I was checking out an open area a bit north of Pottery Road, it's about 11 or so. After grabbing a couple of shots of a bridge, I was in between open sections and could hear a horn blast further north, followed shortly by activating signals at a foot trail crossing. I had to sprint back to an open area and luckily caught VIA Canadian #2 passing through. Odd setup with 4 power units up front lead by 6442, 6410, 6456 and 6441 in that order. Then the shorter winter consist of 10 cars.
After poking around the trails for a while, I wound my way back near the line and found the north signal showing red, and the south signal green. Nothing had gone north so either something was heading southward or track maintenance was happening further up the line.
I got a call that my car was ready for pickup and headed back up the trails to the dealership. Just before passing the waste treatment facility below the Redway Loblaws, a diesel sounds on the line. This is about 12:30. I'm a fair bit away but open the camera expecting a CN freight unit.
Surprise! It's another VIA! A more modern unit with light cars making it's way southbound. Not what I was expecting at all. I know of no other VIA units using Bala on a regular basis outside of the Canadian. I was too far away to see any numbers.
So two interesting catches. A 4 power unit short consist Canadian and a light modern Via unit.
Update: Apparently there is some problems with a building near Union Station in danger of collapsing onto the tracks. The Canadian was delayed and some other trains rerouted, notably VIA 84 out of Sarnia. This is most likely #84 as the timing fits.
