Always short on power, Canadian Pacific would often lease GO (Government of Ontario) commuter locomotives for weekend use. Here we see the 514 and the 510 leading Windsor to Montreal train 904 out of the CP's Windsor Yard. Trailing are CP 4218 (C424), CP 5001 (one of two GP30's on CP), CSX 3115 (GP30), and C&O 3006 (GP30). Sept 30/79
