CalAnon here. I can tell you that there has been an increase of trains heading west to East. On my daily commute, which varies time day to day, I often see long, long trains filled with double stacked shipping container cars and big rig trailers. These trains are so long they often have 4 engines in front, 2 or 3 in the middle and several on the end.
It’s always a long wait at the crossing.
