6 Alkmaar, easier to maintain due to fixtures from zone A to zone C

Alkmaar station consists of a side platform, a middle platform with a monumental canopy, a middle platform with a modern canopy and a modern indoor passage. The indoor passage was built over the old canopies in 2012 and was fitted with LED lighting from the start, unfortunately with a lifespan of just 5 years while 10 years is now the standard.

The canopies and open platforms had not yet been fitted with LED lighting. Cable ducts were suspended under the canopies with cables for lighting, audio and CCTV. The cable duct with the fixtures was largely located in zone A (between the dotted line and white platform edge, see photo on the left). In this situation, faults can only be resolved in out-of-service mode. As a result, repairs of broken lamps or flickering fluorescent lamps were often being delayed too long (poor score on the ‘Clean and Whole’ KPIs).

In zone C (above the tactile paving),the Lighting Programme installed new cable ducts with LED fixtures underneath. As a result, the centre of the platform is illuminated more evenly and faults can be remedied during the day without decommissioning.

The new cable ducts were concealed by coating them in the same colour as the canopy. We did not remove the old cable ducts to prevent unnecessary issues with public announcements and cameras.

Tips and conclusions:

– Avoid fixtures in zone A or B.

Remove them to zone C.

– Fixtures located towards the centre make for a more evenly illuminated platform.
