What can I say about the GG1 that hasn't already been said, by people far more knowledgeable than me.

| Notes | There are few locomotives as recognizable as the PRR GG1. This is the first standard scheme applied to these passenger electrics. Though it looks like a solid wide stripe, it's the most accurate representation of the five-stripe scheme I could achieve, at this scale. Early in their careers, the striping and other markings were applied with gold leaf. Originally lettered with the sans-serif "Futura" font, the roadname an numbers changed to the serif "Clarendon" style, when it was adopted in 1941. This image represents the appearance of these "motors" between 1941 and 1952. |

| Notes | In 1952 and '53 PRR painted 10 GG1s Tuscan Red, to better match the cars of The Congressional and Senator, which had Markings painted over Tuscan backgrounds. These motors also marked the change from gold leaf markings to a shade known as "Dulux Gold" (Dulux was a brand name for DuPont paints). The change made the markings more visible, and eliminated the extra maintenance required by the metallic paint. |

| Notes | Not only the red GG1s got the Dulux Gold markings. After 1952, any GG1 that needed painting got the new color. |

| Notes | In 1955, PRR introduced a whole new scheme, consisting of enlarged lettering, a single wide stripe, and a much bigger keystone herald. This scheme lasted until the Penn Central merger. |
