I'm a track hound so I took plenty of shots of the turnouts along the way. We are about to cross the switch to the LRT Lead which runs along Wright Ave. Like many of the switches in this area, it does not have guard rails, instead there are raised lips on the outside of the frog to keep wheels moving in along the correct routing. This design is intended for slow speed use.
Having said that, the diverging route does have a guard rail for the tight curve that extends all the way around onto Wright Ave.
I did notice that the BNSF has installed a few switches like this in the new BNSF Port of Oakland terminal. Those switches spend most of their time handling big thrid gen units and intermodal cars so the design is not limited to light track.
