please explain how ONRSR contributed to this particular incident ?
in 13 years as a network controller nothing has come from onsr that has made things we do less safe.
Really? Had a look at the ATSB RepCon reports recently?
The reporter has expressed a safety concern regarding the lack of training provided to employees and inadequate promotion of updated operational procedures.
The reporter states that {operator] has released approximately 270 operational document changes to their train crew since 01 January 2018. Each of these requiring the employee to read the document, interpret any changes from the previous edition and recall these in an operational environment. Of these 270 changes, 158 were Operational Procedure changes, 46 Operating Instructions (which by definition alter an existing operational procedure that then needs to be cross-referenced), and 63 Operation Notices.
--SNIP--
ONRSR has reviewed the information contained within REPCON RR201800031.
ONRSR is satisfied that there is sufficient evidence to demonstrate that at the time of this response, [operator] have systems to manage so far as is reasonably practicable, the risks associated with management of change including training and consultation with rail safety workers.
270
operational document changes in less than a year and ONRSR doesn't think there's a problem with people keeping up to date, because the Operator says so. Riiiigggghhhttt.

Here's another:
The reporter advised that changes regarding work on track authorities were made to the NIB on 10 January 2019; however, staff responsible for implementing the changes were only made aware of the amended procedures 12 days later, via an email. Responsible staff were continuing to request work on track authorities that contravened the amended procedures as late as three weeks after the changes to the NIB were initially made.
--SNIP--
ONRSR has reviewed the information supplied by the reporter and the response provided by the operator. ONRSR has made further enquiries with the operator regarding this matter and is satisfied with the operator’s response.
Another operator, another employee with concerns about working to out of date documents, yet ONRSR says "She's apples!"
Here's another you might be able to relate to:
The reporter has raised a safety concern relating to insufficient document control by [the Operator] train controllers.
The reporter states that controllers regularly issue Work on Track Authorities on night shift without the paper train graphs being up to date at the time of issuing the authority.
--SNIP--
ONRSR conducted regulatory activity in February 2019 regarding this matter and as a result, the operator is implementing a safeworking improvement plan. ONRSR will monitor the implementation of this as part of the 2019 National Work Program.
I dunno about you, but to me when you have multiple people, from various operators and various disciplines complaining about similar issues, maybe
there really is an issue and ONRSR should not just say "Oh, they've done this and we're happy with that!".
Because the concern for me is, while I might think I'm doing the right thing, someone else might think differently and
that doesn't work in a safety-critical role...
