Can confirm, I was at Aga Khan Park & Museum station at about 2:00 PM, saw five trains in the six minutes I was standing there watching. Four of them were headed towards Kennedy, the other towards Mount Dennis.
There was an announcer lady announcing and announcement whenever a train was arriving and departing the station, she said: "The next train to arrive on the eastbound platform is for Mount Dennis." A little buggy since most trains were headed towards Kennedy.
Door chimes sound like the street car ones. Trains were moving quick.
Side window signs read - Eglinton | To Kennedy
Another train had TRAINING CAR written like that in all caps on the front and side signs.
