UP upgrading Phoenix west sub. Don’t count on them to continue on to Yuma. Evidently traffic up on line so UP may consider it needing to be upgraded for traffic level.
Phoenix according to UP has a 5 or 6 to 1 ratio of inbound loads to outbound loads.
UP probably wants to spend their money on the Sunset double tracking effort. $9M is not a lot to spend on 40+ miles.
Only if a lot of inbound traffic to the Phoenix west sub occurrs and much originates west of Yuma would UP want to reopen line to Yuma to reduce back tracking to present Sunset route.
