The Lionel Pennsylvania GG-1 No. 2330 was issued in 1950 and replaced the No. 2332. There were several differences between these two electric engines. The most significant was that this was the first of the GG-1’s to have dual motors and the added feature of Magnetraction. The motors were controlled by a three position directional unit whose control lever protrudes though the top of the engine.
The body was painted a dark BRUNSWICK GREEN color with GOLD lettering and stripes. There was the usual fading of the five GOLD rubber-stamped stripes that has been found on units that are brand new in the box. This was caused by the reaction of the rubber-stamped striping to the paint overcoat that Lionel used on these units. The lettering was heat-stamped and there is a RED keystone PRR decal in the upper center of the sides. Additional similar decals that are numbered "2330" adorn both ends of this engine. There are ornamental horns on top in addition to the two operating pantographs that could be used to power this GG-1 from an overhead catenary system. This engine is lighted in both directions and has two electronic coil couplers at the ends.
The graduated height of the air vents would be continued in this version, but the vibrator box horn used on the No. 2332 gave way to a more realistic horn that was powered by a 1.5 volt D size Battery. In addition to checking for battery damage at the base of the engine collectors should look at the windows in the center of the engine for battery leakage in the event that the engine was stored with the top down.
