While trainwatching earlier this week, I heard the BNSF dispatcher tell a manifest in the siding that he was being held for a Silver Z train. Does anyone know what exactly this is? Does BNSF have different levels of Z train service now?
The ever elusive "Silver" or "Highlighted" Z-train is nothing more than a behind schedule Z-train. When a z-train (or any train) gets far enough behind schedule or the crew is running out of time to legally operate it, it will become "highlighted" (just so happens to be a silver highlight) in the computer, making it the highest priority train on the railroad. Everything gets out of the way for a Silver Z.
