I hadn't noticed that the bells were replaced out in Byron. That's too bad! At least they left the "triangle" gates intact.
Just checked the Google Maps image of D Street in Antioch. Unfortunately, it looks like UP has replaced the "triangle" gates with newer gate mechanisms, but left the old teardrop bells.
Here is a link to the Google Maps image:

It has been quite a few years since I've seen a train down this far on the Mococo, with the last one about 8-10 years ago. UP still maintains the signals, though.
There are some old Griswold cantilievers and gates just outside of Byron, on Byron Highway. These are also on the Mococo line.

The flashers are not original, though. Those were replaced about 10 years ago.
