When the WC first bought the ex VIA F's for Agawa Canyon service they tended to stay in passenger service, even during the peak fall color season when the tour train could run up to 30 cars. During Sept. and early Oct. it wasn't uncommon to find five F's struggling along on these monsters. That only lasted a couple of years though as the F's were having failures and WC started to use SD40-2/SD45/F45/FP45/GP40 units during the fall color season. This train 4 has 1751, 1754, 1752, 1755, 1750 leading the tour train southbound passing Searchmont station.
