Power on a large layout can drop in the part of the track that is furthest from the Power Base. These two 3 metre cables will correct the problem, taking power direct to the most distant part of the track and ensuring constant performance. The cable connectors locate tidily into the underside of the track, one cable for each racing lane. Track Power Booster Cables are compatible with both standard and Digital Scalextric layouts.
