G is for Grand Trunk Pacific Turntable
The turntable now located at Central BC Railway and Forestry Museum was originally built in 1913 by the Grand Trunk Pacific for their new Prince George Roundhouse. It was dynamited from its foundation in 1984, and installed in its present location in 1990.
At 28 meters long and 102 tonnes in weight, the turntable can support over 394,000 lbs! This allowed the mechanism to turn rolling stock around and move it to the 13 rail lines in and out of the roundhouse.
Originally powered by pressurized steam, the turntable has since been converted to run on compressed air which still powers it today.
