Time to weigh the turntable!

As part of our planning for the removal of the turntable from the roundhouse for restoration, a technician from Western Mechanical of Barrie, Ontario lifted one side of the turntable bridge in order to weigh it. A pressure gauge in the line from the hydraulic jack pump recorded the pressure required to lift one side of the bridge off its supports. Oil pressure multiplied by the jack piston area equals the load weight. The total bridge weight was found to be 151,000 lb or nearly 76 tons.
