I have a new SD45 and am happy with it.  It isn't the most detailed model I have, but it is a good loco.  I know the hoods are thick, but that doesn't bother me .  I have noted that the fuel tank is mounted backwards though.  It isn't noticeable if you havn't seen the prototype, but most of us have.  It is easy enough to correct, but I suggest in future runs, that mistake be fixed.  Only 4 holes in the frame would need to be moved.  Thanks for listening.
