I find the reasons for the delay interesting. The "root cause" is arguably not signalling or station fit out, it's the fact that the senior management essentially didn't understand the processes or how progress was being made or not made. Under the original CEO it was going to be delivered in 2018 right up until mid 2018 when they were like "oh sorry, maybe early 2019?". This was a CEO with basically no construction experience who rarely set foot on site. They replaced the CEO a few years ago with someone who has a long career in construction, who understood what it takes to build a railway, who really knows the details, and who is on site, in the weeds, understanding the progress at a very granular level. Since he's taken over the communication has been much better, much more consistent, and felt much more honest. He wouldn't commit to a date, but has progressively shortened the window again and again as they've got closer to completion, and maybe this is naive, but I fully believe that they'll hit the goal of "first half of 2022".
