I just saw a notice that Kato will be doing an N scale run of the EMD SD70ACe Union Pacific #4141 “George Bush 41”. Walthers is taking preorders; the Kato site lists the DCC versions to be shipped in August 2019
With LokSound and DCC

DCC non-sound

Walthers also lists a standard DC model as a “special order”; the Kato site indicates a release in July 2019

The Kato site does not list an HO scale version of this model
