The Loops in the Rogers Pass were a clever way to reduce the grade of the Railway at the West end of the pass. As the tracks descended from the summit of the pass they went through a series of snow sheds then crossed Loop Brook twice and Illecillewaet River three times is a series of loops that reduce the grade, and avoiding some avalanche areas. The loops dropped the elevation of the track by 500 feet, and added three miles to the length of the line.

When first built the bridges were huge timber testles. After a few years as much as possible was filled with dirt and rubble and new bridges supported by stone piers were built by Italian stone masons.
These two shots were taken from about the same place. They show one of the original trestles and the stone pier bridge.
After the opening of the Connaught Tunnel in 1916 the tracks all the steel parts of the bridges were removed as the trains now went under the Rogers Pass not over it.
These two pictures taken in May of 1995 show what remains now of one of the Loop Brook bridges. The stonework is very solid and the pylons are an lasting memorial to the workmen that built them
These are the remains of 28 shed which was a fairly small stucture. It was the last one heading west out of the Rogers Pass before going over the first crossing of Loop Brook and the start of the loops.
