| Tatuzão and Megatatuzão side by side |
As of this week the extension to the Line 5 metro line is
being worked on by two giant Tunnel Boring Machines (TBMs) instead of one. This
is the first time ever São Paulo, or Brazil, has ever attempted dual tunnelling
on a single metro line.
The extension, which runs from Campo Belo to Chácara Klabin
station in Vila Mariana and costs R $7.5 billion, will add another 12km of
track and 11 new stations.
However don’t expect it to be open any time soon. The new
TBM humourously known as Tatuzão and it’s partner in crime Megatatuzão will
only dig at a rate 15metres per day. That means the 1.9 km tunnel between LargoTreze, and the first of the new stations, Adolfo Pinheiro, is expected to be
completed only by January next year.
So we can wait a while for the extended Lilac Line 5 to
connect with the Blue Line 1 and Green Line 2 . Still, progress is progress.
