As I mentioned in my previous post, I visited Castle Frank Station frequently since it was an equal distance from my old apartment to Sherbourne.
The classic TTC tiles in Castle Frank have the same peach/maroon colour scheme as Keele Station.
On your way to the platform you'll find tight corners.
As well as wide stairs.
The station is relatively open to the outdoors with its exits, so it gets quite chilly during the winter (and very muggy in the summer).
The next station is Broadview.
