The adjustable switch make only really a Elektrolock fun. Even driving in the direction in which the switch is just not made usually leads to the fact that the E-Lock including accompanying car remains and further runs on the tracks. The fun factor is certainly increased with the adjustable switch many times and the wooden train is since much more interesting and therefore more frequently in use. PS: An Assortment Set (rails with hole-hole and male-male) is recommended in addition, since the driving in the direction in which divides the switch is recommended, and that both switches can be driven in part direction.
