Simmer & Jack station name comes from two individuals who in 1887 started mining in the reef area for gold, Their names August Simmer & John Jack. The station was in operation & manned till 1938, when the mining area around the station grew and a deviation of the line was needed. A new deviation and new stations were build for Geldenhuis and Simmer & Jack, and the line was equipped with electric overhead lines and colour light signals. With the new deviation in operation, Simmer & Jack along with Geldenhuis was no longer manned, with colour light control now being in operation between Driehoek and Denver.
