The past 1,5 years I've been busy building an 80's town with most of the iconic classic town sets and all 12V grey era train sets. I started with buying sets that I didn't have yet, deyellowing all white and grey (including train tracks) parts which took longer than expected:I wasn't done when the summer of 2019 became autumn and by that time the sun wasn't strong enough (if the sun was visible anyway) so I built a de-yellowing device. I've used a total of 40 liters of peroxide solution to de-yellow most parts. After that I could start building the layout and town.
The town consists of the most iconic classic town sets and three train loops from the 12V grey era. All 12V trains are running on these loops, including a locomotive from the 7777 train ideas book and a 12V crocodile MOC. There are 19 remote controls for points, signs, decouplers and a level crossing. Further more I have used over 120 original 12V light bricks for lighting. These two combined results in a total wire length of around 350 meters. Enjoy! :D
