Dallas Delta has provided over 500 Tunnel phones, METS and FETS Graphical control management system and PABX system to run the Emergency Telephones in the M4 tunnels.
The project is about 6.5km long (with 5.5km of the motorway in tunnel).
The M4 East is the first underground section of WestConnex. It will connect to the widened M4 and extend it via twin motorway tunnels from Homebush to Haberfield with three lanes in each direction.

Dallas Delta is currently working on the Emergency Telephone System with SICE an Intelligent Transportation Systems Expert and advanced testing techniques mean that the installation and operations of these phones should run smoothly and efficiently.
