MoW Train south through Santa Barbara

[NHV 669]

Any idea on the purpose of the train I just saw? Waited for NB and SB Amtrak trains to pass, then departed south at roughly 1150. 5 engines, about 65 cars. Two tanks in front, the rest was a combination of low gondolas, and some box trucks/assorted MoW equipment/empty flats

A systemwide production tie gang train used to move the rail mounted equipment and support vehicles from location to the next work location,
may have been a move to the pickup location of the equipment from the "start" location (Drop off).
