A per-mile payment for railroad track led one company to bend its route into a bow

the gist

When Congress agreed to pay the builders of the first US transcontinental railroad for each mile of track they laid, it created an incentive that rewarded length over sense. Thomas C. Durant of the Union Pacific Railroad lengthened one section of the route so it curved into a bow shape, adding miles of track that were not needed. The rule was meant to speed up construction, but it encouraged the builders to maximise payment rather than the most direct line. The railroad was completed in 1869 at Promontory Summit in Utah, linking the coasts by rail.

so what

It is a classic example of a perverse incentive, where a reward designed to achieve a goal ends up encouraging the opposite. The same trap appears in contracts, bonuses and public policy today.

fun fact

The first transcontinental railroad was completed at Promontory Summit, Utah, in 1869.
