preparation. This section will be completed by the end of 2016. The expectation is that the first passengers of the Noord-Zuidlijn will be transported in the fall of 2017.

Challenge in Rotterdam

Future mobility guaranteed

One of the challenges in a big city is to give everything a place within the limited space. Burgemeester Oudlaan in Rotterdam is a good example of how living, working, travelling and leisure are combined. The existing rectifier substation for tramline 7 was due for replacement. In order to create space for a student flat, it was decided to move the station. The perfect spot proved to be under the planned new grandstand for the Excelsior stadium.

What was the need:

RET, the public transport company of the city region of Rotterdam, outsourced the engineering, building and commissioning of the rectifier substation to Omexom. The main aim here was to guarantee the quality and reliability of the energy supply for the tram infrastructure. An interesting challenge for Omexom was the limited space for construction. Not only was space required to work safely during construction, areas also had to remain accessible for maintenance after completion.


The project was quite a challenge for the engineers and builders at Omexom, but they were successful. Mr van Heel, Cluster Systems manager at RET: “Omexom’s flexible attitude and the close cooperation contributed to the final result: a well functioning rectifier substation, which had involved many external parties working in a difficult location.”
