EMD Dash 2
On January 1, 1972, General Motors' Electro-Motive Division (EMD) introduced its new Dash 2 line of diesel-electric locomotives. All designations of these new models were those of the former models with "-2" added (e.g., the SD40 was replaced by the SD40-2). They all retained the basic specifications of the earlier models in terms of power output and most other features, but introduced a large number of improvements to the locomotives' internal systems, specifically the electrical systems. These were intended to improve availability, efficiency, and ease of maintenance.
One major improvement was a modularized electrical control cabinet, allowing maintenance by unit replacement and the use of common parts. These concepts were first tested on the DDA40X.

Famous quotes containing the word dash:
“More rapid than eagles his coursers they came,
And he whistled, and shouted, and called them by name:
“Now, Dasher! now, Dancer! now, Prancer and Vixen!
On, Comet! on, Cupid! on, Donder and Blitzen!
To the top of the porch! to the top of the wall!
Now dash away! dash away! dash away all!””
—Clement Clarke Moore (1779–1863)
