I think these were posted in some other thread somewhere. And I think I remarked that factory installed sunshades and separate grab-irons was a new development for N scale.
Not sure why people are so down on IM hood locos. The quality is typically comparable to Atlas in recent years. I agree it's a shame neither of those manufacturers has made a good effort on underframe details to hide the contact strips, a la Kato. But I find that otherwise they somehow look a little more realistic than Kato, with their even-more-oversize handrails and glossy paint.
Also any model that uses the Atlas designed 6-axle trucks is going to be growly runner. Oh well.
