Sydney, NSW, Australia - Arcadis developed a lock out system for Sydney Trains Maintenance Centres to eliminate the risk of electrocuting maintenance staff working on trains.
This included developing the concept and undertaking the detailed design for the railway signalling and safe working systems required to achieve this, which has included the production of safety documentation such as:
The scope of the project required a new lock out system to be developed within a short time frame. Any delays to the project would have meant Sydney Trains would not have been able to maintain their train sets, and consequently these would have progressively come out service, causing major disruptions to timetabled train services across the Network.
The new lock out system ensured the safety of staff (over 50 plus) within the maintenance centre. The system is rated for use in safety applications up to SIL 3 (EN/IEC 62061) and Category 4 PLe, these safety requirements more than exceeded the client’s safety requirements.
Within a 4 month period Arcadis developed the safety requirements for the new lock out system, sourced suitable components and designed and commissioned the new system, the first of its kind on the Sydney Trains rail network.
