If I remember correctly, the PRR had only one R1 (4-8-4), which they deemed unsuccessful, and thus the GG1 (4-6-6-4) was developed.
All of the reading I have done on GG1s says that Raymond Lowey decided to have the GG1 body welded for aesthetic reasons, and that it was a first in car body construction.
Can someone shed some light on what I may have missed or misinterpreted ?
