Today's HO incident:
From Athearn Genesis - HO Scale - EMD GP40-2W - DCC Ready - Canadian National (CN) -#9638,
new/in-box(Jan 2014).
OOPS! By mistake, I grabbed the wrong box, it was sitting beside the GP40-2L version(the model I had intended to purchase); but, it contained the GP40-2W version. Both boxes, and versions, look very similar...
Apparently, the L(light) version is only slightly, visibly, different from the regular, heavier prototype, the GP40-2W. I really like the model I test ran and brought home, by mistake; I will keep it...
BTW, my previously purchased Athearn Genesis CN GP38-2W was by accident, too. I had been intending on getting the GP40-2L version; same type of confusion... but, it's one of my favorite models, now. I especially like the twin, roof-mounted, extra fine radiator fan grills; very nicely constructed...
