There are two types of couplings typically available on narrow gauge rail freight stock in South Africa. The more robust of these is what is known as the Natal coupling, which is shown in the attached photograph. A decision has been made to retrofit Natal couplings to all passenger and freight stock on the Sandstone Narrow Gauge Railway.

This project will be completed in 2-3 weeks. Because of the larger trains that are being pulled, particularly with triple headers, it is important that the integrity of the couplings be of the highest order.
