The faculty at Delano was just off the UP, and had their own on site switcher. Originally an SW10 (see below), and more recently a GP22ECO (I believe). The SW10 was moves to somewhere up in Washington (dont remmeber where off the top of my head).
The SJVR was never involved at Delano (as far as I know). That said the SJVR does handle some decent reefer traffic, with the largest amount (to my knowledge) coming off the Huron/Leemore Line (see below below). Leprino Foods who I believe make a lot of cheese has two large facilities on this branch, one just west of Leemore, and one in Leemore.
Hopefully others can add to/correct this as it's sadly been a few years since I've been out and about in the San Joaquin Valley.
