The GP40-2 featured upgraded internal electronics as compared to its predecessor the GP40. While the changes were mostly internal, several outside details such as bolted down battery box covers and a roof that extended slightly beyond the rear of the cab made it visually different from the GP-40. Features Include: * Directional lighting * Walkway safety tread * Blackened metal wheels * Scale speed(TM) motor and dual flywheels * Factory-equipped with AccuMate(R) knuckle couplers * Dynamic brakes (as appropriate for each roadname) * Golden-white LEDs * Prototypical sill detail
