My train got stuck behind a very slow moving freight train while crossing Nevada. With a GPS app, I tracked our speed at 2 MPH for nearly 30 minutes. I don't believe we ever exceeded 30 MPH at any time between SLC and Reno. I'd look out a window and see cars and trucks speeding along at 80 MPH on nearby I-80 while we were creeping along 20. And, of course, we were already 2-3 hours behind schedule. We ended up arriving in Emeryville 3.5 hours after the expected arrival time.
