My attic layout is H0 1/87 scale based in Germany black forest area , size is 4.4m x 0.8 for the station run off and the main layout is 3.8m x 3.3m I collect models from Fleischmann,Trix,Marklin,Roco,Faller,Vollmer,Wiking,Herpa,Jagerdndorfer,Electrotren. The system is fully dcc & most locos have sound.The layout is shaped like a big number nine with the terminus branching off the oval, it has three main lines & two stations with many storage areas including a 26 exit Fleischmann turntable.
Automation is now been installed via train controller gold.
I started this layout from models I got from my friend who died in 2009 he started his dream layout in his attic but never finished it so I finished his dream layout in my attic I think he would be happy to see his models running on this layout if he was still alive. No one wanted the dcc sound fleischmann trains so I bought them from his brother at a good price & would never sell them.
I did model GWR & B.R in the past many years ago.
