From the FAQ on that page:
What key work is taking place in 2021 and beyond?
- We will be OLE piling until the end of this year.
- Later this year, we will begin installing steel masts (which is a less disruptive activity) and we will let you know when this is scheduled to take place.
- Beyond 2021, there will be further associated works in the coming years including signalling upgrades, bridge reconstructions, level crossing improvements and track renewal.
