Previously referred to as ST43, both certification and recertification training is available. 

ST144ST144 or ST43 signal safeworking training is mandatory training for signalling roles within the ARTC, Sydney Trains and John Holland railway networks.  If your job role includes testing, certification, commissioning, like-for-like change overs, alterations or maintenance of signalling equipment (mechanical or electrical) you must complete ST144 or ST43 signal safeworking accreditation and regular ST144 or ST43 signal safeworking refresher/recertification training.

The course has already received lots of positive feedback, a few extracts are below :

"We would like to congratulate you (Competency Australia) on a very well presented and informative ST 43 Course that myself and one of our Signalling Trainees attended.....Our company will definitely be using Competency Australia for further Staff Signalling Training"

"I really enjoyed the course, I've done many ST43 re-accreds in my 24 years but this was probably the most informative and less robotic course of them all"

"I highly enjoyed the course...Look forward to participating in more hopefully in the future"

"the course was very informative and was easy to understand the subjects with the scenario(s)"


This course provides you with current knowledge of ARTC National Signal Safeworking Standards and procedures. 

ARTC ST144 national signal safeworking (ST43/ST144) accreditation is a 4 day certification course.  2-day ST144 signal safeworking reaccreditation courses are also available through Competency Australia.  You can upgrade directly from your existing ST43 certification with a 2 day ST144 national course - existing competency holders do not need to complete a full national ST144 accreditation course. 

This course has now been updated to cover not just NSW but also all other states as required by ARTC, including VIC, SA and WA.
