This BlogTO post reminds us that there was a time when train travel was the norm in Toronto. But, as the photo of Moore Park Station shows, even in 1909 some of the rail lines had already falled into disuse. What's with the turrets? Don Station has one too; maybe it was the same architect.
Of the stations from the early 1900s, Don Station is one of only two that were saved. It has been restored at the Toronto Railway Heritage Centre (the web site could use an update). The other station is the North Toronto CPR Station which is now an LCBO outlet and is the largest liquor store in Canada.
