“The set includes three pieces, one being the speed regulator, the Transformer, and the rail connecter. The train connector was a set of wires that would connect to the rails, and the other side would connect the speed regulator itself. It is most similar to the 12 volt line,... More seeing both use a speed regulator, and use electric charged rail but the 9 volt line perfected it. This set itself was a back-up or an extra for any Lego train Track and was bought if the original one broke. This would make a great addition to any Lego train track.”
