From the start of the twentieth century, southern African railways con
veyed vast numbers of miners to and from the Rand gold mines in a flui
d and contested political and economic setting. The need for a large,
continually replenished and low-cost workforce was met by tapping new
and distant labour pools. Railways mobilised miners by offering relati
vely inexpensive, quick, long-distance mass transport. They also curta
iled desertion and exhaustion associated with walking. Yet the interes
ts of state-owned railways and mining capital were not completely harm
onious. The contribution of trains to migrancy was limited by the geog
raphy of a railway network built for other purposes, by geopolitical r
estrictions on recruiting, by complex and discriminatory tariffs, and
by the inefficiency and disunity of railway operations. In the 1930s t
he reach of railways was enhanced by flexible road transport; thereaft
er, non-rail modes of transport operated by and for mine-labour agenci
es, conveyed an increasing share of the stabilising mine workforce. Ra
ilways facilitated massive migrancy but might have been even more effe
ctive in a better orchestrated and narrower economy. Essential in the
first twenty years of industrialised gold mining, railways first entre
nched and then prolonged migrancy. Railways were also significant in t
hat they did more than temporarily relocate inert labourers: migration
by train was, in addition, a socially and symbolically charged episod
e.
