The gauge Cape gauge ZR network was built during British colonial rule as part of the vision of the Cape-Cairo railway but the economic spur was to access the mines of Central Africa. The railway started as part of Rhodesia Railways, the company which ran the railways of Northern Rhodesia and Southern Rhodesia as an integrated operation, which was one of the largest employers and enterprises in both countries. The railway arrived in the future Zambia early in 1905 when the 150 km Livingstone-Kalomo line was built in advance of completion in September of that year of the Victoria Falls Bridge from the then Southern Rhodesia to Livingstone. The first wagons on the line were hauled by oxen, then a single locomotive was conveyed in pieces by cableway across the gorge where the bridge was being built to start up operations to Kalomo in advance of the main line connection.
