History
The first Dash 8-40CW was delivered to the Union Pacific railroad in 1990. In total, GE would build 756 Dash 8-40CWs. The Dash 8-40CW was succeeded by the Dash 9-44CW in 1994.
Like most GE locomotives, the Dash 8-40CW saw continuous upgrades over the course of its production. Later model Conrail units were built with split cooling systems for the turbocharger intercooler and engine cooling (previous Dash 8 series had both on the same cooling system). The later units delivered to Conrail in 1993 and 1994 were equipped with GE's Integrated Function Displays (IFD). The IFDs are LCD displays that provide the engineer with the same information previously provided by analog gauges, as well as integrating distance counter and End of Train Device telemetry functions.

Famous quotes containing the word history:
“The history of the past is but one long struggle upward to equality.”
—Elizabeth Cady Stanton (1815–1902)
“False history gets made all day, any day,
the truth of the new is never on the news
False history gets written every day
...
the lesbian archaeologist watches herself
sifting her own life out from the shards she’s piecing,
asking the clay all questions but her own.”
—Adrienne Rich (b. 1929)
“I am ashamed to see what a shallow village tale our so-called History is. How many times must we say Rome, and Paris, and Constantinople! What does Rome know of rat and lizard? What are Olympiads and Consulates to these neighboring systems of being? Nay, what food or experience or succor have they for the Esquimaux seal-hunter, or the Kanaka in his canoe, for the fisherman, the stevedore, the porter?”
—Ralph Waldo Emerson (1803–1882)
