300 meters into the
Gautrain tunnel at Marlboro, Sandton.
The Gautrain is a high speed train system that will run between Pretoria, Joburg and O.R Tambo International Airport.
This pic was taken recently on a tour by media to see progress on the project, as most of it is being done underground, the public sees only the sites and dont see the work being done.
The light was horrible and to get decent pics I had to use flash, as can be seen by the reflective stripes on the workers.
