Caption: Every excellent morning starts bright and early with a good night's sleep, an uneventful train ride in, and a brisk walk from Union Station all the way to Bathurst Street to shoot a gazillion GO F59PH units handling the morning rush hour traffic. One of many seen that morning, GO Transit "Triple Nickel" 555, cruises into the Union Station Rail Corridor on eastbound Lakeshore line train #452, while in the distance, brand new MP40PH-3C 605 is snaking through the crossovers at Strachan Avenue on Milton line train #152.

The few newly active MP40 units at the time would be regularly assigned to Milton line trains, enabling GO to run longer 12 car consists to make up for the lack of track time CP allowed to run extra trains. The limiting factor on F59PH units like 555 was the HEP, which could only provide power for a maximum of 10 bilevels.

GO 555 would be made surplus by the second flood of new MP40 deliveries, a fairer unit in GO's eyes, and unlovingly shed with 9 other F59 siblings to AMT/exo in 2011 (renumbered as AMT 1348). GO would court and woo back the favour of 555 and three other units in 2026 for their future "F59 Renaissance" period, bestowing her the new number of GOTX 580 (restoring her to her former glory as 555 however, would be a much fairer number of prestige to bestow upon one so unwillingly cast off, only to be swept back close to Metrolinx's bosom in their time of need).
