What about squirting some(red n tacky) grease in the gearbox? It sounds like gear noise to me.
It appears you have the Loco suspended in mid air. Between no weight on the drivers , and running it at lightning speed I don't know that the gear noise is detrimental.
See if the grease helps.
Hopefully this Loco was greased previously along the way seeing as its 18 years old.
