I am a big 40 fan and this EP is an improvement over the previous Poole based 40 - but it would be hard for it not to be! My observations:
I agree with the comments made above regarding the body side panel, panel lines, and the boiler exhaust. All are much too prominent on the body.
The bogie/body gap is about the same as the gap on the last release of Poole based 40s from a few years ago. Ironically, the gap on those models was actually a big larger than on the early Bachmann 40 releases using the Poole body.
To its credit Bachmann have managed to narrow the bogies so that they tuck under the body nicely now, so that from the side the body overhang will mask some of the gap. The big problem however is that from the front - even at normal viewing angles - the gap is always very noticeable because there is (correctly on the model) very little body overhang there.
I was really hoping that Bachmann would be able to narrow the gap and I hope they will still be able too.
The leaf and helical springs on the bogies would benefit from more relief. They are an improvement over the Poole based 40 but they don't have as much relief as the bogie on the Peaks that were released 10 years ago.
The footsteps on the bogie don't quite line up with the door. This is a niggle.
The center head box isn't quite the right shape and it projects too much. The biggest problem with the box, however, may be the ridge immediately around the glazing, which is much too prominent and over scale. I'm actually surprised it has been moulded as I would have thought simply picking it out with paint would have been more to scale. On the disk fitted version, the head code disks are over scale.
The pillars on either side of the center cab window are a bit too wide but are still a vast improvement over the Poole 40. IMHO the cab windows are the weakest part of the Poole 40. Actually, on second thought, if Bachmann paint on the black window frames, the body colour part of the pillars will appear narrower, so this is probably not a problem.
I'm happy to see Bachmann have managed to get a NEM box to fit between the buffer beam and front axle as space is tight there. I also like the representation of the piping above each second axle on the bogies.
Most of the issues above are niggles. IMHO the bogie/body gap and the shape of the center head code box are more than niggles and I hope they are adjusted before production. From a comment above it sounds like Bachmann already have a laundry list of errors to correct and so I am hopeful those issues are addressed.
