On a delightful Friday afternoon, to the east of Pretoria, a splendid double-header of historic steam locomotives roars along the Greenview to Sentrarand mainline, heralding the 'Heidelberg Great Train Race!'
At the helm is Rovos Rail's venerable 130-year-old Class 6 locomotive, No. 439, leading the way, with Class 19D No. 3360 in close pursuit.
