F Units By XO. The restored tower in Mechanicville, New York was a great location prop to capture the scene of Canadian Pacific Office Car Special (OCS) Train 41B passing on October 29, 2018. The power for this excursion was CP 1401 (ex-CN 6541, FP9A), 4106 (ex-CN 6515, FP9A), and 4107 (ex-CN 6526, FP9A), leading the 11 cars of VIPs. This was the first visit of an OCS to the former Delaware & Hudson Railway during CP's ownership, and is the only trip to cover the full length of this portion of the line in the United States from Albany to Rouses Point.
