Performance
Like the SD40-2 the GP40-2 has a reputation for reliability, and many are still in use. Changes such as the modular electronics system improved reliability over the GP40. Their high power-per-axle rating suited them to high-speed service rather than low-speed drag freights. The oldest GP40-2s are well over 30 years old, and many (notably GP40-2Ls) have been retired from Class-1 railroads and sold to regional or shortline railroads.
With the usual 62:15 gearing (65-70 mph maximum) EMD rated the GP40-2 at 55,400 lb continuous tractive effort; for compatability with other units most (all?) had the PF21 module that reduced horsepower below 23 mph, bringing the minimum continuous speed down to 11 mph.

Famous quotes containing the word performance:
“Still be kind,
And eke out our performance with your mind.”
—William Shakespeare (1564–1616)
“What avails it that you are a Christian, if you are not purer than the heathen, if you deny yourself no more, if you are not more religious? I know of many systems of religion esteemed heathenish whose precepts fill the reader with shame, and provoke him to new endeavors, though it be to the performance of rites merely.”
—Henry David Thoreau (1817–1862)
“There are people who think that wrestling is an ignoble sport. Wrestling is not sport, it is a spectacle, and it is no more ignoble to attend a wrestled performance of suffering than a performance of the sorrows of Arnolphe or Andromaque.”
—Roland Barthes (1915–1980)
