At 10:30 this morning both air drive motors were tested in the Western Mechanical shops in Barrie. The motors were extensively rebuilt and functioned flawlessly. They have amazing torque. An artificial load simulating the bridge and locomotive weight was placed on the motors by applying the mechanical brakes full on. The motors handled this load at 25% air supply. The four beat per revolution exhaust sound produced by the D valves were sheer music.

Kudos go to Paul of who did the critical machining, valve timing, and final calibrations. He replaced all of the babbit surfaces and gravity oil feeds with lubrication fittings so that maintenance becomes foolproof and pollution from excess oil is eliminated. The base frame was entirely rebuilt. The motors are scheduled to be joined to the turntable and the turntable placed in the pit next week.
