Considering the original title is just the name of the railway, and I do not think “within budget” is editorializing, I think the commenter is being overly pedantic
I was curious about the forecasting success story here too. The German LOK article is better in this regard: https://www.lok-report.de/news/europa/item/62410-oesterreich...
I opened the article expecting to see news about the budget and how they stayed within it, since that SEEMS like the biggest surprising news in a project like this. How is that overly pedantic?
