Bulawayo - Dett is the southern section of the long main line to Zambia via Victoria Falls. Traffic was fairly heavy with coal from Wankie and Zambian copper providing much of the traffic. The line was still largely steam worked by the larger 15th and 20th class Garratts until the early 1990s.
It wasn't an easy line to photograph, mostly running through inaccessible country far from the nearest tarred road, but a few locations could be reached with some difficulty.
