I've seen a few videos & reviews of the engine but not one in the Alaska RR livery so I thought I'd post one. This is one impressive engine. Heavy (maybe even heavier than the VL BigBoy), great deep base sound system and smokes like crazy. One thing I did notice that after I switched it to Sequence Control Mode (at :55) the horn seemed to be out of sync between the Engine and Tender (at 1:00). If this is intentional doppler effect? If so then close up it doesn't sound very good.
Enjoy.
