An old topographical map of the Mexican Central Railway, taken from Wikipedia

Grooves embedded deep upon the contoured land
potent water ways of vital twists and turns
Each near-insignificant in form, evolving
but sprung forth necessary, flowing from function

Old channels run deepest
and though dry now, they bide their time
awaiting frenzied blood to pump, pump
To course, raging back into the zeitgeist

Clang clanging metalworks upon the flat land
straight lengths of steel, angles unnatural
Each piece an exacting cost of toil and ore, connecting by necessity 

Young minds young eyes, reckless ingenuity
bend matter to will as on an anvil
a frenzied thirst for fortune, they drink and drink
On command, the milk courses out from the teat
