Caption: This image should appeal to those interested in the local history around Dundas. Currently, if you look over the side down into the valley town of Dundas from up on the Peak, you will see a modern upper-scale subdivision just below the CN mainline approximately Mile 4, Dundas Sub. This image predates all of that. The area once was the location south side of the tracks for quarry operations, limestone & dolomite/dolostone mostly; and the image is of the former Dolomite Refractories Ltd operation that existed there from 1945 to early 1977, after which Steetley took it over. The view shows the company switcher with a gondola of containers being loaded with dolomite. Perhaps this is destined for Dofasco? (Dolomite can be used as a flux for the smelting of Iron & Steel)Perhaps it is being shipped out to a marketer of potting soils or the like; dolomite is also used as an acid neutralizer. Many uses. The making of cement is another. This area also stockpiled crushed stone from the limestone quarry above (Canada Crushed Stone) which was used mainly in construction materials. Out of sight is rail connection to and from CN as well as a connection to the TH&B which at one time ran thru the valley joining the current trackage at Aberdeen Yd in Hamilton. All this is gone, and looking around today, one would not realize it ever existed. Comments/corrections appreciated.
