The updated model list with specific road numbers and reference photo locations has been posted above on the SP ALCO PA tab. One detail we will be including on the late version models has never been produced on commercially available models before. In the 60’s many of the surviving PA’s received a deflector on the roof on each end of the dynamic brake opening. With the help of SP PA sage Bob Zenk we present a view of these difficult to see and yet a critical pieces of PA’s in this era. Models 5406 -1, -2, -3, -4 and 5414 -1, -2, -3, -4 will include these details. Many thanks to Bob for the details and the photos.
