Where it all started, our Marklin Z scale layout! My grandfather started this layout about 11 years ago, being so fascinated with how tiny they are. I learned everything about model trains from him and through this very layout build. I inherited his layout (#cancersucks) before we got to finish and wire it all. But two years later, it's a fully functional layout with 9 powered turnouts and a transfer table! #trains #modeltrains #modelbahn #marklin #märklinz #zscale #hobby #family #diorama #train
