I got a chance to chase the Pig Train through the Cantara Loop on down to Castella this last week. It’s called the Pig Train because of the Piggyback configuration of the trailers on the flat cars. Back in the ’50s-’70s, Southern Pacific even had special trailers with a cute cartoon pig on them for this service.
These days, it seems, there are mostly ‘Swift’ trucking co. trailers on this service.

2) Cantara Loop
I have more pics and dialog about this on my updated website tunnel13.com
