Post Office rail tunnel turned into high-tech sensor lab (VIDEO)

Installing underground infrastructure in cities could become cheaper and faster thanks to technology being tested in part of the old London Post Office railway.

Cambridge University engineers have turned a section of the capital’s former underground delivery line into a “smart tunnel” laboratory for trialling a range of new sensors that measure disturbances coming from nearby construction works.

The tunnel runs very close to developments for the new Crossrail underground railway and the new technology will enable the researchers to study how existing infrastructure can move and come under strain from other construction.

Being able to better predict what impact a new tunnel would have could make the construction process much more efficient, said PhD student Mehdi Alhaddad, a researcher at the Cambridge Centre for Smart Infrastructure and Construction (CISC). … (Read more)
