Just my 2p-worth about 'Banger Blue' - It's my impression that it's modelled mostly by 'those who were there'. On the face of it, it seems like a boring Era when everything was one colour; in reality the variety was in the amount of different loco classes around (albeit dwindling throughout that time) and the still very "regional" nature of the railways; you had to travel to different places to see certain Classes. People who didn't experience the Blue Era (either too young, or too old and still mourning Steam) can't perhaps appreciate that, and so don't model that Era.
Somehow, the 'Green' Era does seem to be an area of increasing interest recently, myself included; despite my trainspotting years being the Blue era (1977 onwards), I'm getting more interested in the era I just missed, either because I wasn't born yet (1967, so missed steam really) or just too young to even know about it at the time, such as WR Hydraulics. As an aside, since it overlaps with Steam, which magazine would Green era layouts go in, if there was a rigid distinction?
For a magazine where the modelling is always D&E-focused, I quite like Rail Express. In fact for me it would be no bad thing if it became a modelling magazine with a 'Real Trains' supplement section!!
As my main interest is American trains, it might be assumed I'd call for more of a mix of 'Foreign' with British in the mags; in actual fact I can see why it doesn't happen, besides the inherent xenophobia of a lot of UK modellers. I can see that a 'mixed' approach just can't do justice to all those interests. For example, I rarely buy Continental Modeller. If it has any American content, it is usually just one article, & that might be a 'Logging Line', so often - however good the modelling is - most of it is outside my core interests*, including most of the adverts. I think the same would happen to a mag that tried to split it's content between UK & US subjects. As American mags are available, far easier to get those - and they rarely publish anything about 'foreign' trains, either!!
* I realise that this conflicts with my attitude at Exhibitions, where I make an effort to view (as opposed to 'glance at in passing') every layout, regardless of subject matter etc.
