Hello,
I decided to convert the Märklin layout „Hauptbahnhof und Nebenbahnhof“ 6.2.9 of Gleisanlagen-Buch Z into scale 1:450.
The turntable has just be done like this
and has to be finished by adding electronic, motor, gear and accessories.
The Märklin arch bridge 8975, straight ramp 8976 and curved ramp 8977 are just under CAD construction and will be printed soon.
BR,
Siegfried
