I beg to differ! the One does stand for first design of that wheel arrangement, hence the GG1, first and only class of back-to-back 4-6-0s. But cut it in half, and you have just a 4-6-0 again. But PRR had five classes of 4-6-0, culminating in the G5s. Therefore, this beast, born in a later day, must be a G6.
Yet mathematically: (GG1)/2, as in cut in half, equals G1/2
Sorry, but my math is sorely wrong. I have embarrassed myself.
