Supposedly the clocks have been sent away to for repair, according to an email reply from FGW▸ (First Great Western) Customer Relations. Whether this is correct or not I wouldn't like to comment, but it would seem a bit foolish if the new CIS▸ (Customer Information System) displays are to be installed by the end of the year, especially as they were working fairly well before they were taken down.
If they have gone for repair, perhaps they should have done them one at a time??
