Another GP40PH-2B on display was the NJT #: 4203. Like the NJT #: 4210 (Erie Unit), this unit was built in October 1968 as Penn Central #: 3222. I'm not quite sure why this unit was on display, the only reason I could think of is that it was painted in the new NJT livery and has been repainted back to the "Disco Stripe" livery.
