A new "railway neighbour" letter has arrived, regarding work taking place overnight (11pm-midday) on Saturdays 18, 25 September, 2, 8 October and from Friday 29 October (11pm) to Monday 1 November (4am) between platforms 4 and 6.
"As part of this work, we need to build a new chamber between platforms 3 and 4. This is in advance of an under track crossing (UTX) being installed, which is required for signalling cables to pass under the track. We will also be carrying over some overhead line equipment (OLE) work including wire runs."
I have to admit, the quality of information conveyed, and the timeliness (and, on recent performance, the accuracy) has improved markedly since two years ago and the "digging up the car park at 1am" nonsense.
As a side note, the reference for the letter is DOL4 42m 61ch, which is really geeky!
