BNSF Passenger Extra 9300 East?

[eolafan]

This afternoon I went out to my favorite railfanning spot, BNSF Eola yard and braved the heat for a few hours. During my time there I heard the East End Dispatcher speaking with a passenger extra he called "BNSF Passenger Extra 9300 East" and I traveled east into Naperville hoping to catch him but no luck. Does anybody know anything at all about this train, type of power, cars, etc.?

Thanks to all who can help.[:D]
