great progress at OOC, thank you for this. Massive spans. I keep hearing they are going to also start tunnel through to Euston soon. A question is how many HS2 platforms at Euston ? There must be a beehive of activity to get Euston design updated/upgraded too.
Any further construction at Euston has been put on hold until at least 2025 until private investment can be found to complete the job although why any construction company would take on a project that's been such a disaster is a mystery. The two tunnel boring machines have been buried in an underground chamber at OOC & will remain there until a decision is made as to whether Euston will go ahead. If it does, the station won't open until 2040 at the earliest & will be built with only 6 platforms, almost half of its original scope. If it doesn't, OOC will become the main London "hub" for HS2 which means that passengers travelling between Birmingham & Central London will have a longer journey than they do at present which makes a total mockery of the "high speed" moniker. HS2 really is an environmental disaster of epic proportions & Britain's biggest infrastructure mistake in half a century.
