G.E. units at Bensenville?

Last evening while driving south on I-294 past O’Hare in Chicago I passed over the leads to the CP Bensenville yard (former SOO/former Milwaukee Road). There was quite a long string of G.E. units (ten or so) sitting where there are normally a few (three or four) units. What may be going on as this is highly unusual?

GE’s at Bensenville is no big deal in and of itself when you consider the number of AC’s and GEVO’s on CP’s roster. Ten at one time may be a fluke based on operations and timing.

I know CN has been sending lots of power north in preparation for fall harvest traffic and it’s possible that CP is preparing to do the same. I’ve seen trains with upwards of 6 units commonly and north of 10 a few times.
