First, there is a main line and two branch lines. The main route goes from Karlsruhe via latching city to gaaaaaaannnnnnnnz high to Freudenstadt HBF. Then there's Karlsruhe over Ettlingen up to Wendeschleife Ittersbach. And from Karlsruhe to Bad Herrenalb. The main route runs mostly double track. The rolling stock is very good succeeded. Great sound. But there are some little features here. Two freight locomotives, a tram and a steam locomotive BR 50. In PT 19 Berlin- Rostock more trains are available. But you can on this route to get away, if the muzzle is full of REŽs, ICŽs, and ICEŽs of long-haul freight trips. It is highly recommended !!
