The North American Class 1 railroad company said that, combined with upgrades planned for its railyard infrastructure, the investment in the locomotives would exceed $100m.  

Union Pacific is buying the electric locomotives from Caterpillar subsidiary, Progress Rail, and Wabtec, which provides transport equipment and systems. The rail provider said that the first units would arrive on-site at railyards in California and Nebraska in late 2023, and the order would be completed by late 2024. The locomotives will be tested for performance in cold and warm weather and will then be assessed for their capabilities and for broader deployment, according to the company.
