The newly arrived individually controlled 3rd Rail SF Yellowbonnet F7A-F7B units with stainless steel side panels sparkle in the low horizon light of the Pacific NW. They each have two automatic firing couplers suitable for freight yard switching. Next to them are a " mued " up set of previously released 3rd Rail SF FTA-FTB with whiskers. They are closely coupled with a drawbar and are designed to be operated as one unit.
The weight of each unit is accurately measured to the nearest gram and the drawbar pull was dynamically measured up to wheel slippage.
F7A 2013g (55. oz) 1.35lb+/- 0.20 drawbar
F7B 1916g (51.5 oz) 1.52lb+/- 0.20 "
FTA 1953g (53. oz) 3.00lb+/- 0.6 combined two units drawbar
FTB not weighed
The combined 4 engines have not been tested together yet but should be a nice consist to pull a heavy 12 car passenger train up grade with a stop at a station on the way. Or a very long freight consist of lighter cars.
I don't have the GGD El Capitans, but those Red/SS Silver are going to look spectacular pulling that consist. Looking forward to seeing many other roads posted as UPS rolls out in other areas.
