PTC test train?

Saw what I later found out to be a PTC test train heading west thru Wheaton on UP/W today, using a nine car Metra set of equipment, running right behind 31. From what I could discern from radio chatter, it seemed only to go as far as West Chicago; not sure if it made it to Elburn. PTC has been active on the Geneva sub for at least the last 7-8 months, not sure what this was about.

Anybody got more details?

They were testing some software upgrades for PTC. The next day the ran a test train up to McHenry.
