I have a Lionel 2004 Catalog 6-24529 F3 Santa Fe Warbonnet that at normal speeds stalls in Fastrack Command Switches and then a second later resumes set speed! All my switches are 048 and 072. The 048 Switches are remote and NOT Command switches just to clarify. Note: This model was fresh out of a unopened box, factory sealed as of July 2020. Sat on the shelf for a few years!!! It's a beautiful model, just doesn't run very well. I looked for months until I found this TMCC F3 Warbonnet!!! I did check to see if the 3rd rail rollers were both getting power (18vac), and based on my check they were. Any ideas what the issue might be?
