Mini update 22: Still going (yes, really)
There are still many ‘big ticket’ items to deal with, but I can’t be bothered so I’m tinkering (including in post processing - obviously). Not much to update on - have sorted the painted wood colour so its now more properly aligned to ‘Midland Railway Maroon’, track side cable trunking gone in (from very poor photos, so not sure how accurate), have started adding the posters to all the notice boards - will add a bit of life, have put track joins in - they are too close together in terms of reality but done for ‘artistic’ / visual interest reasons, more tweaking the materials and stuff. Just trying to avoid making doing the harder or more finickity stuff 
The colour ones are now using AgX rather than filmic. Definitely darker, but overall I think there is an improvement.
