All information about the works has stopped.
I can only recommend that the
OP▸ has a try with that new fangled thing called 'Google' rather than going on an uninformed rant. Use the search term 'Hayes and Harlington station redevelopment', the first result reveals quite a lot of information.
An update was issued on 16th August and described the work which has been in progress during September and October - it has mostly been ground work (e.g. excavating & installing ducting), hence why the OP hasn't seen the glass box station magically pop up. There's also an option to sign up for email updates and some contact details if you have any questions.
Amazing what one can find if one puts a little effort into a task. It's too easy to get all shouty with capitals on an internet forum
And guess what? There was nothing in the Works descriptions about installing / reinstalling better signage and systems for informing intending passengers which platforms their trains might be arriving at. Nor how to purchase tickets when cards do not work in the machines. Nor when staff might be on duty. Nor when proper undercover waiting areas will be provided. Etc. There is nothing in the Works orders mentioning anything to do with services to actual passengers. CJB
