Express' second locomotive was Union Pacific 951, seen here arriving
at Omaha to take over from the 2312 locomotive.
Artist Bob Lorenz
designed the paint scheme.
plan was to have an E9A and E9B set of locomotives repainted at
La Grange, IL and take over on the train in Chicago. The A-B set
would also help power the AFT (along with a smaller steam locomotive)
in the Northeast during 1976. These plans were abandoned and only
one UP locomotive was repainted for the Preamble Express.
The 951 locomotive
pulled the Preamble Express for the remainder of its 48-state tour.
The crew nicknamed it "Snowbird".
it returned to the Union Pacific and retained its Preamble Express
colors through the Bicentennial. It was the only UP locomotive painted in connection with the American bicentennial.
