I was listening to the Tehachapi dispatcher channel last night and heard some chatter about DPUs acting up on a UP manifest coming out of Caliente. A while later that train put 5 cars on the ground in Bealville. No injuries or hazmat involved, but they're still cleaning up this morning. I heard speculation of a pinched MU cable, but that's not confirmed.
Made for some interesting listening last night. Here's the link, if you're interested:
