Alco PAs 77 and 74. 74 has new grills to replace wreck damage.
Do you recall what the road numbers were on these engines?
Those were #77 and #74. A few PAs had their grills replaced with Phar type after they were damaged. I know #60 also had replacement grills after a sideswipe accident.
If a diesel loco could be sexy, this was it.
These diesels make today's units simply look bad by comparison.
