I just noticed from pictures in P-RSL In Color Vol. 2 that several of the Baldwin AS-16's are sporting Reading RR style rain gutters on the roof of the cab. I had never noticed this feature before. The loco's I spotted were 6022, 6023, 6024, 6025 and 6027. Were these units acquired from the Reading and renumbered or were they part of a Reading order with Baldwin and built to the same specs?
