Going the extra mile?
In my case, Am I bonkers?
For our 00 gauge/4mm/1:76, whatever you will, I look at the real world and something will stick out and I will wonder if it is do-able on/for the layout (currently Camel Quay) such as adding 'hair' for a dock worker's short beard because his stance reminds me of someone I know who has a beard; adding fine green thread for piping along a bus crew's uniform because the prototype uniform had green piping; making a bishop's cross and chain when it could so easily be painted direct onto the figure; making rosettes, ribbons, hankies, and other accessories to adorn the Morris dancers and 'Obby 'Oss; painting (and weathering) train crew and doing up train and bus passengers and vehicle drivers (and chopping them up to fit!). On a larger scale, replicating detail from photos of 'local' rail side and countryside features or as mentioned above, replicating interiors - and, yes, someone at exhibition is bound to notice - and ask you how you did it or even tell you how they have achieved something that originally sounded like a silly idea or thought maybe just goes too far.
And having gone to the trouble of doing the interior of the Booking Hall based on photos taken on the Mid Hants, Ray added interior lighting - but you have to dip down below the canopy to see it and if there is a train in the station you might not notice, anyway! And if you do dip down to see under the canopy you will also notice some seated passengers and, if you really take note, and look through the window of the rear door, you might just see a passenger coming towards the Booking Hall from the far side of the layout!
Other things I like to play with are perspective and ways of deceiving or leading the eye by the placement of vehicles, figures and such like. Put small vehicles (cars, say) at the rear and larger ones (lorries and buses) at the front of a road disappearing away from you and the road usually looks longer|). Similarly, 00 gauge/4mm figures at the front of the layout, HO figures behind, and N gauge figures in the distance, if possible on a bit of low relief backscene. I doubt people will be conscious of all this, but put things out of place and it will be noticed!
Maybe we just do/try to do these things because we can! I find it fun, especially if it works out and the buzz keeps me motivated. Not only that, it usually means there is always something new on the layout to accompany anything new on the running side (mostly OH's input).
If you think all this is mad. Earlier this year, I made a diorama of a local scene from a postcard for an exhibition. It is no more than 4 inches deep and uses 1:76 scale vehicles. It has opened my eyes to so many more possibilities.
These things, and much greater ones, are do-able, it seems. Go for it. Enjoy doing it. Marvel at what detail is possible. It makes me so much more appreciative of the modelling and ideas of others and that, in turn, keeps me open to modelling. That can't be such a bad thing.
