Caption: As Ontario Northland's "Northlander" test train has just entered the Union Station Rail Corridor, ACPU #220 (former Amtrak F40PH) slips under one of the remaining 1930s-era signal bridges slated for replacement in the very near future. It was quite a treat to be able to get out and catch this rare movement, and might end up being the last time any ONR equipment passes under these classic relics unless they plan on doing more tests in the next few months.
