I will probably go for another NH green and a single D&H A... got to give it a bit more thought.
D&H owned a total of 5 PAs that were purchased in 1967. 4 from ATSF (59, 60, 62, and 68) that became D&H 16, 17, 18, & 19. The 5th PA was purchased from NH for parts.
Leadership at the D&H wanted a premier passenger train during a time when everyone else was trying to get rid of them. It's a great story from the 70's that flies in the face of conventional railroad practices of the time. The D&H PAs were the first cab units on that railroad. Sadly Amtrak replaced them with Turboliners in 1977.
