What happened to the "Pacific Fruit Express?" the joint venture between the former SP and their current owner UP. You still see the cars, some with the chutes for the ice. My impression was it collected fresh produce up and down the Central Valley and delivered it posthaste to points east. Made obsolete by subsidized interstate trucking?

UP is still in the refrigerated freight business. In fact, they've been expanding their fleet fairly rapidly. They currently have 3500 50' refrigerated boxcars and 1500 64' cars (all 1500 64' cars have been purchased in the last 5 years). They also carry more than a small amount of refrigerated cargo in containers on their intermodal trains.

"Pacific Fruit Express?"

sounds like the plot of "east of eden"
