THE Freight Rail division of Transnet, South Africa, reported an 8.6% increase in revenue to Rand 22.6bn ($US 3.2bn) for the financial year which ended on March 31. This is despite relatively modest increases in freight traffic and a series of set-backs during the year. These included a three-week strike in 2010, delayed maintenance, inclement weather, derailments, vandalism, and theft of cables.
