Terry,
Basic Kato TGV is 6 cars (including 2 x power cars) and is 32"long.
4 car add-on set is available to make a full length TGV which takes the overall length to 52"
Hope this helps.
John.
Hi jdh
The ground cover is mostly grass from the German company NOCH. It is "sprayed" onto the layout from a plastic sqeezy bottle after coating the area with glue (or paint). The bushes are Woodland Scenics foam.
