Then, then and now photos featuring the Flett Tunnel, which was located on the former Grand Trunk Pacific Lake Superior Division/CN Graham Subdivision. It was the only tunnel on the line and was situated near Finmark, ON at Milepost 39.8/10.6.

There is only one known period photo of the tunnel, which was taken in 1909, shortly after the line opened in November 1908. It shows the western portal, taken one-third of a mile away from the top of a nearby rock cut. The trestle in foreground was infilled approximately 10 years later when the line was part of the Canadian Government Railways.

Sadly, the line was abandoned by CN in 1994, and the second set of photos were taken shortly thereafter in 1996. Today, the tunnel is one of the most visited former rail locations in the area (though a permit is required from the forest management company that now owns the line). Due to the vegetation growth, the view of the 1909 photo is impossible replicate.

Few people are aware however, of the tragic history of the site. During its construction, a blasting accident on September 19, 1906, claimed the lives of three men; Henry Parvianen, 23, Nestor Rajala, 48 and Peter Ventilainen, 23. In an unfortunate twist of fate, the circumstances of the accident would be repeated six years later at another area tunnel near Macdiarmid on Lake Nipigon.
