Tunnel, power supply and archaeology updates from HS2

This, from HS2:

We will be advertising on Commonplace three events that will be coming up in late September today, with invites going out to the community. The events will allow people to see the plans SCS have for the tunnel portal at West Ruislip and will give other contractors an opportunity to update on other works such as archaeology and the TBM power supply.

The events will take place on:
Saturday 21 September at Harefield Community Centre 11am to 2pm
Monday 23 September at The Barn Hotel 4pm to 7pm
Wednesday 25 September at Ickenham URC 4pm to 7pm
