The Cape Town Railway & Dock 0-4-2 of 1860 was a South African steam locomotive from the pre-Union era in the Cape of Good Hope.

In 1860, the Cape Town Railway and Dock Company took delivery of eight 4 ft 8 ¹⁄₂ in (1,435 mm) broad gauge tender locomotives with a 0-4-2 wheel arrangement, the first tender locomotives to work in South Africa. They were acquired for service on the Cape Town-Wellington railway, which was still under construction.

In 1872, these locomotives came onto the roster of the Cape Government Railways, which took over the operation of all railways in the Cape of Good Hope. They remained in service on the Wellington line while it was being converted to dual broad-and-Cape gauges from 1872, and were only retired in 1881 when sufficient Cape gauge locomotives were in service.

The first railway line in the Cape of Good Hope, the Cape Town-Wellington Railway, was built by the Cape Town Railway and Dock Company. After having made representations to the Cape Colonial Government in 1853 and 1855, the Company was granted approval, by Act no. 10 of 29 June 1857, to construct a 57 miles (92 kilometres) long railway between Cape Town and Wellington, via Stellenbosch. The company appointed Messrs. E. & J. Pickering as contractors for the construction of the line.

The Act specified, amongst others, that:

Since progress in locomotive design had already advanced beyond the Cape Government's specifications of 1857, the maximum weight and wheel arrangement specifications were, wisely, ignored by the Cape Town Railway and Dock Company. Even the contractor's small 0-4-0T construction engine was more than double the specified weight, exceeding the limit by 8 long tons (8.1 tonnes).

As in England, it was decided to use 4 ft 8 ¹⁄₂ in (1,435 mm) broad gauge. The first sod was turned on 31 March 1859 by Sir George Grey, Governor of the Cape Colony from 1854 to 1861, but the planned railhead at Wellington was only reached on 4 November 1863, after the contractors, Messrs. E. & J. Pickering, had been dismissed in October 1861 and construction was taken over by the Company itself.
