Two tunnelling devices bought to assist develop HS2 have been unveiled by the organization guiding the high-velocity rail line.

HS2 Ltd chief executive Mark Thurston said the machines would “be a defining moment in the record of HS2”.
But campaigners explained HS2 was “decimating countryside and building a enormous monetary burden”.
The two 2,000-tonne machines, crafted at a manufacturing facility in Germany, will dig as deep as 80m (262ft) beneath ground.
They have been named Cecilia and Florence, right after Buckinghamshire-born astronomer Cecilia Payne-Gaposchkin and Florence Nightingale, following a public vote from a shortlist of recommendations built by regional schoolchildren.

HS2 minister Andrew Stephenson said: “HS2 will deliver much better, additional dependable connections that truly stage up our nation, boosting financial advancement and sharing opportunities.”
Florence will be introduced in early 2021, with Cecilia starting the other half of the tunnel about a month later on.
Equally machines are 170m (558ft) lengthy and have been intended for the chalk and flint below the Chilterns.
They will operate nearly non-cease and are envisioned to get about a few several years to excavate the tunnel, which will be lined with concrete.
In Could, a report by MPs found the job was “badly off training course” and accused HS2 Ltd and the Section for Transport of lacking transparency and undermining public confidence.
Campaigners in opposition to HS2 staged a 7 days-long protest along the line’s route in June, declaring money for the venture must be used for the country’s financial recovery following the coronavirus lockdown as an alternative.
