Making it into the Guinness Book of Records

In constructing the Doha Metro Rail System, Qatar tunnelled their way into the Guinness Book of Records.

In September 2015, Qatar officially entered into World Records when they achieved the 'largest number of tunnel boring machines (TBMs) operating simultaneously in a single project'. Operating 21 TBMs at the same time, Qatar beat the previous world record of 19 simultaneously operating TBMs.
