# Heritage unit

A heritage unit or commemorative locomotive is a railroad locomotive painted in an honorary paint scheme; usually the paint scheme is that of a now-defunct railroad that merged with or was acquired by the locomotive's owner.

## Among North American railroads

Heritage units are popular among North American railroads. As of 2023, all major Class I railroads have official heritage units, except for BNSF Railway.
The Union Pacific Railroad painted six EMD SD70ACes in stylized paint schemes of six of its predecessors between 2005 and 2006. The Norfolk Southern Railway did the same in 2012 with 20 of its locomotives for its 30th Railroad Anniversary. 10 of them are EMD SD70ACes, while the others are GE ES44AC units. For its 40th anniversary in 2011, Amtrak painted four GE P42DCs, a P40DC, and an EMD F40PH converted to an NPCU into its older paint schemes. Several more were painted for its 50th anniversary in 2021.
In 2019, the Canadian Pacific Railway, now Canadian Pacific Kansas City, painted nine EMD SD70ACU units in a maroon and gray paint scheme with a different font style. In late 2020, the Canadian National Railway revealed five new heritage units after they had been first spotted a month earlier. These included four GE ET44ACs and one EMD SD70M-2. They were painted in honour of the 25th anniversary of CN's initial public offering. Beginning in 2023, CSX revealed its first of many heritage units, ES44AH 1827 with a Baltimore & Ohio paint scheme.
