The southside stations were identified as a bottleneck for the increased throughput that CRR adds, so Fairfield to Salisbury are getting extra platforms and raised existing platforms to better support NGR. And I think they rolled in the long overdue accessibility upgrades at the same time. AFAIK that was always the plan from the start, but there was also the late addition of the 3 new stations on the GC that have somehow been tacked on to the CRR project.

That street gets pretty busy during peak with drop-offs and commuters, and there’s access to the shopping centre too (which could/should be easily closed). But yeah I wouldn’t have thought it would be super high priority.
