The road number 4141 was previously occupied by an SD70M, which has since been renumbered to 3778.
The unit was removed from active service due to reduced traffic levels stemming from financial crisis of 2007–2010 and was stored at UP's North Little Rock shop. The locomotive was briefly removed from storage in 2012 and made a round trip from North Little Rock to Chicago, and was then immediately returned to storage. As of September 2017[update], it is wrapped for long term storage at Jenks Facility and shows no sign of returning to service. As of February 2018, 4141 has been moved back outside after receiving cosmetic touch ups to its paint.
