....I forgot to mention that the Type 43 locos in the post are American General Electric type C30ACi diesel-electric locos designed and built for "Cape" gauge (4 foot 8.5 inches).
About 200 have been built for South African use, but given the gauge there are good prod\spects for sales into Central Africa where similar gauges are used, and in fact 10 have now been ordered by Caminhos de Ferro de Moçambique (Moçambique Railways).
