There are not many places where JR and non-JR share tracks. Toyohashi is one of the exceptions where JR Iida Line and Meitetsu Main Line share the tracks into Toyohashi station. The picture is taken from a Iida Line train arriving at Toyohashi. (The picture is awful technically, but as it shows a nice oddity...) As it exist in the real world, it can exist on any layout!
