referring to the drawings , an illustrative embodiment of the car racing system is generally indicated by reference numeral 1 . the car racing system 1 includes an elongated track 2 having a first panel end 2 a and a second panel end 2 b . the track 2 may be plastic or other suitable material and has a racing surface 3 . multiple , adjacent , parallel track slots 4 extend into the racing surface 3 of the track 2 . in an illustrative embodiment of the car racing system 1 , four track slots 4 extend into the racing surface 3 , although this number may vary . accordingly , the track slots 4 include a pair of inner track slots 4 a and a pair of outer track slots 4 b . as shown in fig1 - 3 , a second vehicle start panel 8 extends from the second panel end 2 b of the track 2 . a pair of second vehicle start switches 9 a is provided on the second vehicle start panel 8 , at the ends of respective track slots 4 . for example , as shown in fig3 , in some embodiments , a pair of second vehicle start switches 9 a is provided on the second vehicle start panel 8 at the ends of the respective inner track slots 4 a . as shown in fig1 , 2 and 4 , a first vehicle start panel 14 extends from the first panel end 2 a of the track 2 . a pair of second vehicle finish switches 9 b is provided on the first vehicle start panel 14 , typically at the ends of the respective inner track slots 4 a . first vehicle start switches 18 a are provided on the first vehicle start panel 14 , at the ends of respective track slots 4 , such as at the ends of the respective outer track slots 4 b , for example . as shown in fig1 , 3 and 4 , a pair of inner power rails 5 a is embedded in the racing surface 3 of the track 2 , on respective sides of each inner track slot 4 a . each pair of inner power rails 5 a extends between the corresponding second vehicle start switch 9 a on the second vehicle start panel 8 and second vehicle finish switch 9 b on the first vehicle start panel 14 . a corresponding pair of outer power rails 5 b is embedded in the racing surface 3 , on respective sides of each corresponding outer track slot 4 b . each pair of outer power rails 5 b extends between each first vehicle start switch 18 a on the first vehicle start panel 14 and the corresponding first vehicle finish switch 18 b on the second vehicle start panel 8 . an electrical transformer 15 is provided on one of the second vehicle start panel 8 and the first vehicle start panel 14 . in the illustrative embodiment of the car racing system shown in the drawings , the transformer 15 is provided on the first vehicle start panel 14 . the transformer 15 is electrically connected to each of the second vehicle start switches 9 a and first vehicle finish switches 18 b on the second vehicle start panel 8 and to each of the first vehicle start switches 18 a and second vehicle finish switches 9 b on the first vehicle start panel 14 . a power cord 16 , which terminates in a plug 17 , extends from the transformer 15 . the plug 17 may be adapted for insertion in a standard household electrical outlet ( not shown ). a pair of controls 22 includes a pair of control handles 23 , each of which may have a generally l - shaped configuration . a spring - loaded trigger 24 is provided on each control handle 23 . each control handle 23 is electrically connected to the transformer 15 through a corresponding pair of control wiring 25 . the transformer 15 is electrically connected to each first vehicle start switch 18 a and each second vehicle finish switch 9 b on the first vehicle start panel 14 . through the transformer 15 , the trigger 24 of each control 22 is electrically connected to the corresponding first vehicle start switch 18 a , first vehicle finish switch 18 b and corresponding second vehicle finish switch 9 b . normally , each first vehicle start switch 18 a is in the open position . depression of the trigger 24 causes the corresponding first vehicle start switch 18 a to close , thereby establishing electrical communication between the transformer 15 and corresponding pair of outer power rails 5 b . upon release of the trigger 24 , the first vehicle start switch 18 a opens , thereby terminating electrical communication between the transformer 15 and corresponding pair of outer power rails 5 b . each first vehicle finish switch 18 b is electrically connected to the corresponding adjacent second vehicle start switch 9 a on the second vehicle start panel 8 . each first vehicle finish switch 18 b is normally closed and forms a complete circuit with the corresponding first vehicle start switch 18 a . upon activation typically in a manner which will be hereinafter described , each first vehicle finish switch 18 b closes the corresponding adjacent second vehicle start switch 9 a . this electrically energizes the pair of inner power rails 5 a which extend between each second vehicle start switch 9 a and corresponding second vehicle finish switch 9 b , as long as the trigger 24 on the corresponding control 22 remains depressed . normally , each second vehicle finish switch 9 b remains closed unless and until activated typically in a manner which will be hereinafter described . each of a pair of first vehicles 30 and a pair of second vehicles 32 is supported by the racing surface 3 of the track 2 . in typical application , each of the pair of first vehicles 30 is a car and each of the pair of second vehicles 32 is a motorcycle . each of the first vehicles 30 and each of the second vehicles 32 may have a conventional “ slot car ” design . as shown in fig3 , each of the pair of first vehicles 30 typically includes a chassis 30 a which is rendered portable on the racing surface 3 by wheels 30 b . an electric motor 31 ( shown in phantom ) is provided in the chassis 30 a . the motor 31 drivingly engages at least one of the wheels 30 b . at least one of the wheels 30 b is electrically conductive and is electrically connected to the motor 31 to power the motor 31 , typically conventional slot car design . each of the pair of second vehicles 32 typically includes a frame 32 a which is rendered portable on the racing surface 3 by wheels 32 b . an electric motor 33 ( shown in phantom ) is provided on the frame 32 a and drivingly engages at least one of the wheels 32 b . a tab ( not shown ) extends from the frame 32 a of each second vehicle 32 and is inserted in the corresponding inner track slot 4 a . in like manner , a tab ( not shown ) also extends from the chassis 30 a of each first vehicle 30 and is inserted in the corresponding outer track slot 4 b . when each first vehicle 30 and each second vehicle 32 is so positioned on the racing surface 3 , each wheel 30 b of the first vehicle 30 contacts a corresponding outer power rail 5 b . in like manner , when each second vehicle 32 is so positioned on the racing surface 3 , each wheel 32 b of the second vehicle 32 contacts an inner power rail 5 a . therefore , electrical power is transferred from the outer power rail 5 b to the motor 31 of each first vehicle 30 through the wheel or wheels 30 b . in like manner , electrical power is transferred from the inner rail 5 a to the motor 33 of each second vehicle 32 through the wheel or wheels 32 b . as shown in fig1 , in typical application , the first vehicles 30 are positioned at the respective first vehicle start switches 18 a on the first vehicle start panel 14 . the second vehicles 32 are positioned at the respective second vehicle start switches 9 a on the second vehicle start panel 8 . competing players ( not shown ) hold the respective controls 22 . each of the controls 22 controls a corresponding one of the first vehicles 30 and a corresponding one of the second vehicles 32 . accordingly , upon depression of the trigger 24 of each control 22 , the corresponding first vehicle start switch 18 a is closed , energizing the outer power rails 5 b . this facilitates traversal of the first vehicle 30 along the racing surface 3 of the track 2 , toward and ultimately against the corresponding first vehicle finish switch 18 b . therefore , the first vehicle finish switch 18 b closes the corresponding adjacent second vehicle start switch 9 a , energizing the corresponding pair of inner power rails 5 a . this facilitates traversal of the second vehicle 32 along the racing surface 3 , toward and ultimately against the corresponding second vehicle finish switch 9 b . in response , the second vehicle finish switch 9 b is opened , terminating flow of electrical power to the inner power rails 5 a . the player who controls the second vehicle 32 which reaches the corresponding second vehicle finish switch 9 b first is typically the winner . while the preferred embodiments of the invention have been described above , it will be recognized and understood that various modifications can be made in the invention and the appended claims are intended to cover all such modifications which may fall within the spirit and scope of the invention .
