of the Netherlands–South African Railway Company on 21 June 1887 in Amsterdam in the Netherlands, funded by Dutch, German, and Boer investors. The Pretoria - Delagoa Bay line, with a length of 562 kilometres (ca. 350 miles), was opened on 6 November 1894 and is still in use today. The railway company employed about 3000 people. Of these, about 1500 were employed in the construction of the Pretoria - Delagoa Bay Line. It adopted the (Cape Gauge) of the neighbouring Cape Government Railways. On 19 February 1896, a train loaded with dynamite was struck by a shunter while being unloaded. The resulting Braamfontein Explosion was one of the largest artificial non-nuclear explosions in history, resulting in more than 70 deaths and 200 injuries. In 1897, a new station was constructed in Johannesburg. The building was constructed in 1895 in Rotterdam and was used in the Amsterdam Exhibition before being dismantled and shipped to Johannesburg, where it was rebuilt in 1897. Although Johannesburg Park Station has twice been reconstructed, the 1897 building was preserved and moved a short distance to Newtown where it still stands, unused, today. By 1899, the NZASM had constructed 1147 kilometres (ca. 712 miles) of railway. The Randtram Line As a result of the rapid development of the goldfields on the Witwatersrand in the 1880s and the demand for coal by the growing industry, on 20 July 1888 the ZAR government granted a concession to the NZASM to construct a railway line from Johannesburg to Boksburg. The line was opened on 17 March 1890, with the first train being hauled by a 14 Tonner locomotive. It became known as the "Randtram", even though it was actually a railway in every aspect and not singularly dedicated to tram traffic. This was the first working railway line in the Transvaal. The concession was extended the following year to continue the line eastward to Springs, where coal was known to exist, and westward via Roodepoort to Krugersdorp. The entire line was opened to traffic on 10 February 1891. In 1889 and 1890, the NZASM obtained three tramway steam locomotives with an wheel arrangement for use on the Randtram line. Since the railway classified its locomotives according to their weight, these tank locomotives were known as the 10 Tonners. As the Randtram line was expanded to the west and east to become the Reef line between Roodepoort and Springs, the 14
