For a long time, one of the projects on my bucket list have been a shadow box diorama of  an engine house/workshop at the terminal of “my” railroad, Thamshavnbanen. Thamshavnbanen was a metergauge shortline in Norway with a length of only around 30 km. It did not have more than 5 electric engines, so their rolling stock workshop was of an managable size for a modelling project in 0-scale.  Earlier, I have modelled  one of the engines and a couple of the mineral wagons operated by this railway.
