Lego 4548 Transformer and Speed Regulator |
|
The Lego 4548 Transformer and Speed Regulator is a device for the 9 volt line to control the speed of the train. 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, 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. The Lego 4548 Transformer and Speed Regulator was released in 1991, contains 3 pieces and includes 0 minifigures. |
