Re: Dual gauge trestle

Nigel Phillips

Hi all,

Found some interesting information on trestles used on the Gault lines in Southern Alberta. The line between Lethbridge and Dunmore junction had a small trestle over Persons Creek, with 6 pile bents. Bents (probably not the originals) are still in place along with some CPR track. The St. Mary Railway had 3 trestles, the one at Spring Coulee being reported as 685 feet long. The one over the St, Mary River near Cardston was sandwiched between 3 Howes Truss bridges over the river channels, the bridges being reported as 85 feet for the north channel. and 2 x 150 feet for the south channel. If that is not a typo (150 feet total with 2 spans of 75 feet?) then that was a very long Howes Truss. The crossing over Pothole Creek east of MaGrath was a low level trestle bridge, which from the old track right of way on Google Maps would have been about 75-100 feet long. If double gauged it would have been during 1907.

The bridge over Arkansas in Salida was dual gauge. Yes Steam plant on south side was dual gauge as well as a track in the marble monument facility. 🚂👍Fz
