Success... the look, the feel, the "click" when something just works, that's the attraction for me, re: O gauge model trains. I've found that some things, i.e. certain nicely detailed locomotives, just have what I'm looking for...
I was working with a good group, on 3 rails, earlier this afternoon; and I noticed that one particular unit had the look that stood out, that matched my taste buds, considerably more than the others.
In this particular instance, the "clicker" was a MTH Premier CP AC4400CW, wearing the 2 flags livery. I'm a faceshot man, and this CP unit has the look that clicks, for me.
It seems, sometimes, low mounted number boards, a low mounted headlight, on the short hood; and, a standout paint job, that can"click"/work for me.
I never see much posted about GE's AC4400CW models; if you like GE's AC EMD killer, then you might want to take a look at MTH's Premier 6 axle AC kings. I've got 4 of them - BNSF, CP 2 flags, UP(with the grey body, that was formerly SP) and CP with the golden "beaver" shield.
I've got a lot that "click" for me... what works for you?
