Back in 2014, the SCMP reported on the "painfully slow process" of installing platform screen doors on what were the KCR East Rail and Ma On Shan line (now the MTR East Rail Line and Tsuen Ma Line). 

They returned to the subject in 2023 (paywall) and RTHK reported in February 2024 that work would be complete by the end of the year.  Being the year 2024, of course.

There's an update on the project here and the target completion date is now "in 2025"

The project team has overcome various challenges by learning from experience during the process, hence some of the works could be completed ahead of schedule. The progress of works is satisfactory so far.

Satisfactory, you say?  Completed ahead of schedule?

It's now April 2025, and the southbound platform at University Station has been started but there's no obvious sign of it being completed (northbound was done some time ago).   At Mong Kok East, the two main platforms are complete but not platform 1 (where southbound trains sometimes terminate in the rush hour if they still do that).

I suppose these two are a bit more difficult because the platforms are curved, but that SCMP report was 11 years and yet it's still not finished [and I haven't been to Lo Wu to check on progress there]

I previously wrote about this in January 2018 and Transit Jam reported on one suicide at Kowloon Tong last year (but work there was completed shortly afterwards) and another case happened in January 2025 at University station (The Standard).

And yes, other cities worldwide have a very long way to go to catch up with Hong Kong on this.
