Due to the spring-loaded contact pins at the end of the U-profiles (conductors), a permanent and perfect rail contact is guaranteed, as well as optimal power supply. The new system allows for the construction of long track layouts with almost no voltage loss. Corrosion-free conductors made of Nirosta stainless steel ensure durability. Rigid plastic provides vibration-free operation, a stable rail system, and perfect rail contact. There are options for 4, 6, and 8-track expansions. An innovative locking system enables an optimal connection of the individual rails, making it easier and completely hassle-free to connect rail pieces. The rails maintain optimal cohesion even under extreme conditions.
