Rail map of South Africa, 1892 The map seems fairly accurate, with one exception. The line shown from Grootfontein to Riversdale doesn't exist and never did. Montagu was never reached either. Riversdale was eventually reached by the New Cape Central Railway (NCCR) line from Worcester via Roodewal (Ashton, near Montagu) and Swellendam to Riversdale and on to Mosselbaai.
