It was retired by UP in 2020 and donated to Railroading Heritage of Midwest America last year where it will undergo restoration. Hop aboard our "blast from the past" story and enjoy this powerful locomotive's trek across Nebraska. #nebraska #trains #trainspotting Union Pacific Railroad | Nebraska Stories | Facebook

In fact the Northern Pacific had 47 of them, designated as Z6s, Z7s & Z8s built by ALCO between 1936 and 1944.
