I used to live in Toronto, and as far as I know, there's no second level on the subway, maybe by "train" with second level, the write meant "street car" or "tram", right?
We got on the train in Oaksville, got off at Union, and I
brought (c)her up to the office. We had lunch and I picked
up the bill. Back at Union, on the platform, we learned our
train was delayed due to snow. It was bitterly cold. A
woman approached us
She took a shawl from around (a)her neck and placed it on
Jenny’s lap with great care. The train arrived, we all piled
on, and the woman went up to the second level of the car.
Once warmed up, I took the shawl off Jenny, folded it
neatly, and planned to return it. When the woman came
downstairs for (b)her stop she would have none of it, saying
it might come in handy someday.
It's more likely that the train had two levels; maybe it was a double-decker.
