You know what? They really wait for people! I first noticed it when Boris and I were walking with Nadia to the Jarvis station. I was sure that we would miss the train, but it was still waiting for us when we got up on the platform. I attributed it to the fact that we had a small child with us, and it was Saturday when the trains run less frequently, but I was wrong.
On multiple occasions, the train waited for me when I was close enough to the station so that the train operator could see me from above.. Each time it surprises me and makes me feel very grateful :). Today, there was a train running in the opposite direction, standing at our stop and blocking the view of the street. Granted, the folks on the train could not see me, and they took off just when I was almost on the platform!
