Caption: Thanks to some excellent information from a few friends, I was able to make it out to Etobicoke to witness the mainline test run of the Union Pearson Express units 1001, and 1002. They were given a permit to occupy tracks 3 and 4 on the Oakville Subdivision between Canpa and Gardiner. During the few hours of testing, they ran the train back and forth between these two points several times. I believe they tested the doors and made a breif stop at Mimico as well.
