C182 Change Over Track
The end of one of the wires may have broken off and would require soldering back on.
The Scalextric catalogue no. 21 of 1980 has the following description "C.182 Changover Tracks. Crossover from the inside lane to the outside while racing at speed with the changeover tracks. Changeover tracks are a must for flat circuits where an unfair advantage could be gained if a driver has the inside lane on every bend. For extra exitement add another two changeover tracks and create the 'double crossover'."
