I have a terminology question. When departing St Cloud, MN on the Empire Builder route, someone on the radio says "Here comes the runner", you may think this means there is someone who missed the train who is running after the train, but this is not the case. Every time crews depart St Cloud, if they are on time or late, no matter what, after they have highballed out of the station and are moving in either east or west direction, someone will say "Amtrak here comes the runner". I think this is the Engineer or AE. Then the conductor or AC, will say "Amtrak highball the runner", I have not noticed crews doing this at other crew change points. They always mention this "runner" after the previous conductor has given an OK roll-by inspection, and after the Ar/Dp times are stated on the radio. I have a video of this "runner" being mentioned as the train departs St Cloud. There are also many videos on YouTube that this "runner" is mentioned on the radio. If there are any employees that know what this term means, please; enlighten me. Thank you.
