In order to enable the train and locomotives to remain intact for the trip to New Jersey over NS, UP removed its own cab signaling on SD70AH’s Nos. 1943 and 9082 in Council Bluffs and installed Norfolk Southern cab signals. This would enable No. 1943 which is specially painted to honor U.S. Armed Forces to lead on NS, with No. 9082 also equipped to lead in case of a failure with No. 1943 en route. As a result, Union Pacific had to add UP No. 2752 from Council Bluffs to Chicago since this route is equipped with UP cab signals.
At Proviso, UP removed No. 2752 from the train, which continued east from Chicago as Norfolk Southern train 066-30. It’s expected to return west from Croxton on June 4 to Council Bluffs.
Trains News Wire is awaiting comment from UP.
