Here is a picture of a 2 set SCX digital track layout I have just setup with a pit section. This sytstem works great. Quality of the set is outstanding. Racing digital compared to analog is a whole new world and being able to place crossovers any where on the track is a definite need. The who issue about length of crossover section is a non-factor. Having many possible passing places is the most important issue. My current setup has 8 crossover sections around the track and two additional for the pit section. SCX has done a excellent job in producing this set.
