Hi,
Having been a railwayman and a railway modeller for many, many years I discovered a product called 'Trainz' back in about 2005 at Alley Palley model show.
Although I still model 'for real' - G scale in the garden and 00 in the spare room; I have also been getting excellent layouts into Trainz as 3D models.
