Overall project management mandate for the conversion of the switching station and catenary in Spiez

As part of a comprehensive infrastructure project, the 15kV switching station and catenary systems at Spiez railway station were modernised. The aim was to adapt the existing traction power supply to current operational and technical requirements and to ensure long-term security of supply. Enotrac was commissioned by BLS Netz AG to act as overall project manager and coordinate all planning and execution work across all trades involved.

About the project

The 15kV switching station of BLS Netz AG at the Spiez railway junction had reached the end of its service life and needed to be completely renovated. Similarly, the emergency power supply capability of the traction power supply in the event of a switching station failure was not guaranteed and had to be ensured by making various adjustments to the catenary sectioning.

The measures in the switchgear included the construction of new primary technology (switchgear with LTD testing equipment, cable system), secondary technology, catenary protection, electrical self-supply, and various building technology adjustments.

The catenary system and the switching stations were converted to a new power supply concept with decentralised switches, which ensures emergency power supply in the event of a fault and increases operational availability.
