This rendition of the Freight Train has been the fly for sockeye & chum this season. I have added some Crystal Flash as an under wing, changed the wing to bear hair, and placed a thorax of dubbed blue / purple sparkle material directly behind the wing material. The gob of dubbing helps keep the wing & hackle bulging out a bit when the fly is fishing and I believe the fatter profile helps.

This was the first sockeye of the season, caught 4 weeks ago. The fly from the picture is the one in the fishes jaw.
More on the same fly, all males;
Chum salmon have been plentiful and here's a nice fresh one hooked to the freight Train also. All together the pattern has landed in the vicinity of 35 - 40 sockeye and probably the same number of chum.
Whether you plan for Alaska or the Great Lakes rivers this pattern may be a good choice for your box.
