What does one do with a jumbo sized box of bad locomotives?

mix up the pieces and give half away to differing recipients, lol

 

Try reaching out to Sacramento Valley NTrak / NRail.
Maybe someone there will want to take the entire lot of locos off your hands.
According to their FB page, they meet about once a month in Rocklin - which appears to be in your general vicinity.
Contact person is Jeff @ 916-five-two-four-seven-eight-one-two.

 

I know Jeff very well.
