Simcoe St. used to end at Station Street at a tall brown brick “bunker” that I assume was used for railway storage or something. It was demolished when they needed to start digging under the rail corridor in 2007. On the south end, north of Bremner, Simcoe was an unused dead-end street ending at a roughed-in underpass full of dirt. I’m not sure if Google Streetview goes back far enough to show this (2006).
