Today’s photoessay contains images I initially shot for a client much earlier in the year; the German tunnel-boring specialists Herrenknecht and MMC-Gamuda for the greater Kuala Lumpur mass transit project. The project itself will bring a unified rail system to Klang Valley over the next five years; in the meantime, it’s utter chaos while everything is being dug up or diverted so overhead pylons can be put up. I was hired to document some of the underground work.
