The SD70ACe is the latest in the line of EMD's "70" locomotives, an evolution of the SD70MAC, although its
radiator design harkens more to that of the SD80/90 body. The SD70ACe has been designed to fit the latest
EPA standards and regulations, and sports 4300 horsepower. The Union Pacific has currently put in the largest
purchase order for these units, and as a display of respect for the railroads it has incorporated, has produced
six "Heritage" style painted locomotives with road numbers designated by the year they were merged into the UP.
My George H. W. Bush Locomotive #4141. Technically a Union Pacific Locomotive, painted in the multi-tone blue,
silver and white striped color scheme of Air Force One and the name of the G.H.W. Bush Presidential Library and
Museum on it's side. (SOLD)
SD70ACe Union Pacific Heritage Locomotive, #1989. 1989 being the year that the Union Pacific and the D&RGW merged.
