Hi Gordon
J Lister's medal roll states he was a Platelayer. Roll date 4th June 1904 Durban.
Remarks column - reconstruction of track.
Perhaps he was promoted to Conductor at a later date.
Platelayer-
Inspecting and maintaining the track, including all its component parts such as rails, sleepers, fishplates, bolts, etc., are the chief responsibility of the platelayer.Their duties include greasing points, and generally watching for wear and tear. When sections of track require complete replacement, larger teams of platelayers work together, and today employ a range of labour-saving machinery for many of the tasks traditionally undertaken by hand by platelayers.
