Running American Flyer SP&S freight 05-04-2026

This video features the completed SP&S ALCO PA-PB diesel set pulling a mixed freight consist. This was a fun project. The early AF Santa Fe chassis have the axle bearing inserts. The B unit uses the same frame and chassis with axle bearing inserts. No drive gears on those axles though. Even with the small armatures - fields, this pulls well and has enough traction to handle the grade. Thank you all for watching.
