An important adjunct to the modelling of railways is that buses & other model vehicles are correct for the era modelled. I hope to add content covering this important aspect to this site in the near future.
There is also the possibility of stand alone dioramas of street scenes, covering bus & scenery modelling, based on prototype photographs
