A couple of youtube live cams that caught it.
Virtual Railfan Barstow, the west cam, at 20:20:30.
100 miles from epicenter. Didn't look like much.
Tehachapi Depot Railroad Museum - Tehachapi Live Train Cam 2
Looked worse there.
It's still available on rewind (each cam has 12 hours on rewind).
Trains have been stopped, and inspections are ongoing. Gradually allowing them to move again.
