This was an odd mix consisting of my BLI AC-6 Cab Forward and my friend Art's vintage Rivarossi AC-12 Cab Forward equipped with Tsunami decoder. They are pulling Art's Pacific Fruit Express reefer consist over the mountains at the Logan Valley Model Railroad club layout.

I also missed that wheezy air pump noise the Tsunami decoder makes for AC-11&12's. It's a cool effect.
