Western Railroad Discussion > Question on Santa Ana Pic. Any help please?

Stumbled across this pic. Back in 2011, I was waiting at Santa Ana and caught this. Question is: Are there UP customers south of Santa Ana and I take it UP has trakage rights?  Looked around on the net and couldn't find anything except for Y168.
As for Y168 it was built 41 years ago this month for the SP.  
-Thanks always in advance -Matt

For the UP this is part of the Santa Ana Industrial Lead which uses the SCAX (Metrolink) track from Anaheim to Santa Ana. It goes back to UP trackage just south of the station and then goes almost 7 miles to Costa Mesa.

Here's a link to the Google maps location of the connection.

The UP trackage between Santa Ana and Costa Mesa came into the UP system with the 1996 merger with Southern Pacific. The track from Santa Ana to Dyer (once the site of a sugar factory) is about 2.3 miles from Santa Ana junction (CP Fourth Street on Metrolink) and was built by the Santa Ana & Newport Railway. The SA&N was acquired by the SP in 1899. A Pacific Electric line connected at Dyer and ran to Costa Mesa, this was part of a PE line that once ran from Santa Ana to Huntington Beach. The PE trackage was included in the SP with the 1965 merger of the PE into the SP.

The line was a good freight line at one time with sugar beets to the sugar factory and industrial development along the PE in south Santa Ana and Costa Mesa. A Los Angeles Times printing facility was once a major business on this line. The trackage rights between South Anaheim and Santa Ana started in 1989 when the SP line between those point was abandoned because of a freeway widening project.

Today traffic is much lighter with most industries gone, including the sugar factory and the LA Times. The UP comes to Santa Ana normally twice a week on Monday and Wednesday mornings. The major customer is the Behr Paint Co. at Costa Mesa. A couple industries get covered hopper of plastic and at times there is staging of cars for future delivery are the other sources of traffic.

The UPY168 is a GE B-Boat rebuilt into a remote control receiving unit. (a large box car).  To be coupled to an engine wo remote control receiving capability, to make it remote capable.   Fuel tank, traction motors removed, it's pretty ugly.  I think they are slowly all getting scrapped now.
