Well, here is what I can pass on... I can't say its all that recent, and honestly there are probably some (or a lot of) inaccuracy. Hopefully someone can fill in for both of us...

The Job that worked the Westside Line out to Oxalis and the Riverdale Branch down to Burrel is the 708 Job. They work out of a small "yard" at Crayold just west of the UP line through Fresno. They run Monday through Friday with an on duty time around 07:00, and often tie up around 13:00-14:00. They typically alternate days on the Westside Line and the Branch. It is my understanding that much of the traffic on both of these lines is rather seasonal, and they will only run as far as the days work warrants.

As for industries here is what I have in my notes. Some of these may no longer be active rail shippers or may no longer even be in business:

West Side Line (Fresno - Oxalis):
---------------------------------
Kerman
- Helena Chemical
- Looks like several more industries here too

White's Bridge
- Holly Sugar

Firebaugh
- Farmer's Firebaugh Ginning
- Tomatek, Inc.
- N.F. Davis Elevator

Oxalis
- Western Farm Services


Riverdale Branch:
-----------------
Helm
- Simplott
- ConAgra

Burrell
- Foster Farms (may no longer be receiving rail service)


I hope this helps a bit, and as said before, I hope someone with more current info can pass it along.
