According to one article, the dispatcher knew but did not alert the engineer. I understand the dispatcher was fired.

If you ever fall over in public, pick yourself up and say “sorry it’s been a while since I inhabited a body.” And just walk away.
Just to clarify the action of PCS on Union Pacific locomotives. When CNW was merged I issued the project to modify CNW locomotive air brakes to UPRR standards. PCS opens and locomotive consist power is immediately reduced to idle at the initiation of a penalty application, brake handle placed in emergency position, or the conductor's emergency brake valve is opened. On an emergency brake application from the train PCS open is delayed 20 seconds. The 20 seond delay is intended to permit the engineer to bail off the locomotive brake and use the throttle to keep the locomotive moving away from a train separation. If the engineer places the brake handle in emergency position PCS will open instantly.
All UPRR locomotives retain dynamic brake during penalty or emergency from any source, PCS will open but has not effect on dynamic brake. There are two reasons, keep train slack from running out and permit the engineer to retain dynamic brake on decending grades when all available braking is needed.
