The Passenger Rail Agency of South Africa (PRASA) is quantifying overpayments on its General Overhaul (GO) contracts as part of efforts to recover losses. In May 2026 a SARS audit surfaced that links former PRASA CEO Lucky Montana to an entity that received more than R30 million from the main contractor behind the notorious Afro 4000 "too-tall" locomotives — trains that could not run on much of the South African network.

The SARS audit trail adds a tax dimension to the long-running PRASA locomotives scandal. The findings are reported; Montana has previously denied wrongdoing, and the matters have not been tested in court.
