Sulphide Junction Signalling System was successfully commissioned on 27th February 2011.
The system existing at the start of the project was a 28 year old relay interlocking system comprising of a distributed interlocking architecture performing the core interlocking functions within the Relay Room. The higher aspects and train stop controls are managed locally within the distributed locations.
Remote controlled from Broadmeadow using SCADA 2000 links, the system has an Emergency Local Control Panel installed in the Traffic Room of the Relay Room building.
As part of providing improved access to the EDI Downer workshop (Waratah Trains assembly and testing), a heart transplant of the relay interlocking to Microlok in the relay room was planned, mainly to overcome the restrictions placed by "no more than 2 day possession" rules. The external distributed interlocking was left as is, with minimal modifications to accommodate additions/changes, to keep costs down.
