I would highly recommend this trip to train enthusiasts or anyone who wishes to explore Pretoria.
Friends of the Rail is a non-profit that organises trips to Cullinan on a monthly basis – check out their online schedule for more info at http://www.friendsoftherail.com/joomla/
The trip lasts the whole day and you have 4 hours to explore Cullinan, check out the mine and have some lunch.
Currently, cost is around R250 pp.
Hope you enjoy the vid!
