The Z-Scale
Layout is fully operational, but I am still adding some cars, trucks, people and scenery details.

G-Scale versus Z-Scale.
I've included this photo to visually show the difference in these scales. The two locos are of similar types.
The scale of the larger, G-scale loco is 1:22.5 The scale of the Z-scale loco is 1:220. Thus, the size difference is approximately a factor of ten.
This is a close-up of a portion of the Z-Scale Layout.
Although the size of the rolling stock and buildings is quite small, it's still possible to provide a lot of detail.
For reference there's a 10 cent coin in front of the street light. Note the people on the Bahnhof platform.
