 It is possible, but unproven, that this locomotive also went to Lancaster Gold Mine, since it was of identical dimensions to the other two.Although they were eventually classified as two foot narrow-gauge locomotives along with the rest of the South African narrow-gauge locomotive fleet, they were actually constructed to a 600 millimetre gauge.Historically, the actual two-feet narrow-gauge rail spacing depended on whether or not the track was laid by a metricised country.
