Rebuilds
In addition, many other earlier locomotives were rebuilt to Dash 2 standards by numerous locomotive rebuilders and railroad shops.
Among the most popular rebuilds are SD40, SD45, SD40T-2 and SD45T-2 into the functional equivalent of an SD40-2, although the frame, carbody and trucks remain the same as on the "donor" locomotive. In many cases, the rebuilds are identified as, for example, an SD40-3 or an SD40M-2, or an equivalent distinguishing identification. In some cases, the locomotive is identified simply as an SD40-2, although it is clear through physical examination that it is a rebuild. Once so rebuilt, the locomotive enters the owner's fleet as if it were a true SD40-2, arguably the most versatile and reliable diesel-electric locomotive of its time, if not all-time.
Although not as popular as the SD40-2 rebuilds, GP40s, GP39/SD39s and GP38/SD38s have also been rebuilt to the equivalent of GP40-2s, GP39-2/SD39-2s and GP38-2/SD38-2s, so significant were the reliability and serviceability advantages of the Dash 2 line.

Famous quotes containing the word rebuilds:
“Really, there is no infidelity, nowadays, so great as that which prays, and keeps the Sabbath, and rebuilds the churches. The sealer of the South Pacific preaches a truer doctrine.”
—Henry David Thoreau (1817–1862)
